Capacities for refrigerant R134a

•

On vehicles from Audi A8 (4N) 2018 onwards, the capacity for

refrigerant R134a can be found in the vehicle-specific Work‐

shop Manual ⇒ Heating, air conditioning; Rep. gr. 00 ;

Technical data .

Note

♦ When charging the high-pressure side of refrigerant circuits,

always fill to the upper tolerance limit (some liquid refrigerant

will remain in the filler hoses).

♦ Unless otherwise stated, the capacities specified for refriger‐

ant R134a also apply to the S and RS versions of this vehicle

model.

♦ When charging the refrigerant circuit, the air conditioner serv‐

ice station must be on the same level as the vehicle in which

the refrigerant circuit is to be charged (maximum difference 50

cm). Depending on the design of the air conditioner service

station , an excessive difference in height could lead to differ‐

ences between the quantity of refrigerant displayed and that

actually poured in. The charging accuracy of the air condition‐

er service station may change.

♦ For the assignment of the air conditioner compressor (“Zexel/

Valeo”, “Sanden” or “Denso/Nippondenso”), refer to ⇒ Elec‐

tronic parts catalogue and ⇒ Heating, air conditioning; Rep.

gr. 87 ; Refrigerant circuit (vehicle-specific Workshop Man‐

ual).

♦ Refrigerant circuits converted from R12 to R134a are to be

filled with the quantity indicated in the Workshop Manual “Air

conditioner with refrigerant R12”. ⇒ Air conditioning system

with refrigerant R12 (this Workshop Manual is only available

in hardcopy form).

♦ 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).

Air conditioner with refrigerant R134a - Edition 11.2018

Note

♦ Various air conditioner compressors have been fitted depend‐

ing on the production period and engine (these air conditioner

compressors have no magnetic clutch).

♦ 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” air conditioner compres‐

sors (type “6 CVC 140”) may also be fitted at a later date

(introduction not yet finalised, planned from 09.12 onwards);

see ⇒ Electronic parts catalogue and ⇒ Heating, air condi‐

tioning; Rep. gr. 87 ; Refrigerant circuit (vehicle-specific Work‐

shop Manual).

♦ As of 11.2012, the quantity of refrigerant oil for the “Denso” air

conditioner compressor with part number “5Q0 xxx xxx” was

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 manufactured with this

air conditioner compressor up to 11.2012, check whether the

quantity of refrigerant oil has already been increased during a

previous workshop visit. If not, add 30 ccm of refrigerant oil to

the refrigerant circuit

⇒ “10.2.3 Capacities for Audi A1 (8X_) 2011 ►”, page 338 .

Then enter the refrigerant oil capacity on the label in water‐

proof ink ⇒ Heating, air conditioning; Rep. gr. 87 ; Installation

location overview - Air conditioning (vehicle-specific Work‐

shop Manual) and fill the refrigerant circuit with the quantity of

refrigerant indicated above.

♦ From 06.14 onwards, the evaporator, expansion valve and the

corresponding refrigerant lines have been modified (different

lines, attachment points etc.). In the period from 06.14 to

11.14, these air conditioners were still filled with 500 grams of

refrigerant at the factory. From 11.14 onwards, the amount of

refrigerant was reduced from 500 grams to 475 grams. Rea‐

son: In unfavourable ambient conditions (high ambient tem‐

peratures, dirt in condenser etc.), adding 500 grams of

refrigerant may lead to excessive pressures in the refrigerant

circuit on these vehicles. On vehicles built within this period,

check the refrigerant capacity indicated on the label and cor‐

rect it if necessary to 475 grams with a waterproof pen (or

renew the label) ⇒ Heating, air conditioning; Rep. gr. 87 ;

♦ Depending on manufacturer, colour of red restrictor may tend

more towards orange.

♦ To avoid altering the cooling output of the air conditioner, re‐

strictors with the same hole diameter must always be used.

♦ A restrictor with a smaller hole (red-coloured) and a condenser

with a smaller internal volume are installed from model year

2002 onwards. The capacity has therefore been slightly modi‐

fied (condenser -70 g, smaller restrictor +50 g) ⇒ Heating, air

♦ If no replacement condenser with a flat tube width = 20 mm is

available for an Audi A3, and a condenser with a flat tube width

= 16 mm is fitted, only 650 +/- 20 g of refrigerant may be added

(instead of 750 + 50 g). In addition the capacity given on the

label must be altered accordingly (observe notes on Audi TT

⇒ page 297 ).

