Depending on manufacturer, colour of red restrictor may tend  
more towards orange.  
To avoid altering the cooling output of the air conditioner, only  
red-coloured restrictors are to be fitted.  
From vehicle identification number 429 DN 000751 onwards  
(manufactured from 11.2013), the quantity of refrigerant in the  
circuit was increased from 650 g to 680 g and the quantity of  
refrigerant oil from 150 ccm to 200 ccm. The increased amount  
of refrigerant and refrigerant oil also applies to all earlier ve‐  
hicles. On vehicles manufactured up to the vehicle identifica‐  
tion number mentioned, check whether the refrigerant oil has  
already been topped up during a previous workshop visit. If  
not, add 50 ccm of refrigerant oil to the refrigerant circuit. Then  
check the refrigerant capacity indicated on the label and if  
necessary attach a new label with the correct capacity and the  
appropriate language (e.g. the label with part number  
420 010 535 and index BA in German and English) ⇒ Elec‐  
tronic parts catalogue and ⇒ Heating, air conditioning; Rep.  
gr. 87 ; Installation location overview - Air conditioning (vehi‐  
cle-specific Workshop Manual). If no label with the correct  
capacity and the appropriate language is available, alter the  
capacity indicated on the existing label accordingly with a wa‐  
terproof pen. Then increase the refrigerant oil quantity in the  
refrigerant circuit by 50 ccm and charge the refrigerant circuit  
with the quantity of refrigerant shown above

Air conditioner with refrigerant R134a - Edition 11.2018  
Note  
PAG (polyalkylene glycol) oil is highly hygroscopic (attracts  
water); open containers should therefore be closed immedi‐  
ately so that they are air-tight.  
A use-by date for the refrigerant oil is stated on the bottle in  
which the refrigerant oil is supplied. This date is not relevant if  
the bottle is sealed air-tight. If the bottle is sealed air-tight, the  
refrigerant oil can also be used after the date stated on the  
bottle.  
PAG oil becomes unusable if it is stored in open containers for  
a long period of time.

10.2.1  
Approved refrigerant oils  
Note  
The oils used with refrigerant R12 are not suitable for refrig‐  
erant R134a.  
The name of the compressor manufacturer “Nippondenso”  
has been changed to “Denso”.  
The special refrigerant oils to be used exclusively for refriger‐  
ant circuits with refrigerant R134a are not always commercial‐  
ly available.  
Refrigerant oils intended specifically for a particular air condi‐  
tioner compressor can therefore be obtained from the replace‐  
ment parts range ⇒ Electronic parts catalogue .  
If a defective air conditioner compressor is replaced by a com‐  
pressor from a different manufacturer, it is important to check  
whether the refrigerant oil already in the refrigerant circuit  
(from the removed compressor) is also approved for the new  
compressor. If a different refrigerant oil is approved for the new  
air conditioner compressor than for the removed compressor,  
the refrigerant circuit must be flushed  
⇒ “5.5 Cleaning (flushing) refrigerant circuit with refrigerant  
R134a”, page 100 .  
Using other refrigerant oils may cause the system to fail, as it  
cannot be guaranteed that they will mix and circulate with re‐  
frigerant R134a to lubricate the air conditioner compressor.  
There are different refrigerant oils for “Zexel/Valeo”, “Denso”,  
“Delphi/Mahle” and “Sanden” compressors. ⇒ Electronic parts  
catalogue  
The logo of the compressor manufacturer “Zexel” attached to  
the air conditioner compressor was modified from “Zexel” to  
“Valeo” from year of production 2006 onwards (change in  
manufacturer's name).  
The refrigerant oil (part no. G 052 300 A2; external designation  
ND 8) for use in refrigerant circuits with “Denso” (formerly  
“Nippondenso”) air conditioner compressors is also included  
in the retrofit kit (part no. 4A0 298 107 A). It is the same for  
mechanically and electrically driven air conditioner compres‐  
sors ⇒ Electronic parts catalogue .  
For refrigerant circuits with “Zexel/Valeo” air conditioner com‐  
pressors, use refrigerant oil with part no. G 052 154 A2 ⇒  
Electronic parts catalogue .  
For refrigerant circuits with mechanically driven “Sanden” air  
conditioner compressors, use refrigerant oil with part no. G  
052 154 A2 (or part no. G 052 535 M2) ⇒ Electronic parts  
catalogue .  
For mechanically driven “Sanden” air conditioner compres‐  
sors, refrigerant oil with part no. G 052 535 M2 (external  
designation SP A2) can be used instead of refrigerant oil with  
part no. G 052 154 A2 (external designation SP 10) ⇒ Elec‐  
tronic parts catalogue .  
For refrigerant circuits with electrically driven “Visteon” or  
“Sanden” air conditioner compressors (e.g. in the Audi A3 e-  
tron and Audi Q7 e-tron), use refrigerant oil with part no. G 052  
535 M2 ⇒ Electronic parts catalogue .  
For refrigerant circuits with “Delphi/Mahle” compressor, you  
can use refrigerant oil with part no. G 052 154 A2 or refrigerant  
oil with part no. G 052 300 A2 ⇒ Electronic parts catalogue .

