Engine oil
Engine oil specifications
The engine oil used must conform to exact speci­
fications.
The service interval display in the instrumen t
cluster of your vehicle will inform you when it is
time for an oi l change. We recommend that you
have your oi l changed by an authorized Audi Serv­
ice Advisor.
If you have to top off the oil between oil changes,
use the Audi oil quality standard specified in the
table .

engine vw 504 00
Diesel vw 507 00
engine

Using the proper engine oil is important for the
functionality and service life of the engine. Your
engine was factory-filled with a high -quality oil
which can usually be used throughout the entire
yea r.
Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions d ue to failure
to follow rec ommended maintenance and use
requireme nts as s et forth in the Audi Owner's
Manual and Warranty & Maintenance booklet.
- Use only a high quality engine oi l that ex-
pressly complies with the Au di oil quality
standard specified for your vehicle's engine.
Using any o ther oil can cause serious engine
damage.
- Do not mix any lubricants o r other additives
into the engine oil. Doing so can cause en­
gine damage.
@ Tips
If you need to add oil and there is none availa­
ble that meets the Audi o il quality standard
your eng ine requ ires, you may add a total of
no more than 0 .5 quart/li ter of a h igh-quality
"synthet ic"oil that meets the following speci ­
fications.
- Vehicles with gasoline eng ine: ACEA A3 o r
API SM with a viscosity grade of SAE OW-30,
SAE SW-30 or SAE SW-40.
- Vehicles with diesel eng ine: ACEA C3 or
API CF with a viscosity grade of SAE OW-30
or SAE SW -30.
- For more information about engine oil that
has been approved for your vehicle, please

Engine oil consumption
The engine in your vehicle depends on an ode-
;::: quote amount of oil to lubricate and cool all of
~ its moving parts . co ,....,
~ In order to provide effective lubr ication and cool-,....,
:=: ing of internal engine components, all internal
Ch eck ing and Filling
combustion engines consume a certain amo unt
of oil. Oil consumption varies from engine to en­
gine and may change s ignificantly over the life of
the engine. Typ ically, engines w ith a specified
break-in period (see¢
page 77) consume more
o il during the break-in per iod than they consume
after o il consumption has stab il ized.
Under normal cond itions, the rate of oil con ­
sumption depends on the quality and viscos ity of
the oil, the RPM (revolutions per minute) at
wh ich the engine is operated, the amb ient tem­
perature and road co ndit ions. Further facto rs a re
the amount of oi l di lution from wate r condensa­
tion or fuel resid ue and the oxidat ion level of the
o il. As any engine is subject to wear as mileage
builds up, the oil consumption may increase over
time unti l replacement of worn components may
become necessary.
With a ll these variab les coming into play, no
standard rate of oil consumption can be estab ­
li shed or specified. There is no alternative to reg­
u lar and frequent checking of the oi l level, see
Note .
If the yellow engine oil leve l warning symbo l l!I
in the instrument cluster lights up, you should
check the oi l level as soon as possible
¢
page 242. Top off the o il at your earliest con­
venience ¢
page 242.
A WARNING
-Before you check anyt hing in the engine com-
partment, always read and heed all WARN­
INGS
¢page 236.
(D Note
Driving wit h an insufficient oil level is likely to
cause severe damage to the eng ine.
(D Tips
- The oil pressu re wa rning display. is not
an indicator of the oi l le vel. Do not rely on
i t. In stead , check th e oil level in your en­
gine at regular intervals, preferably each
time you refuel, and alway s before goi ng
on a long trip .
241

Checking and Filling
-If you have the impression your engine con ­
sumes excessive amounts of oil, we recom­
mend that you consult an authorized Aud i
dealer to have the cause of your concern
properly diagnosed. Keep in mind that the
accurate measurement of oil consumpt ion
requires great care and may take some
time. An authorized Audi dealer has instruc­
tions about how to measure oil consump­
tion acc urately.
Checking the engine oil level
Fig . 19 5 Gasol ine eng ine oil dipstick: guide for measuring
the oil level (example)

Read and follow the W ARN INGS before check­
i n g anyth ing in the eng ine compartmen t
¢ page 236, Working in the engine compart­
ment.
Determining the oil level
• Park your vehicle on a level surface .
• Let the engine run in id le br iefly whi le it is at
operating temperature and the n shut the e n­
gine off .
• Wai t approx imately two m inutes .
242
• Remove the oil dipstick. Wipe off the oil dip­
stick with a clean cloth and insert it all the way
in aga in .
• Remove the dipstick again and then read the o il
level
¢ fig. 195 or ¢fig. 196.
• Evaluate the oil level¢ table on page 242. Add
eng ine oi l if necessary ¢
page 242.
~ You must add oi l. After adding oil, the level
shou ld be in the

@ Do not add any oil. You may con tinue driv-
ing .
0 Do not add any oil. Drive to an authorized
Audi dealer or authorized Audi Service Fa-
cility immediately.
Applies to vehicles with a d iesel eng ine: fuel can
get into the engine o il if you run your vehicle with
biodiesel. This raises the o il level in the eng ine. It
also decreases the quality of the engine oil
¢page 24.
The oil consumption o f the engine may be up to
1/2 qua rt per 600 miles (0.5 l ite r per 1,000 km),
depending on d riving style and cond itions. Con­
sumption may be highe r during the firs t
3,000 miles (5,000 km) . Bec ause of this, the en­
gine o il level must be checked regularly.
It would
be best to check each time you refuel your veh icle
and before long drives .

Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta ­
tion .
Before you check anything in the engine compart­
ment,
always read and heed all WARNINGS
c::> page 236.
The engine o il must be changed according to the
intervals specified in your Warranty
& Mainte­
nance book let. This is very important because the
lubricating properties of oil diminish gradua lly
during norma l vehicle use.
Under some circumstances the engine oil shou ld
be changed more frequent ly. Change oil more of­
ten if you drive mostly short distances, operate
the vehicle in dusty areas or under predominantly
stop-and-go traff ic conditions, or have your vehi­
cle where temperatures remain below freezing
for extended periods.
Detergent additives in the oi l 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 o il changed by an authorized
Audi dealer or
a qualified service stat ion.
If you choose to change your oil yourself, please
note the following important information:
A WARNING ,-~
To reduce the risk of personal injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protection.
243

Checking and Filling
-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 .
CD 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 you can properly dispose of
the used oil.
- Always dispose of used engine oil properly.
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 service station.
Cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro­ tects the engine from freezing in the winter.
The cooling system is sealed and generally re­
quires little attention.
The cooling system has been filled at the factory
with a permanent coolant which does not need to
be changed. The coolant consists of a mixture of
244
specially conditioned water and the manufactur­
er's glycol-based coolant additive Gl3 antifreeze
with anticorrosion additives (50% for USA mod­ els; 60% for Canadian models). This mixture
both assures the necessary frost protection and
protects metal components in the engine's cool­
ing system from corrosion and scaling. It also
raises the boiling point of the coolant.
Do not reduce the concentration of the coolant in
the summer by adding plain water.
The propor­
tion of coolant additive must be at least 50%
but not more than 60%
to maintain antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant could
freeze and damage the vehicle heating and en­
gine cooling system.
For year-round driving, antifreeze is added at the
factory for temperatures down to:
--31°F(-35°C)USA
- - 40 °F ( - 40 °C) Canada.
If you must add coolant, use a mixture of water
and coolant additive. Mixing the coolant additive
with distilled water is recommended.
A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN­
INGS
~ page 236.
CD Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in your
vehicle is sufficient to meet the climate con­ ditions. This is especially important if you
live in a region where the winter is extreme­
ly cold.
If necessary, increase the proportion
of coolant additive to 60%.
- When adding coolant additive to your cool­
ing system, remember:
- We recommend using only coolant addi­
tive Gl2++ or G13 (check the label) for
your vehicle. This coolant additive is avail­
able at authorized Audi dealers. Other
types of antifreeze can significantly re­
duce corrosion protection. The resulting

.... N

.... I.Cl ....
corrosion can cause a loss of coolant and
serious engine damage .
- Do not add any type of radiator leak sealant
to your vehicle's engine coolant . Adding ra­
diator repair fluid may adversely affect the
function and performance of your cooling
system and could result in damage not cov­
ered by your New Vehicle Limited Warranty.

ment.
Checking the engine coolant level
• Park your vehicle on a level surface .
• Switch the ignition off .
• Read the coolant level on the coolant expansion
tank
¢ fig. 198 . The coolant level must be be­
tween the markings when the engine in cold .
When the engine is warm it can be slightly above the upper marking.
Adding coolant
Plug-in hybrid drive*: your vehicle has two cool­
ant expansion tanks that are separate from each
other. The smaller of the two expansion tanks
must not be opened
¢ page 108. Read and fol­
low the important safety precautions ¢
A in
Coolant on page 109.
Requirement: there must be a residual amount of
coolant in the expansion tank ¢(D .
• Let the engine cool down .
Checking and Filling
• Place a cloth over the coolant expansion tank
cap and unscrew the cap counterclockwise
¢ A .
• Add coolant mixed in the correct ratio
¢
page 244 up to the upper marking.
• Make sure that the fluid level remains stable.
Add more coolant if necessary.
• Close the cap securely .
A coolant loss suggests a leak. Immediately drive
your vehicle to an authorized Audi dealer or au ­
thorized Audi Service Facility and have the cool­
i ng system inspected. If the cooling system is not
leak ing, a loss can come from the coolant boiling
through overheat ing 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
with the engine hot. There is a 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
coo lant 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.
The ethylene glycol in engine coo lant can
catch fire under certain circumstances .
- The coolant additive and the coolant can be
dangerous to your health . For th is reason,
keep the coolant in the original container
away from children. There is a risk of poi­
soning .
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, wh ich
increases the risk of persona l injury.
(J) Note
Do not add coolant if the expansion tank is
empty . Air could enter the cooling system and
damage the eng ine.