♦ The logo of the compressor manufacturer “Zexel” attached to

Note

♦ Exclusive use was made at the start of production of “Sanden”

“Zexel/Valeo” air conditioner compressors have also been

used ⇒ Heating, air conditioning; Rep. gr. 87 ; Refrigerant

circuit (vehicle-specific Workshop Manual) and ⇒ Electronic

parts catalogue .

♦ The air conditioner compressor designation “Zexel / Valeo”

was changed as of 2006 to “Valeo”.

♦ With effect from 10.03 (as of vehicle identification number

8N41015239), production of the Audi TT was switched from

the condenser with part no. “1J0 820 411 J” (with a flat tube

width of 20 mm) to the condenser with part no. “8N0 820 411

A” (with a flat tube width of 16 mm) ⇒ page 297 . In the period

between 06.04 and 08.04, a certain number of vehicles was

again fitted with condensers with a flat tube width of 20 mm.

♦ Condensers with a flat tube width = 16 mm must be filled with

approx. 120 g less refrigerant than condensers with a flat tube

width = 20 mm ⇒ Electronic parts catalogue .

♦ In the period between 10.03 (vehicles as of vehicle identifica‐

tion number 8N41015239) and 06.04, the Audi TT was fitted

at the factory with a condenser with a flat tube width of 16 mm

(part no. “8N0 820 411 A”) and the refrigerant circuit filled with

750 + 50 grams of refrigerant. These vehicles were also pro‐

vided with a sticker showing the incorrect capacity - namely

750 grams (or 700 grams in 06.04) instead of 650 grams

⇒ page 297 . Under certain ambient conditions (e.g. high am‐

bient temperatures), over-filling of the systems may result in

the air conditioner compressor being shut off on account of

excess pressure in the refrigerant circuit. Complaints may also

be received about engine performance (e.g. humming and

drumming; the engine is subjected to greater load as the air

conditioner compressor constantly has to cope with exces‐

sively high pressure). Remedy: Discharge the refrigerant cir‐

cuit, then re-charge with the correct quantity and replace the

label with a label indicating the correct capacity or delete the

old capacity indicated on the label and enter the new capacity

in waterproof ink for example.

♦ Pay attention to flat tube dimensions if condenser is renewed.

If a condenser with different flat tube dimensions is to be fitted,

also replace the label indicating the refrigerant R134a capacity

or delete the old capacity and enter the new capacity in wa‐

terproof ink for example ⇒ Electronic parts catalogue .

Air conditioner with refrigerant R134a - Edition 11.2018

Note

♦ Restrictors with a modified hole have been installed at the fac‐

tory since November 1997 (yellow-coloured). The capacity

was increased by 50 g for vehicles with a yellow-coloured re‐

strictor.

♦ In order to distinguish between the two restrictor versions, the

one with the smaller hole (1.54 mm) is yellow-coloured. The

restrictor with the larger hole (1.83 mm) is not coloured.

♦ The Audi A4 was fitted with different air conditioner compres‐

sors depending on the engine and production period. Exclu‐

sive use was made at the start of production of “Zexel / Valeo”

air conditioner compressors. As of Model Year 1996, “Denso”

air conditioner compressors were gradually introduced for ve‐

hicles with 6-cylinder engines.

♦ 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).

♦ Replacement restrictors with different holes (not coloured, yel‐

low-coloured, red-coloured) are available. If a vehicle is fitted

with a different restrictor, add more or less refrigerant depend‐

ing on type (⇒ Table). After charging, amend capacity stated

on label or affix label indicating new capacity.

♦ Depending on manufacturer, colour of red restrictor may tend

more towards orange.

♦ From November 1998 onwards, Audi A4 models have also

been fitted with “AWG” condensers (initially approx. 10000

vehicles with chassis numbers between 8DXA 065 253 and

8DXA 077 026). The specified capacity for vehicles with these

condensers differs from those with “Showa/ Keihin” condens‐

ers. The condensers can be identified on the basis of certain

characteristic features ⇒ page 304 .