Air conditioner with refrigerant R134a - Edition 11.2018  
For refrigerant circuits with “Zexel / Valeo” air conditioner com‐  
pressors, use can be made of both the refrigerant oil (G 052  
154 A2) and the refrigerant oil (G 052 200 A2) contained in the  
retrofit kit (part no. 4A0 298 107) ⇒ Electronic parts catalogue .  
At present, the electrically driven air conditioner compressor  
(e.g. of “Denso” type on the Audi Q5 Hybrid) is filled with the  
same refrigerant oil as the mechanically driven air conditioner  
compressor of the same manufacturer (refer to rating plate on  
air conditioner compressor) ⇒ Electronic parts catalogue .  
To ensure that air conditioner service stations do not always  
need to be cleaned before starting work on a different type of  
vehicle (due to the different refrigerant oils used depending on  
the manufacturer of the air conditioner compressor), specified  
small quantities (up to max. 10%) of the total quantity of re‐  
frigerant oil in the corresponding refrigerant circuit are permit‐  
ted to meet a different specification from that of the air  
conditioner compressor installed. On Audi vehicles, this  
means that it is permitted to use max. 10% refrigerant oil of  
the type SP 10 (or SP A2) on vehicles with a “Denso” air con‐  
ditioner compressor (with ND 8 refrigerant oil) or max. 10%  
refrigerant oil of the type ND 8 on vehicles with a “Sanden”,  
“Delphi/Mahle” or “Visteon” air conditioner compressor (with  
SP 10 or SP A2 refrigerant oil). However, other refrigerant oils  
not listed here must not be used (different properties due to  
different viscosity, different/missing additives etc.).  
Instead of using an air conditioner service station, refrigerant  
oil extracted when emptying the refrigerant circuit can be add‐  
ed via an open connection or, when valve -3- is removed, via  
a service connection -1- or -2- using a commercially available  
disposable syringe  
⇒ “3.5 Connections for quick-release coupling in refrigerant  
circuit”, page 51 before evacuating the refrigerant circuit. This  
may be practical e.g. if the refrigerant oil specified for the re‐  
frigerant circuit is normally only rarely used. The refrigerant oil  
added must always be fresh ⇒ “2.8 Refrigerant oil”, page 13  
and ⇒ Electronic parts catalogue . The positioning of service  
connection -1- or -2- in the vehicle is different ⇒ Heating, air  
conditioning; Rep. gr. 87 ; Installation location overview - Air  
conditioning (vehicle-specific Workshop Manual).  
Important information:  
As refrigerant oil is extremely hygroscopic, open containers must  
be closed and re-sealed immediately after use to prevent mois‐  
ture from entering.  
Note  
A use-by date for the refrigerant oil is stated on the bottle in  
which the refrigerant oil is supplied.  
This date is not relevant if the bottle is sealed air-tight.  
If the bottle is sealed air-tight, the refrigerant oil can also be  
used after the date stated on the bottle.

Refrigerant oil capacities  
Note  
For the assignment of the air conditioner compressor (“Zexel/  
Valeo”, “Sanden” or “Denso”), refer to the vehicle-specific  
Workshop Manual ⇒ Heating, air conditioning; Rep. gr. 87 ;  
Refrigerant circuit (vehicle-specific Workshop Manual) and ⇒  
Electronic parts catalogue .  
The logo of the compressor manufacturer “Zexel” attached to  
the air conditioner compressor was modified from “Zexel” to  
“Valeo” from year of production 2006 onwards (change in  
manufacturer's name).  
With “Zexel / Valeo”, “Denso” and “Sanden” compressors, the  
amount of refrigerant oil in the replacement compressor cor‐  
responds to the total quantity of oil to be added. When renew‐  
ing the air conditioner compressor, the quantity of refrigerant  
oil in the compressor to be fitted must therefore be adjusted  
(an incorrect refrigerant oil quantity will cause damage to the  
compressor).  
When pouring (flushing) the refrigerant oil out of the replace‐  
ment compressor (or the defective air conditioner compres‐  
sor), a small quantity of oil generally remains in the  
mechanically driven air conditioner compressor (20 to 30  
3
cm ). This refrigerant oil does not affect the function of the air  
conditioner and can therefore be ignored (always remains in  
the compressor). A larger quantity of refrigerant oil may remain  
in the electrically driven air conditioner compressor depending  
on the structure and version, which may mean that the air  
conditioner compressor may need to be flushed to empty it  
⇒ “5.5.2 Flushing electrically driven air conditioner compressor  
(removing refrigerant oil)”, page 119 .  
On initial switch-on, the refrigerant oil is distributed throughout  
the refrigerant circuit.  
Unless otherwise stated, the refrigerant oil capacities specified  
also apply to the corresponding “S” and “RS” versions of this  
vehicle model.  
For refrigerant oil quantities required for topping up when re‐  
newing defective refrigerant circuit components, refer to

