Checking and topping up fluids

If you have to top up the engine oil, use one of

the oils that meet the engine oil standard speci-

fied on the sticker ðFig. 127. The sticker with

the specified standard is located at the front of

the engine compartment ðpage 237, Fig. 126. If

you use this oil, you can top up the engine oil lev-

el as often as necessary.

– If the engine oil level is too low, add more oil

ðpage 239. Do not drive on until the warning

lamp has gone out.

– If the engine oil level is OK but the warning

lamp still lights up, switch off the engine and

do not drive on. Seek professional assistance.



Please add oil immediately

If the specified engine oil is not available, you can

add a maximum of 0.5 litres of oil corresponding

to the following standards once between oil

changes. You should do this in emergencies only.

Switch off the engine and do not drive on. Check

the oil level ðpage 239 and top it up immediate-

ly ðpage 239.



Please add max. x ltr. oil. You can continue

– Applies to petrol engines: Standards:

VW 504 00, ACEA C3, ACEA C4, API SP or ILSAC

GF-6A. All viscosity classes of these standards

are allowed.

driving

Add the amount of oil shown soon ðpage 239.



Please reduce oil level

– Applies to diesel engines: Standards:

VW 507 00, ACEA C3, ACEA C4 or API CK-4. All

viscosity classes of these standards are al-

lowed.

The engine contains too much oil – risk of dam-

age to the catalytic converter and engine. Drive

to a qualified workshop without delay to have the

engine oil level adjusted if necessary. Avoid high

engine speeds, full acceleration and heavy engine

loads.

Audi recommends having the oil changed by a

qualified workshop.

Audi recommends engine oil from Audi Genuine

Parts.



Oil level sensor system: fault. Please contact

workshop

The sensor for checking the engine oil level has

failed. Drive to a qualified workshop soon and

have the fault rectified.

CAUTION

Audi recommends that you use the types of

engine oil that have been formulated to con-

form to the corresponding VW standard. Us-

ing engine oil that does not meet these quali-

ty requirements may cause damage to the en-

gine. In an emergency, 0.5 ltr. of engine oil

corresponding to the standards specified

above may be used as an exception.



Oil system: fault. Please contact workshop

The sensor for checking the engine oil pressure or

the bonnet lock has failed. Drive to a qualified

workshop soon and have the fault rectified.



Please warm up engine

It is possible for fuel to enter the engine oil, es-

pecially at low outside temperatures. The tem-

perature of the engine oil needs to be high

enough so that the fuel in it can evaporate.

Driver messages about the engine oil

system

The following driver messages may appear, de-

pending on the equipment installed in your vehi-

cle:

Drive in transmission position S.

Run the engine at high rpm speeds but avoid us-

ing full throttle.



Switch off engine. Oil pressure too low

Switch off the engine and do not drive on. Check

the engine oil level ðpage 239.

You should drive for at least 30 minutes; however

it is possible that the indicator lamp may not go

out during this period. Repeat the procedure at

your convenience.



Checking and topping up fluids

If the indicator lamp does not disappear after

several runs, drive to a qualified workshop and

have the fault rectified.

– Park the vehicle on a level surface.

– Switch off the warm engine.

– Switch on the ignition again without starting

the engine.

WARNING

– Wait for about 5 minutes for the engine oil to

drain back out of the engine into the sump.

– You can call up the engine oil level via the Car

menu ðpage 26.

When responding to the message  Please

warm up engine, it is essential that you ad-

just your speed to suit the weather, road, ter-

rain and traffic conditions – risk of accident!

The recommendation must never lead to the

driver disregarding local traffic regulations.

– Read off the oil level on the display.

Information on the oil level display

The oil level shown on the centre display (MMI) is

intended solely for information purposes. An oil

will appear in the instru-

ment cluster if the oil level is too low. Add more

oil ðpage 239, Topping up the engine oil.

Information on engine oil consumption

Depending on how you drive and the conditions

in which the car is used, oil consumption can be

up to 0.5 ltr./1000 km. Oil consumption is likely

to be higher for the first 5,000 km. The engine

oil level must be checked at regular intervals,

preferably when refuelling and before a journey.

Fig. 128 Centre display: Checking engine oil level

Areas of the oil level display ðFig. 128. Please

refer to ð

CAUTION

If the display is in this area, the engine oil

level is correct.

There is a risk of engine damage if the engine

oil level is too low or too high.

If the display is in this area, you could top up

the engine oil.

Topping up the engine oil

If the display is in this area, you must top up

the engine oil.

The engine oil level should be inside the top per-

missible area when the vehicle is subject to par-

ticularly high loads, such as during long motor-

way trips in the summer or when driving over

mountain passes.

Checking the engine oil level in the MMI

You can check the engine oil level on the MMI.

Coolant additive

ðpage 239, Checking the engine oil level.

Applies when using engine oil that corresponds

to the specified standard: Add a little more en-

gine oil if necessary.

The coolant additive contains anti-freeze and cor-

rosion protection agent. When topping up, use

only the type of coolant additive specified below,

in combination with distilled water.

►

Coolant additive

G12evo

Specification

TL 774 L

WARNING

– Ensure that no oil comes into contact with

hot engine components when topping up:

this could cause a fire.

The amount of coolant additive which needs to

be mixed with the water depends on the temper-

atures to be expected in the winter season. If the

anti-freeze concentration is too low, the coolant

can freeze and cause engine damage.

– The oil filler cap must be properly closed to

prevent oil from squirting onto the hot en-

gine or exhaust system while the engine is

running – risk of fire!

Frost protec-

tion

– Wash your skin thoroughly if it comes into

– Engine oil is poisonous and must be kept out

of the reach of children.

CAUTION

No additives should be used with engine oil.

These could cause engine damage.

– Have your qualified workshop check the

cooling system before the winter season to

make sure that the anti-freeze concentra-

tion is adequate for the conditions to be ex-

pected. This applies particularly if you drive

into a colder climate zone.

For the sake of the environment

– Never pour oil down drains or into the

ground.

– Always observe local regulations when dis-

posing of empty oil canisters.

– Adjustments to the amount of coolant addi-

tive to suit colder temperatures must al-

ways be carried out by a qualified workshop;

otherwise there is a risk of engine damage.

The vehicle has several coolant circuits that

can only be filled by a qualified workshop

that has the necessary special tools.