♦ If the condenser installed is replaced by one with a different

part number, check the capacity indicated on the label in the

vehicle and amend if necessary or affix a label with the correct

capacity over the existing one ⇒ Heating, air conditioning;

Note

♦ Replacement restrictors with different holes are available (yel‐

low-coloured 1.54 mm, red-coloured 1.42 mm).

♦ Depending on manufacturer, colour of red restrictor may tend

more towards orange.

♦ To avoid altering the cooling output of the air conditioner, only

red or yellow-coloured restrictors are to be fitted. Yellow-col‐

oured restrictors were fitted in model year 2001. Red-coloured

restrictors were introduced in model year 2002. The change

to the restrictor (on vehicles produced in model year 2001, a

red-coloured restrictor may also be fitted instead of a yellow-

coloured one) does not alter the capacity for these vehicles.

♦ Various air conditioner compressors have been fitted depend‐

ing on the production period and engine (these air conditioner

compressors have no magnetic clutch).

♦ At the start of production exclusive use was made of type “6

SEU 12” and “7 SEU 16” air conditioner compressors from

“Denso”. From model year 2004 onwards, different “Denso”

compressors (types “6 SEU 14” and “7 SEU 17”) have gradu‐

ally replaced the old ones ⇒ Heating, air conditioning; Rep.

gr. 87 ; Refrigerant circuit (vehicle-specific Workshop Manual)

and ⇒ Electronic parts catalogue .

♦ The Audi RS 4 is fitted with a condenser with a smaller internal

volume. The capacity for this vehicle is therefore lower than

for the other vehicles ⇒ Electronic parts catalogue .

Note

♦ Starting with the product changeover in March 2012, Audi A4

and Audi A5 vehicles (except RS models) are no longer avail‐

able with 8-cyl. engines.

♦ 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).

♦ 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 .

♦ From August 2011 onwards, air conditioners with air condi‐

tioning system magnetic clutch - N25- are gradually being

introduced for certain 4-cyl. TDI engines ⇒ Electronic parts

catalogue .

♦ From March 2012 onwards, the refrigerant circuit (air condi‐

tioner compressor, condenser, evaporator etc.) was gradually

modified depending on the engine. This means that the refrig‐

erant and refrigerant oil capacity for these vehicles has also

changed (indicated on label for refrigerant circuit)

⇒ page 352 ⇒ Heating, air conditioning; Rep. gr. 87 ; Re‐

frigerant circuit (vehicle-specific Workshop Manual) and ⇒

Electronic parts catalogue .

♦ From June 2012 onwards, condensers manufactured by

“Showa / Keihin” (part number 8KD xxx xxx) are gradually be‐

ing installed on vehicles produced in China. This condenser

has a different internal design, thus resulting in a different re‐

frigerant capacity. Identification ⇒ page 316

♦ From October 2013 onwards, condensers manufactured by

“Showa/Keihin” with part number 8T0 xxx xxx and index “D” or

later are gradually being installed in all vehicles (apart from the

RS models). This condenser has a different structure (flat

tubes are not as high (1.5 mm instead of 2.0 mm), therefore

the internal volume is smaller) than the condenser manufac‐

tured by “Showa/Keihin” with part number 8T0 xxx xxx and

index “C” or earlier, therefore the refrigerant capacity is also

different. Identification ⇒ page 316

♦ If a condenser manufactured by “Showa/Keihin” with part

number 8T0 xxx xxx and index “D” or later or a condenser

manufactured by “Denso” is installed in a vehicle in which a

condenser manufactured by “Showa/Keihin” with part number

8T0 xxx xxx and index “C” or earlier (or a condenser with part

number 8K0 xxx xxx or 8KD xxx xxx) was previously installed,

then the capacity valid for this condenser must be added (see

table). The same applies if a condenser manufactured by

“Denso” is replaced with a condenser with a different manu‐

facturer or part number. In addition, the capacity specified on

the label in the vehicle is to be checked and amended if nec‐

essary or the existing label is to be replaced with one indicating

the correct capacity (affix over old label).

engine) ⇒ Heating, air conditioning; Rep. gr. 87 ; Refrigerant

circuit (vehicle-specific Workshop Manual) and ⇒ Electronic

parts catalogue .

♦ From August 2011 onwards, air conditioners with air condi‐

tioning system magnetic clutch - N25- are gradually being

introduced for certain 4-cyl. TDI engines ⇒ Electronic parts

catalogue .

