Checking and Filling

Adding engine oil

Tips

The engine oil consumption may be up to

0.5 quart/600 miles (0.5 liter/1,000 km), de-

pending on driving style and operating condi-

tions. Consumption may be higher during the

first 3,000 miles (5,000 km). The engine oil

level must be checked regularly. It is best to

check each time you refuel your vehicle and

before long drives.

– Because of the lubrication and cooling of

the engine, combustion engines consume

oil. The oil consumption varies depending

on the engine and may change during the

service life of the engine. Engines generally

consume more oil at the beginning during

the break-in period. Then oil consumption

stabilizes after the break-in period.

Observe the safety precautions ðpage 250, Gen-

eral information.

►

Turn off the engine.

►

Open the hood ðpage 252.

– Under normal conditions, oil consumption

depends on the quality and viscosity of the

oil, the engine RPM, the climate conditions,

and the road conditions. The dilution of oil

from condensation or fuel residue as well as

the age of the oil also play a role. Because

engine wear increases with mileage, oil con-

sumption will increase again over time until

it may be necessary to replace worn compo-

nents.

►

Unscrew the cap  for the engine oil filler

opening ðfig. 170.

Carefully add 0.5 quart (0.5 liter) of the correct

oil ðpage 254.

Close the engine oil filler opening cap.

Close the hood ðpage 252.

Restart the ignition after two minutes and read

the current oil level in the MMI ðpage 255.

►

Applies to: using engine oil that meets the rec-

ommended specification: Add some more en-

gine oil again if necessary.

– Because all these variables play a role, it is

not possible to define an oil consumption

standard. Therefore, the oil level must be

checked regularly.

WARNING

– When adding oil, do not let oil drip onto hot

engine components. This increases the risk

of a fire.

– If you believe that your engine has increased

its oil consumption, contact an authorized

Audi dealer or authorized Audi Service Fa-

cility to determine the cause. Please note

that an exact oil consumption measurement

must be done with the necessary care and

accuracy and may take time. An authorized

Audi dealer or authorized Audi Service Fa-

cility is trained in accurately measuring the

oil consumption.

– You must close the cap on the oil filler open-

ing correctly so that oil does not leak out on-

to the hot engine and exhaust system when

the engine is running, because this is a fire

hazard.

– Always clean skin thoroughly if it comes into

contact with engine oil.

– Engine oil is poisonous and must be kept out

of reach of children.

– You can find information on engine oil and

engine oil capacities for the USA at

or for Can-

– Store the engine oil securely in the original

container.

Checking and Filling

If you change the engine oil yourself, please note

the following important information:

Note

– Only use high-grade engine oil that explicit-

ly meets the Audi oil quality standard for

your vehicle. Using another oil may cause

severe vehicle damage.

WARNING

If you change the engine oil on the vehicle

yourself, the following precautions must be

followed:

– Do not mix any additives with the engine oil.

Additives may cause engine damage that is

not covered by your New Vehicle Limited

Warranty.

– Wear protective eyewear.

– Due to the risk of scalding, allow the engine

to cool down sufficiently.

– Maintain enough distance when you are re-

moving the oil drain plug. While doing this,

keep your forearm parallel to the ground to

reduce the risk of hot oil dripping down your

arm.

For the sake of the environment

– Oil should never enter the sewer system or

come into contact with the ground.

– Follow the legal regulations in the country

where you are located when disposing of

empty oil containers.

– Drain the oil into a container designed for

this purpose that is large enough to hold the

full amount of oil in your engine.

– Engine oil is poisonous. Always store out of

reach of children.

Changing engine oil

Audi recommends having the oil changed at an

authorized Audi dealer or authorized Audi Serv-

ice Facility.

– Prolonged contact of used engine oil with

the skin may cause skin damage. Always

wash oil off immediately with soap and wa-

ter to protect your skin.

Observe the safety precautions ðpage 250, Gen-

eral information.

Note

The engine oil must be changed at the intervals

specified in the Warranty & Maintenance Book-

let. This is very important because the lubrication

function of the oil gradually declines during regu-

lar vehicle operation.

Do not mix any additives with the engine oil.

Additives may cause engine damage that is

not covered by your New Vehicle Limited War-

ranty.

The engine oil should be changed more frequent-

ly under certain circumstances. Have the oil

changed more frequently if you often drive short

distances, your vehicle is predominantly in stop-

and-go traffic situations, is in very dusty environ-

ments, or is operated for long periods of time in

temperatures below zero.

For the sake of the environment

– Before changing the engine oil, make sure

you can dispose of the used engine oil cor-

rectly.

– Engine oil must always be disposed of cor-

rectly. Do not dump it in the yard, in the for-

est, or in open water, river channels, or sew-

ers.

Cleansing additives in the oil make fresh oil ap-

pear darker after the engine has run briefly. This

is normal and no reason to change the engine oil

more frequently than recommended.

– Have your used engine oil recycled by bring-

ing it to a used oil collection site or contact

a gas station.

Because correctly disposing of engine oil is diffi-

cult and special tools and technical knowledge

are needed for an oil change, Audi recommends

having your engine oil changed by an authorized

Audi dealer or authorized Audi Service Facility.

Checking and Filling

Coolant additive

Cooling system

The coolant additive is made of anti-freezing and

corrosion protection agents. Only add the follow-

ing coolant additives mixed with distilled water.

Coolant

The engine cooling system is filled with a mixture

of purified water and coolant additive at the fac-

tory. This coolant must not be not changed.

Coolant additive

G12evo

Specification

TL 774 L

The coolant level is monitored using the  indi-

cator light. However, you should occasionally

check the coolant level.

The amount of coolant additive that needs to be

mixed with water depends on the climate where

the vehicle will be operated. If the coolant addi-

tive percentage is too low, the coolant can freeze

and damage the engine.

Messages

The following messages may appear, depending

on the vehicle equipment:

Note

– If the coolant level is too low, add coolant

ðpage 259. Only continue driving once the in-

dicator light turns off.

– Before the start of winter, have an author-

ized Audi dealer or authorized Audi Service

Facility check if the coolant additive in your

vehicle matches the percentage appropriate

for the climate. This is especially important

when driving in colder climates.

 Coolant temperature: too high. Please let

engine run while vehicle is stationary

Let the engine run at idle for a few minutes to

cool off, until the indicator light turns off.

– If the G12evo coolant additive is not availa-

ble in an emergency, do not add any other

additive. You could damage the engine. If

this happens, only use distilled water and

restore the correct mixture ratio with the

specified coolant additive as soon as possi-

ble.

– If the indicator light does not turn off, do not

continue driving the vehicle. See an authorized

Audi dealer or authorized Audi Service Facility

for assistance.

 Coolant system: malfunction! Please turn

off engine

– Only refill with new coolant.

Do not continue driving, shut off the engine, and

turn off the ignition. See an authorized Audi deal-

er or authorized Audi Service Facility for assis-

tance.

– Radiator sealant must not be mixed with

the coolant.

– You can continue driving if the permitted

G12evo coolant additive was not added.

However, go to an authorized Audi dealer or

authorized Audi Service Facility immediately

to have the coolant replaced to reduce the

risk of engine damage.