Note  
The replacement compressor contains the full quantity of oil  
intended for the refrigerant circuit. If the air conditioner com‐  
pressor is renewed, the quantity of oil in the compressor must  
therefore be adjusted accordingly ⇒ page 272 .  
Different air conditioner compressors are fitted depending on  
the production period and engine.  
At the start of production, “Denso” air conditioner compressors  
(type “6 SEU 14C”) or “Sanden” air conditioner compressors  
(“7 PXE 16/14”) were fitted; see ⇒ Electronic parts catalogue  
and ⇒ Heating, air conditioning; Rep. gr. 87 ; Refrigerant cir‐  
cuit (vehicle-specific Workshop Manual).  
Depending on the engine, “Sanden” air conditioner compres‐  
sors (type “11 PXC 14”) or “Delphi/Mahle” air conditioner  
compressors (type “6 CVC 140”) may also be fitted at a later  
date (introduction not yet finalised, planned from 09.12 on‐  
wards); see ⇒ Electronic parts catalogue and ⇒ Heating, air  
conditioning; Rep. gr. 87 ; Refrigerant circuit (vehicle-specific  
Workshop Manual).  
At a later date, air conditioner compressors manufactured by  
“Denso” or “Sanden” in another version may be installed de‐  
pending on the engine (introduction not yet finalised) ⇒ Elec‐  
tronic parts catalogue .  
These air conditioner compressors are available as replace‐  
ment parts with different oil capacities, so it is important to pay  
attention to the oil quantity in the air conditioner compressor  
and to check the exact part number ⇒ Heating, air condition‐  
ing; Rep. gr. 87 ; Refrigerant circuit (vehicle-specific Work‐  
shop Manual) and ⇒ Electronic parts catalogue .  
The different oil quantities in the air conditioner compressor  
may result from the design of the air conditioner compressor  
(with or without oil separator at high-pressure connection) or,  
in the case of identical air conditioner compressors, from the  
design of the refrigerant circuit; pay attention to these quanti‐  
ties. Too much oil in the circuit results in higher pressures and  
a reduced cooling output of the system. Too little oil may lead  
to lubrication problems in the air conditioner compressor.  
The air conditioner compressor may have been fitted at the  
factory with a type plate indicating the part number and the  
quantity of refrigerant oil in the air conditioner compressor.  
As of 11.2012, the quantity of refrigerant oil for the “Denso” air  
conditioner compressor with part number “5Q0 xxx xxx” was  
gradually increased from 80 ccm to 110 ccm. The increased  
quantity of refrigerant oil applies retroactively to all vehicles  
with this air conditioner compressor. On vehicles manufac‐  
tured with this air conditioner compressor up to 11.2012, check  
whether the quantity of refrigerant oil has already been in‐  
creased during a previous workshop visit. If not, add 30 ccm  
of refrigerant oil to the refrigerant circuit . Then enter the re‐  
frigerant oil capacity on the label in waterproof ink ⇒ Heating,

Note  
The replacement compressor contains the full quantity of oil  
intended for the refrigerant circuit. If the air conditioner com‐  
pressor is renewed, the quantity of oil in the compressor must  
therefore be adjusted accordingly ⇒ page 272 .  
Different air conditioner compressors are fitted depending on  
the production period and engine.  
At the start of production, exclusive use was made of air con‐  
ditioner compressors of type “7 SEU 16” from “Denso” (e.g. air  
conditioner compressor with part no. 1K0 820 803 up to index  
“D”). In Model Year 2004 (as of approx. 10.03), a gradual  
change was made to a different type of “Denso” compressor  
(“7 SEU 17” e.g. air conditioner compressor with part no. 1K0  
820 803 as of index “E”).  
With effect from Model Year 2004 (as of approx. 10.03), “Zex‐  
el / Valeo” (type “DSC17E”) and “Sanden” (type “PXE16”) air  
conditioner compressors are also gradually being introduced  
depending on the engine ⇒ Electronic parts catalogue .  
The logo of the compressor manufacturer “Zexel” attached to  
the air conditioner compressor was modified from “Zexel” to  
“Valeo” from year of production 2006 onwards (change in  
manufacturer's name).  
From model year 2008 onwards, “Denso” compressors (type  
“6 SEU 14”) and “Delphi/Mahle” air conditioner compressors  
are also gradually being introduced depending on the engine  
⇒ Electronic parts catalogue and ⇒ Heating, air conditioning;  
Rep. gr. 87 ; Refrigerant circuit (vehicle-specific Workshop  
Manual).  
This air conditioner compressor is available as a replacement  
part with different oil capacities, so it is important to pay at‐  
tention to the oil quantity in the compressor and to check the  
exact part number ⇒ Heating, air conditioning; Rep. gr. 87 ;  
Refrigerant circuit (vehicle-specific Workshop Manual) and ⇒  
Electronic parts catalogue .  
The different oil quantities in the air conditioner compressor  
may result from the design of the air conditioner compressor  
(with or without oil separator at high-pressure connection) or,  
in the case of identical air conditioner compressors, from the  
design of the refrigerant circuit; pay attention to these quanti‐  
ties. Too much oil in the circuit results in higher pressures and  
a reduced cooling output of the system. Too little oil may lead  
to lubrication problems in the air conditioner compressor.  
The air conditioner compressor may have been fitted at the  
factory with a type plate indicating the part number and the  
quantity of refrigerant oil in the air conditioner compressor.