♦ From June 2012 onwards, the refrigerant circuit (air condition‐

er compressor, condenser, evaporator etc.) was gradually

modified depending on the engine. This means that the refrig‐

erant and refrigerant oil capacity for these vehicles has also

changed (indicated on label for refrigerant circuit) ⇒ Heating,

air conditioning; Rep. gr. 87 ; Refrigerant circuit (vehicle-spe‐

cific Workshop Manual) and ⇒ Electronic parts catalogue .

♦ From June 2012 onwards, condensers manufactured by

“Showa/Keihin” (part number 8KD xxx xxx) are gradually being

installed on vehicles produced in China. This condenser has

a different internal design, thus resulting in a different refrig‐

erant capacity. Identification ⇒ page 316

♦ From October 2013 onwards, condensers manufactured by

“Showa/Keihin” with part number 8T0 xxx xxx and index “D” or

later are gradually being installed in all vehicles (apart from the

RS models). This condenser has a different structure (flat

tubes are not as high (1.5 mm instead of 2.0 mm), therefore

the internal volume is smaller) than the condenser manufac‐

tured by “Showa/Keihin” with part number 8T0 xxx xxx and

index “C” or earlier, therefore the refrigerant capacity is also

different. Identification ⇒ page 316

♦ If a condenser manufactured by “Showa/Keihin” with part

number 8T0 xxx xxx and index “D” or later or a condenser

manufactured by “Denso” is installed in a vehicle in which a

condenser manufactured by “Showa/Keihin” with part number

8T0 xxx xxx and index “C” or earlier (or a condenser with part

number 8K0 xxx xxx or 8KD xxx xxx) was previously installed,

then the capacity valid for this condenser must be added (see

table). The same applies if a condenser manufactured by

“Denso” is replaced with a condenser with a different manu‐

facturer or part number. In addition, the capacity specified on

the label in the vehicle is to be checked and amended if nec‐

essary or the existing label is to be replaced with one indicating

the correct capacity (affix over old label).

♦ 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) ⇒ page 316 and ⇒ Electronic parts

catalogue .

Air conditioner with refrigerant R134a - Edition 11.2018

♦ 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.

♦ From October 2013 onwards, the refrigerant quantity for the

refrigerant circuit on the Audi Q5 Hybrid was increased from

840 g to 900 g. The increased quantity of refrigerant applies

retroactively to all vehicles from July 2012 onwards with an

operating and display unit for the air conditioning, the control

unit for Climatronic - J255- with part number 8Kx xxx xxx and

an air conditioning unit with part number 8Tx xxx xxx (different

software and different evaporator in the air conditioning unit)

with the next filling. The refrigerant circuit does not have to be

specially emptied to fill it with the increased quantity. It is

enough to pour in the increased quantity e.g. after performing

an operation on the refrigerant circuit for which emptying and

refilling is required anyway. On vehicles manufactured up to

October 2013, check whether the increased quantity of refrig‐

erant has already been added during a previous workshop visit

and the indicated capacity on the label has been changed. If

not, check the refrigerant capacity on the label and if neces‐

sary stick on a new label with the correct capacity and lan‐

guage ⇒ Electronic parts catalogue and ⇒ Heating, air

conditioning; Rep. gr. 87 ; Installation location overview - Air

conditioning (vehicle-specific Workshop Manual). If no label

with the correct capacity and the appropriate language is avail‐

able, alter the capacity indicated on the existing label accord‐

ingly with a waterproof pen. If necessary, subsequently fill the

refrigerant circuit with the higher refrigerant quantity indicated

above.

Note

♦ The air conditioner compressors fitted at the start of production

were manufactured by “Denso” (type “7 SEU 17”); these air

conditioner compressors do not have a magnetic clutch (they

are driven continuously by the engine via a shaft). Air condi‐

tioner 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

♦ On the Audi RS 4 and RS 5 there is no changeover of the

refrigerant circuit in model year 2012 (see other versions).

Distinguishing features of condensers

Note

♦ Different condensers are installed in these vehicles depending

on the production period, vehicle version and engine ⇒ Elec‐

tronic parts catalogue . The distinguishing features of these

condensers are the internal design and the internal volume.

