Audi recommends Longlife high performance
engine oil from Audi Genuine Parts
Using the proper engine oil is important for the
functionality and s ervice life of the engine. Your
engine was factory-filled with a high -quality oil
which can usually be used throughout the entire
year .
(D Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's
Manual and Warranty
& Maintenance booklet .
-Use only a high quality engine oil that ex-
pressly complies with the Audi oil quality
standard specified for your vehicle's engine .
Using any other oil can cause serious engine
damage.
-Do not mix any lubricants or other additives
into the engine oil. Doing so can cause en­
gine damage.
(D Tips
If you need to add oil and there is none availa­
ble that meets the Audi oil quality standard
your engine requires, you may add a total of
no more than 0.5 qt (0.5 l) of a high-quality
"synthetic"oil that meets the following speci­
fications.
-ACEA A3 or API SM with a viscosity grade of
SAE 0W-30, SAE 5W-30 or SAE 5W-40.

· Engine oil consumption
T he engine in your vehicle depends on on ade­
quate amount of oil to lubricate and cool oil of
its moving ports .
In order to provide effective lubrication and cool­
ing of internal engine components, all internal
combustion engines consume a certain amount
of oil. Oil consumption varies from engine to en­ gine and may change significantly over the life of
the engine . Typically, engines with a specified
break-in period
(see ¢ page 74) consume more
oil during the break-in period than they consume
after oil consumption has stabilized.
Under normal conditions, the rate of oil con­
sumption depends on the quality and viscosity of
the oil , the RPM (revolutions per minute) at
which the engine is operated, the ambient tem­ perature and road conditions. Further factors are
the amount of oil dilution from water condensa­
tion or fuel residue and the oxidation level of the
oil. As any engine is subject to wear as mileage
builds up, the oil consumption may increase over
ti me until replacement of worn components may
become necessary.
With all these variables coming into play, no standard rate of oil consumption can be estab­
lished or specified . There is no alternative to reg­
ular and frequent checking of the oil level , see
Note.
If the yellow engine oil level warning symbol II
in the instrument cluster lights up, you should
check the oil level as soon as possible
¢ page 321. Top off the oil at your earliest con­
venience
¢ page 321.
A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN­
INGS
¢ page 316.
(D Note
Driving with an insufficient oil level is likely to
cause severe damage to the engine.

@ Tips
- The oil pre ssure w arning display. i s not
an indicator of the oil level. Do not rel y on
it. Instead , check the oil level in your en­
gine at regular inte rval s, preferably each
t ime you refuel , and alway s befo re going
on a long trip.
- If you have the impression your engine con­
sumes excessive amounts of oil, we recom­
mend that you cons ult an autho rized Aud i
dealer to have the cause of your concern
properly d iagnosed . Keep in mind that the
accurate measurement of oil consump tion
requi res great care and may take some
time. An a uthorized Audi dea ler has instruc ­
tions about how to measure oil consump ­
tion accurately .