Note  
The replacement compressor contains the full quantity of oil  
intended for the refrigerant circuit. If the air conditioner com‐  
pressor is renewed, the quantity of oil in the compressor must  
therefore be adjusted accordingly ⇒ page 272 .  
Different air conditioner compressors are fitted depending on

part with different oil capacities, so it is important to pay at‐  
tention to the oil quantity in the compressor and to check the  
exact part number ⇒ Heating, air conditioning; Rep. gr. 87 ;  
Refrigerant circuit (vehicle-specific Workshop Manual) and ⇒  
Electronic parts catalogue .  
The reason for the different oil quantities in the air conditioner  
compressor may be the design of the air conditioner compres‐  
sor, or the design of the refrigerant circuit on vehicles with an  
identical air conditioner compressor; please note the different  
oil quantities. Too much oil in the circuit results in higher pres‐  
sures and a reduced cooling output of the system. Too little oil  
may lead to lubrication problems in the air conditioner com‐  
pressor.  
The air conditioner compressor may have been fitted at the  
factory with a type plate indicating the part number and the  
quantity of refrigerant oil in the air conditioner compressor.  
As of 11.2012, the quantity of refrigerant oil for the “Denso” air  
conditioner compressor was gradually increased from 80 ccm  
to 110 ccm. The increased quantity of refrigerant oil applies  
retroactively to all vehicles with this make of air conditioner  
compressor. On vehicles manufactured up to 06.2013, check  
whether the quantity of refrigerant oil has already been in‐  
creased during a previous workshop visit. If not, add 30 ccm  
of refrigerant oil to the refrigerant circuit . Then enter the re‐  
frigerant oil capacity on the label with a waterproof pen ⇒  
Heating, air conditioning; Rep. gr. 87 ; Refrigerant circuit (ve‐  
hicle-specific Workshop Manual), and fill the refrigerant circuit  
with the quantity of refrigerant indicated above  
⇒ “10.1.5 Capacities for Audi Q2 (GA_) 2017 ►, Audi A3 (8V_  
or 85_ for China) 2013 ►, Audi A3 e-tron (8V_ ) 2015 ►, Audi  
RS 3 (8V_) 2016 ►”, page 299 .  
The refrigerant oil used in the Audi A3 e-tron must be different  
to the oil used in vehicles with a mechanically driven air con‐  
ditioner compressor (e.g. refrigerant oil with the part number  
G 052 535 M2) ⇒ Electronic parts catalogue . Since the stor‐  
age tanks in most air conditioner service stations do not con‐  
tain this refrigerant, the refrigerant oil extracted when empty‐  
ing the refrigerant circuit cannot be refilled from the air  
conditioner service station. On these vehicles, refrigerant oil  
can be refilled via a service connection e.g. before evacuating  
the refrigerant circuit via an open connection or with valve re‐  
moved ⇒ page 335 .  
For refrigerant circuits with electrically driven “Visteon” or  
“Sanden” air conditioner compressors (e.g. in the Audi A3 e-  
tron), use refrigerant oil with part no. G 052 535 M2 ⇒

The Audi A4 is fitted with different air conditioner compressors  
depending on the engine and production period. This air con‐  
ditioner compressor is available as a replacement part with  
different oil capacities, so it is important to pay attention to the  
exact part number ⇒ Heating, air conditioning; Rep. gr. 87 ;  
Refrigerant circuit (vehicle-specific Workshop Manual) and ⇒  
Electronic parts catalogue .  
At the start of production, the compressor types in the first line  
of the table were supplied with a refrigerant oil quantity of 180  
3
cm . These air conditioner compressors can be recognised  
from the index of the part number (8E0 260 805 with one index  
or with double index up to “AH”). In model year 2004 (as of  
approx. 01.04), a gradual change was made to other types of  
3
compressor with a refrigerant oil quantity of 120 cm or 130  
3
cm . These air conditioner compressors can be recognised  
from the index of the part number 8E0 260 805 (with double  
index as of “AJ”) or 4F0 260 805 (and index “E” for vehicles  
with 8-cyl. engine) ⇒ Electronic parts catalogue .  
The different oil quantities in the air conditioner compressor  
may result from the design of the air conditioner compressor  
(with or without oil separator at high-pressure connection) or,  
in the case of identical air conditioner compressors, from the  
design of the refrigerant circuit; pay attention to these quanti‐  
ties. Too much oil in the circuit results in higher pressures and  
a reduced cooling output of the system. Too little oil may lead  
to lubrication problems in the air conditioner compressor.