This means that the capacity of the refrigerant circuit varies

depending on the condenser. Therefore it is important to ob‐

serve the version of the condenser when determining the

refrigerant capacity.

♦ Currently condensers by different manufacturers (“Denso” and

“Showa/Keihin”) are installed; they can be identified by certain

features.

♦ The design of condensers by one manufacturer can also vary;

from the outside this can only be identified by the part number.

Due to the differences in design (flow distribution, internal vol‐

ume), the refrigerant capacity for the refrigerant circuit varies

⇒ page 36 .

♦ These condensers are available in different versions with dif‐

ferent designs (can be identified e.g. by part numbers

8K0 xxx xxx , 8Rx xxx xxx, 8KD xxx xxx or 8T0 xxx xxx)

⇒ page 36 ; for the correct version refer to the ⇒ Electronic

Note

From October 2013 onwards, condensers manufactured by

“Showa/Keihin” with part number 8T0 xxx xxx and index “D” or

later are gradually being installed in all vehicles (apart from the

are not as high (1.5 mm instead of 2.0 mm), therefore the internal

volume is smaller) than the condenser manufactured by “Showa/

Keihin” with part number 8T0 xxx xxx and index “C” or earlier,

therefore the refrigerant capacity is also different. The only way

to tell these condensers apart is by the part number; there is no

way to unambiguously determine the different flat tube heights

using workshop equipment.

Note

♦ If a vehicle is fitted with a yellow-coloured restrictor as re‐

placement for a non-coloured restrictor, add 50 g more refrig‐

erant than specified in the table. In addition, the capacity

specified on the label in the vehicle is to be checked and

amended if necessary or the existing label is to be replaced

with one indicating the correct capacity (affix over old label).

♦ Restrictors with modified hole (coloured) have been installed

at the factory since November 1997. In order to distinguish

between the two restrictor versions, the one with the smaller

hole (1.54 mm) is yellow-coloured. The restrictor with the larg‐

er hole (1.83 mm) is not coloured.

♦ The Audi 100 / Audi A6 features different air conditioner com‐

pressors depending on the engine and production period.

Exclusive use was made at the start of production of “Zexel /

Valeo” air conditioner compressors. As of Model Year 1996,

“Denso” air conditioner compressors were gradually intro‐

duced for vehicles with 6-cylinder engines.

♦ The air conditioner compressor designation “Zexel / Valeo”

was changed as of 2006 to “Valeo”.

♦ From September 1994, production was gradually switched

from condenser 4A0 260 403 AB to condenser 4A0 260 403

AC.

♦ The refrigerant capacity of 750+50 g applies to all Audi 100

models (regardless of condenser).

♦ Only condensers with part number 4A0 260 403 AC are now

available as replacement parts (if necessary make use of la‐

bel, part no. 8A0 010 126 P).

♦ After charging the refrigerant circuit of vehicles manufactured

up to October 1994, check the capacity stated on the label in

the vehicle and amend if necessary or affix the label, part no.

was increased by 50 g for vehicles in which a yellow-coloured

restrictor was installed.

♦ In order to distinguish between the two restrictor versions, the

one with the smaller hole (1.54 mm) is yellow-coloured. The

restrictor with the larger hole (1.83 mm) is not coloured.

♦ If a vehicle is fitted with a coloured restrictor as replacement

for a non-coloured restrictor, add 50 g more refrigerant (see

table). In addition, the capacity specified on the label in the

vehicle is to be checked and amended if necessary or the ex‐

isting label is to be replaced with one indicating the correct

capacity (affix over old label).

♦ The Audi A6 is fitted with different air conditioner compressors

depending on the engine and production period.

♦ In August/September 1998, production was gradually switch‐

ed from air conditioning unit version “1” to air conditioning unit

version “2”. A reduction in capacity was achieved as the evap‐

orator was also modified together with the air conditioning unit.

♦ The two air conditioning unit versions can be identified on the

basis of certain characteristics described in the vehicle-spe‐

cific Workshop Manual ⇒ Heating, air conditioning; Rep. gr.

87 ; Installation location overview - Air conditioning (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).

The capacity is different for vehicles with these condensers.

The condensers can be identified on the basis of certain char‐

acteristics and the part number ⇒ page 324 .

♦ The Audi A6 is fitted with different air conditioner compressors

depending on the engine and production period.