Checking and Filling
CJ) Note
-The engine oil level must not be under the
marking
(D r=> fig. 272, because this increas­
es the risk of engine damage.
- After adding engine oil, the oil level must
not be above the marking
@ c:> fig . 2 72, be­
cause this increases the risk of catalytic con­
verter and/or engine damage. Do not start
the engine. Contact an authorized Audi
dealer or authorized Audi Service Facility to
have excess engine oil extracted if necessa­
ry .
- Do not mix any additional lubricants into
the engine oil. Damage caused by such addi­
tives is not covered by the warranty .
@ For the sake of the environment
-Engine oil should never enter the sewer sys­
tem or come into contact with the ground under any circumstances.
- Pay attention to legal requirements when
disposing of empty oil containers.
@ Tips
The engine oil consumption may be up to
0 .S 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 would be
best to check each time you refuel your vehi­
cle and before long drives.
Changing the engine oil
We recommend that hove your oil changed by on
authorized Audi d eal er or o qualified s ervice sta­
tion.
Before you check anything in the engine compart­
m ent,
always read and heed all WARNINGS
r=> page 316.
The engine oil must be changed according to the
intervals specified in your Warranty
& Mainte­
nance bookl et. This is very important b ecause the
lubric ating properties of oil diminish gradually
during normal vehicle use.
322
Under some circumstances the engine oil should
be changed more frequently. Chang e oil more of­
ten if you drive mostly short distances, operate
the vehicle in dusty areas or under predominantly
stop-and-go traffic conditions, or have your vehi­
cle where temperatures remain below freezing
for extended periods .
Detergent additives in the oil will make fresh oil
look dark after the engine has been running for a
short time . This is normal and is not a reason to
change the oil more often than recommended.
Because of the problem of proper disposal, along
with the special tools and necessary expertise re­
quired, we strongly recommend that you have
your oil changed by an authorized
Audi dealer or
a qualified service station .
If you choose to change your oil yourself, please
note the following important information :
,&. WARNING
To reduce the risk of personal injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protection.
- To reduce the risk of burns from hot engine
oil , let the engine cool down to the touch.
- When removing the oil drain plug with your
fingers, stay as far away as possible . Always
keep your forearm parallel to the ground to
help prevent hot oil from running down your
arm.
- Drain the oil into a container designed for
this purpose, one large enough to hold at
least the total amount of oil in your engine.
- Engine oil is poisonous . Keep it well out of
the reach of children.
- Continuous contact with used engine oil is
harmful to your skin . Always protect your
skin by washing oil off thoroughly with soap
and water .
0 Note
Never mix oil additives with your engine oil.
These additives can damage your engine and
adversely affect your Audi Limited New Vehi­
cle Warranty .

@ For the sake of the environment
-Before changing your oil, first make sure
you know where yo u can properly dispose of
the used oil.
- Always dispose of used engine oil prope rly .
Do not dump it on garden soil, wooded
areas, into open streams or down sewage
drains.
- Recycle used engine oil by taking it to a used engine oil collection facility in your area, or
contact a serv ice stat ion.
Cooling system
Coolant
The engine coo ling system is filled with a mixture
of purified water and coolant additive at the fac­
tory. This coo lant must not be not changed.
The coolant leve l is monitored through
the . in­

mend occasionally checking the coo lant level
manually.
I f you m ust add coolant, use a m ixture of water
and coolant addit ive. Mixing the coolant additive
with distilled water is recommended.
Coolant additive
The coolant addi tive is made of anti-freezing and
cor ros ion pro tection agents. Only use the follow­
ing coolant additives . These additives may be
mixed with each other.
Coolant additive Specification

Requirement: there must be a residual amount of
coolant in the expansion tank
¢ (D .
~ Let the engine cool down.
~ Place a cloth over the coolant expansion tank
cap and unscrew the cap counterclockwise
¢_&. .
~ Add coolant mixed in the correct ratio
¢page 323 up to the upper marking.
~ Make sure that the fluid level remains stable.
Add more coolant if necessary.
~ Close the cap securely.
Coolant loss usually indicates there is a leak . Im­
mediately drive your vehicle to an authorized
Audi dealer or authorized Audi Service Facility
and have the cooling system inspected.
If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheating
and being pushed out of the cooling system.
.,&. WARNING
The cooling system is pressurized and can be­
come very hot. To reduce the risk of burns
from hot coolant:
- Do not open the coolant expansion tank cap
when the engine is hot. This increases the
risk of burns.
- Stop the engine and allow it to cool.
- Protect your face, hands and arms from es-
caping coolant and steam by covering the
coolant tank cap with a large, thick cloth.
- Turn the coolant tank cap counterclockwise
slowly and keep light pressure on the cap.
- To reduce the risk of burns, do not allow any
antifreeze or coolant to drip onto the ex­
haust system or hot engine components.
324
The ethylene glycol in engine coolant can
catch fire under certain circumstances.
- The coolant additive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the original container
and away from children . There is a risk of
poisoning.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
(D Note
Do not add coolant if the expansion tank is
empty . Air could enter the cooling system and