Air conditioner with refrigerant R134a - Edition 11.2018  
Note  
Between June and August 2012, the refrigerant circuit (air  
conditioner compressor, condenser, evaporator etc.) was  
gradually converted (depending on the engine and the vehicle  
version). This means that the refrigerant and refrigerant oil  
capacity for these vehicles has also changed (indicated on la‐  
bel for refrigerant circuit) ⇒ page 307 , ⇒ Heating, air condi‐  
tioning; Rep. gr. 87 ; Refrigerant circuit (vehicle-specific  
Workshop Manual) and ⇒ Electronic parts catalogue .  
On the Audi Q5 hybrid there is no conversion of the refrigerant  
circuit in model year 2012 (see other versions).  
From August 2011 onwards, air conditioner compressors with  
air conditioning system magnetic clutch - N25- were gradually  
introduced for certain 4-cyl. TDI engines ⇒ Electronic parts  
catalogue .  
From the outside, the modified components (air conditioner  
compressor, condenser) can only be identified by the part  
numbers (label on air conditioner compressor, type plate or  
lettering on condenser)  
⇒ “10.1.11 Capacities for Audi A4 (8K_) 2008 ►, Audi A5  
Coupé and Sportback (8T_) 2008 ►, Audi Q5 (8R_ or 83_ for  
China) 2008 ►, Audi A5 Cabriolet (8F_) 2009 ►, Audi Q5 hybrid  
(8R_) 2011 ►”, page 307 and ⇒ Electronic parts catalogue .  
At the start of production, the Audi Q5 hybrid is fitted with an  
electrically driven “Denso” air conditioner compressor ( elec‐  
trical air conditioner compressor - V470- with control unit for  
air conditioning compressor - J842- ). There is no provision for  
an air conditioner compressor regulating valve - N280- on this  
air conditioner compressor.  
At the start of production, the Audi Q5 hybrid was fitted with  
an air conditioner compressor with a refrigerant oil quantity of  
160 ccm. Shortly after the start of production, the refrigerant  
oil quantity was increased to 200 ccm. The refrigerant oil does  
not have to be topped up on vehicles fitted with an air condi‐  
tioner compressor with a refrigerant oil quantity of 160 ccm.  
However, if the refrigerant circuit has been cleaned (flushed)  
for example, a total of 200 ccm should also be filled in this  
vehicle as the specified refrigerant oil quantity. The correct  
amount of refrigerant oil will already be filled into a replace‐  
ment air conditioner compressor ⇒ Electronic parts cata‐  
logue .

Further notes  
Note  
The replacement compressor contains the full quantity of oil  
intended for the refrigerant circuit. If the air conditioner com‐  
pressor is renewed, the quantity of oil in the compressor must  
therefore be adjusted accordingly ⇒ page 272 .  
The air conditioner compressors fitted at the start of production  
were manufactured by “Denso” (type “6 SEU 14” for vehicles  
with 4-cyl. and 6-cyl. engine and type “7 SEU 17” for vehicles  
with 8-cyl. engine); these air conditioner compressors do not  
have a magnetic clutch (they are driven continuously by the  
engine). In model year 2012, the air conditioner compressor  
type “6 SEU 14” is gradually being replaced by type  
“6 SES 14”. Air conditioner compressors produced by other  
manufacturers may also be fitted at a later date (depending on  
the engine) ⇒ Electronic parts catalogue and ⇒ Heating, air  
conditioning; Rep. gr. 87 ; Refrigerant circuit (vehicle-specific  
Workshop Manual).  
On the Audi Q5 hybrid, an electrically driven air conditioner  
compressor with integrated control electronics is installed.  
From model year 2012 onwards, air conditioner compressors  
with an additional air conditioning system magnetic clutch -  
N25- on the pulley (type “6 SAS 14”) were gradually introduced  
for vehicles with certain engines (e.g. vehicles with 4-cyl. TDI  
engine) ⇒ Heating, air conditioning; Rep. gr. 87 ; Refrigerant  
circuit (vehicle-specific Workshop Manual) and ⇒ Electronic  
parts catalogue .  
These air conditioner compressors are available as replace‐  
ment parts with different oil capacities, so it is important to pay  
attention to the oil quantity in the air conditioner compressor  
and to check the exact part number ⇒ Heating, air condition‐  
ing; Rep. gr. 87 ; Refrigerant circuit (vehicle-specific Work‐  
shop Manual) and ⇒ Electronic parts catalogue .  
The different oil quantities in the air conditioner compressor  
may result from the design of the air conditioner compressor  
(with or without oil separator at high-pressure connection) or,  
in the case of identical air conditioner compressors, from the  
design of the refrigerant circuit; pay attention to these quanti‐  
ties. Too much oil in the circuit results in higher pressures and  
a reduced cooling output of the system. Too little oil may lead  
to lubrication problems in the air conditioner compressor.  
The air conditioner compressor may have been fitted at the  
factory with a type plate indicating the part number and the  
quantity of refrigerant oil in the air conditioner compressor.  
At the start of production, air conditioner compressors with air  
conditioning system magnetic clutch - N25- and with part num‐  
ber 8T0 260 805 with index “C” were installed. The label on  
these air conditioner compressors indicates a refrigerant oil  
3
capacity of 80 +/- 10 cm . Shortly after the start of production,  
3
the refrigerant oil quantity was raised also to 110 +/- 10 cm  
for this air conditioner compressor.