♦ When renewing a condenser, pay attention to the index of the

part number (different flat tube versions, flat tube dimensions

16 mm x 1.7 mm, 18 mm x 1.7 mm or 20 mm x 3 mm) and the

different capacities. If a condenser with a different part number

index is installed, the capacity specified on the label must be

checked and amended if necessary or a label indicating the

modified capacity must be affixed over the existing label. The

part number can be found on a sticker attached to the bottom

of the condenser.

♦ From 04.99 onwards, production was gradually switched from

condensers with flat tube dimensions 20 mm x 3 mm to con‐

densers with flat tube dimensions 18 mm x 1.7 mm or 16 mm

x 1.7 mm. The change in production took place gradually dur‐

ing the course of 1999 depending on the engine and existing

supplies of the different versions. Refer to the Electronic parts

catalogue for precise assignment of the different condensers

Note

♦ On certain versions for China the type designation 4X_ is used

instead of 4G_.

♦ At the start of production, all vehicles except the Audi A6 hybrid

(Audi A6 e-tron) were fitted with mechanically driven air con‐

ditioner compressors manufactured by “Denso”. Air condition‐

er compressors produced by other manufacturers may also be

fitted at a later date ⇒ Electronic parts catalogue and ⇒ Heat‐

ing, 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. A capacity of 840 +/- 15 g for refrigerant was planned

at the factory for these vehicles (specification on label for re‐

frigerant). Shortly after the start of production, the refrigerant

oil quantity was reduced to 160 ccm and the refrigerant quan‐

tity was raised to 860 +/- 15 g. In after-sales service, a quantity

of 860 +/- 15 g of refrigerant always applies for this vehicle

irrespective of the refrigerant oil quantity (if necessary, change

capacity specification on label with a water-proof pen).

♦ In contrast to vehicles with other engines, on Audi RS 6 / RS

7 a condenser with a smaller internal volume is installed;

therefore the refrigerant capacity for these vehicles is slightly

lower than for other vehicles in this series ⇒ Electronic parts

catalogue .

Note

♦ Restrictors with a modified hole have been installed at the fac‐

tory since November 1997 (yellow-coloured). The capacity

was increased by 50 g for vehicles with a yellow-coloured re‐

strictor.

♦ In order to distinguish between the different restrictor versions,

the one with the smaller hole is coloured yellow (1.54 mm) or

red (1.42 mm). The restrictor with the larger hole (1.83 mm) is

not coloured.

♦ If a vehicle is fitted with a yellow-coloured restrictor as re‐

placement for a non-coloured restrictor, add 50 g more refrig‐

erant (see table). In addition, the capacity specified on the

label in the vehicle is to be checked and amended if necessary

or the existing label is to be replaced with one indicating the

correct capacity (affix over old label). The red-coloured re‐

strictor is not to be used for these vehicles.

♦ Exclusive use was made at the start of production of “Zexel /

Valeo” air conditioner compressors. From model year 1996

onwards, production was gradually switched to “Denso” air

conditioner compressors ⇒ Heating, air conditioning; Rep. gr.

Note

♦ For vehicles with 8-cyl. TDI engine, the quantity of refrigerant

oil in the refrigerant circuit was increased as of vehicle identi‐

fication number 4H_ BN 018846 and the refrigerant capacity

had to be accordingly reduced slightly. As the capacity spec‐

ification on the label has not yet been changed, proceed as

follows: On vehicles manufactured up to the vehicle identifi‐

cation 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 correspondingly alter the refrigerant capacity specified

on the label in waterproof ink and fill the refrigerant circuit with

the quantity of refrigerant stated above. Finally make a record

of the change made in the vehicle data. On vehicles manu‐

factured as of the vehicle identification number mentioned,

check the refrigerant capacity specified on the label, alter ac‐

cordingly in waterproof ink if applicable and then fill the refrig‐

erant circuit with the quantity of refrigerant specified above.

♦ At the start of production, all vehicles except the Audi A8 hybrid

were fitted with mechanically driven air conditioner compres‐

sors manufactured by “Denso”. Air conditioner compressors

produced by other manufacturers may also be fitted at a later

date ⇒ Electronic parts catalogue and ⇒ Heating, air condi‐

tioning; Rep. gr. 87 ; Refrigerant circuit (vehicle-specific Work‐