Note  
The replacement compressor contains the full quantity of oil  
intended for the refrigerant circuit. If the air conditioner com‐  
pressor is renewed, the quantity of oil in the compressor must  
therefore be adjusted accordingly.  
The Audi A6 is fitted with different air conditioner compressors  
depending on the engine and production period.  
As different versions of this air conditioner compressor are  
available as replacement parts, it is important to observe the  
exact part number ⇒ Electronic parts catalogue .  
The air conditioner compressor may have been fitted at the  
factory with a type plate indicating the part number and the  
quantity of refrigerant oil in the air conditioner compressor.  
On the 10-cyl. TFSI engine (Audi RS 6), an air conditioner  
compressor with a smaller refrigerant oil capacity (70 +/ -  
3
10 cm ) than on the 10-cyl. FSI engine (Audi S6) and on other  
3
engines (130 +/ - 10 cm ) is installed due to the differing engine  
test procedure; currently the air conditioner compressors of  
the 10-cyl. FSI and 10-cyl. TFSI engines only differ in the part  
number and the refrigerant oil capacity; also refer to compres‐  
sor's label. To adjust the total quantity of oil in the refrigerant  
circuit on the 10-cyl. TFSI engine (Audi RS 6), the quantity of  
oil that is "missing" in the air conditioner compressor (60 +/ -  
3
10 cm ) is filled into the refrigerant circuit at a different location  
during production. This is not necessary during service work  
as only replacement air conditioner compressors with the orig‐  
3
inal quantity of oil (130 +/- 10 cm ) are available (this would  
only be necessary during service work if a new air conditioner  
compressor with the smaller oil capacity was being installed)

Note  
On certain versions for China the type designation 4X_ is used  
instead of 4G_.  
The replacement compressor contains the full quantity of oil  
intended for the refrigerant circuit. If the air conditioner com‐  
pressor is renewed, the quantity of oil in the compressor must  
therefore be adjusted accordingly ⇒ page 272 .  
At the start of production, all vehicles except the Audi A6 hybrid  
(and Audi A6 e-tron) were fitted with mechanically driven air  
conditioner compressors manufactured by “Denso”. Air con‐  
ditioner compressors produced by other manufacturers may  
also be fitted at a later date ⇒ Electronic parts catalogue and  
⇒ Heating, air conditioning; Rep. gr. 87 ; Refrigerant circuit  
(vehicle-specific Workshop Manual).  
At the start of production, the Audi A6 hybrid is fitted with an  
electrically driven “Denso” air conditioner compressor ( elec‐  
trical air conditioner compressor - V470- with control unit for  
air conditioning compressor - J842- ). There is no provision for  
an air conditioner compressor regulating valve - N280- on this  
air conditioner compressor.  
At the start of production, the Audi A6 e-tron is fitted with an  
electrically driven “Sanden” air conditioner compressor ( elec‐  
trical air conditioner compressor - V470- with control unit for  
air conditioning compressor - J842- ). There is no provision for  
an air conditioner compressor regulating valve - N280- on this  
air conditioner compressor.  
At the start of production, the Audi A6 hybrid was fitted with an  
air conditioner compressor with a refrigerant oil quantity of  
200 ccm. Shortly after the start of production, the refrigerant  
oil quantity was reduced to 160 ccm. The refrigerant oil does  
not have to be reduced on vehicles fitted with an air conditioner  
compressor with a refrigerant oil quantity of 200 ccm. Howev‐  
er, if the refrigerant circuit has been flushed for example, a  
total of 160 ccm should also be filled in in this vehicle as the  
specified refrigerant oil quantity. The correct amount of refrig‐  
erant oil will already be filled into a replacement air conditioner  
compressor ⇒ Electronic parts catalogue .  
From model year 2014 onwards, air conditioner compressors  
with an air conditioning system magnetic clutch - N25- fitted  
additionally at the pulley will gradually be introduced for certain  
engines and models (type “6 SES 14” or “6 SAS 14”) ⇒ Heat‐  
ing, air conditioning; Rep. gr. 87 ; Refrigerant circuit (vehicle-  
specific Workshop Manual) and ⇒ Electronic parts catalogue .  
From model year 2015 onwards, air conditioner compressors  
will gradually be introduced for which the quantity of refrigerant  
oil in the air conditioner compressor is 110 ccm (e.g. type “6  
SES 14” or “6 SAS 14”) ⇒ Heating, air conditioning; Rep. gr.  
87 ; Refrigerant circuit (vehicle-specific Workshop Manual)  
and ⇒ Electronic parts catalogue . On vehicles with such air  
conditioner compressors, the quantity of refrigerant oil in the  
refrigerant circuit is 110 ccm +20 / -10 ccm (the quantity of  
refrigerant oil stipulated for service thus remains 120 ccm +/-  
10 ccm).  
On the basis of technical product information (TPI), vehicles  
manufactured up to and including Model Year 2014 may be  
retrofitted with an air conditioner compressor of type “6 SES  
14” instead of the air conditioner compressor fitted at the fac‐  
tory. A refrigerant oil capacity of 120 ccm remains valid for  
such vehicles (if applicable, add 10 ccm of refrigerant oil after  
flushing the refrigerant circuit and installing a new air condi‐  
tioner compressor).

This air conditioner compressor is available as a replacement  
part with different oil capacities, so it is important to pay at‐  
tention to the oil quantity in the compressor and to check the  
exact part number ⇒ Heating, air conditioning; Rep. gr. 87 ;  
Refrigerant circuit (vehicle-specific Workshop Manual) and ⇒  
Electronic parts catalogue .  
The different oil quantities in the air conditioner compressor  
may result from the design of the air conditioner compressor  
(with or without oil separator at high-pressure connection) or,  
in the case of identical air conditioner compressors, from the  
design of the refrigerant circuit; pay attention to these quanti‐  
ties. Too much oil in the circuit results in higher pressures and  
a reduced cooling output of the system. Too little oil may lead  
to lubrication problems in the air conditioner compressor.  
The air conditioner compressor may have been fitted at the  
factory with a type plate indicating the part number and the  
quantity of refrigerant oil in the air conditioner compressor.

Air conditioner with refrigerant R134a - Edition 11.2018  
Note  
The replacement compressor contains a certain amount of re‐  
3
frigerant oil (currently 130 +/ - 10 cm depending on the air  
conditioner compressor, refer to label). This quantity of refrig‐  
erant oil currently corresponds to the quantity of oil specified  
for this refrigerant circuit on vehicles with one or two evapo‐  
rators (except vehicles with 8-cyl. TDI engine; for these vehi‐  
cles see below). At present, the same amount of oil is used in  
vehicles with two evaporators as in vehicles with one evapo‐  
rator. Due to the longer refrigerant lines and the second evap‐  
orator, no additional refrigerant oil is currently required in the  
refrigerant circuit on this vehicle. The refrigerant circuit on this  
vehicle is constructed so that only a small part of the refrigerant  
oil passes through the refrigerant lines to the second evapo‐  
rator and into the second evaporator when the air conditioner  
is operated. If the air conditioner compressor is renewed after  
cleaning the refrigerant circuit, it is therefore not necessary to  
pour additional refrigerant oil into the refrigerant circuit on ve‐  
hicles with two evaporators (due to the second evaporator). If  
the air conditioner compressor is renewed without having to  
clean the refrigerant circuit, the quantity of refrigerant oil in the  
new compressor to be fitted should be adjusted in line with the  
quantity of oil poured out of the old compressor ⇒ page 272 .  
On vehicles with 8-cyl. TDI engine, the quantity of refrigerant  
oil in the refrigerant circuit was increased from 130 ccm to  
180 ccm from vehicle identification number 4H_ BN 018846  
onwards. Accordingly, the refrigerant capacity thus had to be  
reduced slightly. As the capacity specification on the label has  
not yet been changed, proceed as follows: On vehicles man‐  
ufactured up to the vehicle identification number mentioned,  
check whether the refrigerant oil has already been topped up  
during a previous workshop visit. If not, add 50 ccm of refrig‐  
erant oil to the refrigerant circuit. Then correspondingly alter  
the refrigerant capacity specified on the label in waterproof ink  
and fill the refrigerant circuit with the specified quantity of re‐  
frigerant. Finally make a record of the change made in the  
vehicle data. On vehicles manufactured as of the vehicle iden‐  
tification number mentioned, check the refrigerant capacity  
specified on the label, alter accordingly in waterproof ink if ap‐  
plicable and then fill the refrigerant circuit with the specified  
quantity of refrigerant.  
Vehicles with an 8-cyl. TDI engine up to vehicle identification  
number 4H_ BN 018845 were filled at the factory with the same  
quantity of refrigerant oil as for the other engines. As of vehicle  
identification number 4H_ 018846, the refrigerant circuit on  
vehicles with an 8-cyl. TDI engine is filled at the factory with a  
larger quantity of refrigerant oil. This quantity of refrigerant oil  
applies retroactively to all vehicles with an 8-cyl. TDI engine.  
If the refrigerant circuit is re-charged on vehicles with an 8-cyl.  
TDI engine or the air conditioner compressor is renewed, e.g.  
after cleaning the refrigerant circuit, the quantity of refrigerant  
oil in the refrigerant circuit must be checked and topped up if  
necessary, or the correct quantity must be added (e.g. at open  
lines or component connections or via air conditioner service  
station prior to filling with refrigerant). If the air conditioner  
compressor is renewed without having to clean the refrigerant  
circuit, the quantity of refrigerant oil in the new compressor to  
be fitted should be adjusted in line with the quantity of oil pour‐  
ed out of the old compressor (and topped up accordingly if  
necessary on vehicles up to the vehicle identification number  
specified above) ⇒ page 272 .

The different oil quantities in the air conditioner compressor  
may result from the design of the air conditioner compressor  
(with or without oil separator at high-pressure connection) or,  
in the case of identical air conditioner compressors, from the  
design of the refrigerant circuit; pay attention to these quanti‐

As replacement air conditioner compressors with different oil  
capacities are available, it is important to observe the exact

Too much oil in the circuit results in higher pressures and a  
reduction in the cooling output of the air conditioner. Too little  
oil may lead to lubrication problems in the air conditioner com‐  
pressor. Therefore it is important to observe the specified  
refrigerant oil quantities.  
The air conditioner compressor may have been fitted at the  
factory with a type plate indicating the part number and the  
quantity of refrigerant oil in the air conditioner compressor.  
At the start of production, all vehicles except the Audi A8 hybrid  
were fitted with mechanically driven air conditioner compres‐

air conditioner compressor.  
At the start of production, the Audi A8 hybrid was fitted with an  
air conditioner compressor with a refrigerant oil quantity of  
200 ccm. Shortly after the start of production, the refrigerant  
oil quantity was reduced to 160 ccm. The refrigerant oil does  
not have to be reduced on vehicles fitted with an air conditioner  
compressor with a refrigerant oil quantity of 200 ccm. Howev‐  
er, if the refrigerant circuit has been flushed for example, a  
total of 160 ccm should also be filled in in this vehicle as the  
specified refrigerant oil quantity. The correct amount of refrig‐  
erant oil will already be filled into a replacement air conditioner  
compressor ⇒ Electronic parts catalogue .

Air conditioner with refrigerant R134a - Edition 11.2018  
Note  
The replacement compressor contains a certain amount of re‐  
3
frigerant oil (currently 140, 150 or 160 +/- 10 cm depending  
on the air conditioner compressor). This quantity of refrigerant  
oil currently corresponds to the quantity of oil specified for this  
refrigerant circuit on vehicles with one evaporator. Because of  
the longer refrigerant lines and the second evaporator, vehi‐  
cles with two evaporators require more refrigerant oil in the  
3
refrigerant circuit (currently an additional 100 cm ). If the air  
conditioner compressor is renewed after cleaning the refrig‐  
erant circuit, this quantity of refrigerant oil therefore has to be  
added to the refrigerant circuit on vehicles with two evapora‐  
tors (e.g. poured into open pipes or component connections).  
If the air conditioner compressor is renewed without having to  
clean the refrigerant circuit, the quantity of refrigerant oil in the  
new compressor to be fitted should be adjusted in line with the  
quantity of oil poured out of the old compressor ⇒ page 272 .  
As replacement air conditioner compressors with different oil  
capacities are available, it is important to observe the exact  
part number ⇒ Electronic parts catalogue .  
The different oil quantities in the air conditioner compressor  
may result from the design of the air conditioner compressor  
(with or without oil separator at high-pressure connection) or,  
in the case of identical air conditioner compressors, from the  
design of the refrigerant circuit; pay attention to these quanti‐  
ties. Too much oil in the circuit results in higher pressures and  
a reduced cooling output of the system. Too little oil may lead  
to lubrication problems in the air conditioner compressor.  
The air conditioner compressor may have been fitted at the  
factory with a type plate indicating the part number and the  
quantity of refrigerant oil in the air conditioner compressor.

Air conditioner with refrigerant R134a - Edition 11.2018  
Note  
The replacement compressor contains the full quantity of oil  
intended for the refrigerant circuit. If the air conditioner com‐  
pressor is renewed, the quantity of oil in the compressor must  
therefore be adjusted accordingly ⇒ page 272 .  
As replacement air conditioner compressors with different oil  
capacities are available, it is important to observe the exact  
part number ⇒ Electronic parts catalogue .  
From vehicle identification number 429 DN 000751 onwards  
(manufactured from 11.2013), the quantity of refrigerant in the  
circuit was increased from 650 g to 680 g and the quantity of  
refrigerant oil from 150 ccm to 200 ccm. The increased amount  
of refrigerant and refrigerant oil also applies to all earlier ve‐  
hicles. On vehicles manufactured up to the vehicle identifica‐  
tion number mentioned, check whether the refrigerant oil has  
already been topped up during a previous workshop visit. If  
not, add 50 ccm of refrigerant oil to the refrigerant circuit. Then  
check the refrigerant capacity indicated on the label and if  
necessary attach a new label with the correct capacity and the  
appropriate language (e.g. the label with part number  
420 010 535 and index BA in German and English) ⇒ Elec‐  
tronic parts catalogue and ⇒ Heating, air conditioning; Rep.  
gr. 87 ; Installation location overview - Air conditioning (vehi‐  
cle-specific Workshop Manual). If no label with the correct  
capacity and the appropriate language is available, alter the  
capacity indicated on the existing label accordingly with a wa‐  
terproof pen. Then increase the refrigerant oil quantity in the  
refrigerant circuit by 50 ccm and charge the refrigerant circuit  
with the quantity of refrigerant shown above  
⇒ “10.1.23 Capacities for Audi R8 (42_) 2008 ►, Audi R8 (4S_)  
2015 ►”, page 332 .  
The air conditioner compressor may have been fitted at the  
factory with a type plate indicating the part number and the  
quantity of refrigerant oil in the compressor (on the Audi R8  
this type plate is not visible when the compressor is installed).  
On vehicles up to the vehicle identification number quoted  
above, where the air conditioner compressor was filled with a  
smaller quantity of refrigerant oil at the factory, make a note in  
the vehicle documentation (and on the label indicating the re‐  
frigerant capacity) to show that the quantity of refrigerant oil  
has already been increased by 50 ccm in the workshop.  
The different oil quantities in the air conditioner compressor  
may result from the design of the air conditioner compressor  
(with or without oil separator at high-pressure connection) or,  
in the case of identical air conditioner compressors, from the  
design of the refrigerant circuit; pay attention to these quanti‐  
ties. Too much oil in the refrigerant circuit results in higher  
pressures and a reduction in the cooling output of the air con‐  
ditioner. Too little oil may lead to lubrication problems in the  
air conditioner compressor. Therefore it is important to ob‐  
serve the specified refrigerant oil quantities.
