-Contact your authorized Audi dealer for assistance if
necessary.
If the engine coolant level is correct, then the radiator fan may be
the cause of the malfunction.
If the generator warning/indicator light should also illuminate
=> page 19 , then the fan belt may be damaged.

Engine oil specifications

The engine oil used in your Audi needs the right kind of
oil.
The engine in your Audi is a sophisticated powerp lant that was built
to exacting specifications. This engine needs the right kind of
engine oil that meets specifications regarding quality and viscosity
so that it can run smoo thly and re liably. Choosing the right oil and
changing oil wi thin the time and mileage interva ls printed in your
vehic le's Maintenance
& Warranty booklet matters a lot more today
than it did years ago. Audi has developed a special quality standard
for engine oil that will help assure that your vehicle's engine will get
the lubrica tion it needs for proper operation.
Modern engine lubrication has taken a quantum leap in the last few
years. Many synthetic oils available today provide better engine
lubrication that can outlast traditional petroleum -based oils,
making them a smart choice for use throughout the life of your Audi.
Whether you use synthe tic or petro leum-based engine oil, the oil
that you use must conform to Audi's oil quality standard VW 502 00
to help keep your vehicle's engine running smoothly and help prevent the formation of harmful deposits, sometimes called
"sludge,' ' that over time can lead to expensive repairs. •

Checkin g and fillin g -

•
At the time of printing, engine oils available in the U.S . and Canada
t hat meet the exacting specifications of Audi oil standard VW 502 00
are synthetic engine oils . This does not mean, however, that every
synthetic engine oil will meet Audi oil standard VW 502 00. So
always be sure that you use an approved oil.
To help prevent the formation of harmful deposits use only oil with
the follow ing spec ifica tions pr inted on the oil container:
Au di oi l stan dar d VW 502 00
Oil container labels may carry the specification singly or in combi­
nation with other designations and o il quality standards.
V isc osit y
Engine oils are graded according to their viscosity . The proper
viscosity grade oi l for your engine depends on climactic or seasona l
conditions where you drive . You can use oil with a v iscosity grade of
SAE 5W40 across all temperature ranges for normal driving condi ­
tions.
However, if eng ine oil viscosity grade SAE 5W40 is not available, you
can a lso use viscosity grade SAE 5W-30 or SAE 0W-40 as long as it
meets Audi oil qua lity standard VW 502 00 specifications .
Because engine oil that meets the Audi oil standard may not be
available everywhere when you need it, we s trong ly recommend
that you a lways carry with you an extra quart ( liter) of oil that
expressly conforms to the VW 502 00 specification, in case you have
to top off the o il while on the road.
On ly if the level of the oil is at or below the minimum mark on the
oi l dipstick -and no oil that express ly conforms to Audi oi l standa rd
VW 502 00 specifications is available -may you top off with a high
qual ity engine oi l, preferably synthetic -based, t hat meets ACEA A3,
ACEA A5 or ACEA 85, API SL or ILSAC GF -3 specifications, but even
then, only in viscosity grades SAE 5W -40, SAE 5W -30, or SAE 0W -40.
However, dur ing the entire time between oi l change intervals, never
top off w ith more than a total of 0.5 qt/liter engine oil that does not
confo rm to Audi oil specificat ion VW 502 00. For more information about engine oil that has been approved for
your vehicle, p lease con tac t ei the r your authorized Audi dea ler or
Aud i Customer Relations at 1 (800) 822-2834 or visit our web site at
www .audiusa .com or www .audicanada.ca. Here you will a lso find a
current list of oils (manufacturers, brand names etc.l that conform
to Audi oi l standard VW 502 00 .
Changing the engine oil
The engine oil and oil filter must be changed according to the
mi leage (k ilometers) and time intervals specified in your vehic le's
Maintenance
& Warranty booklet. Do not exceed these intervals -
harmfu l deposits from old engine oil can reduce engine perfor­
mance and can lead to expens ive eng ine repairs.
Changing the oil at the recommended interva ls is so very important
because the lub ricating properties of oi l decrease gradua lly during
normal vehicle use. If you are not sure when you have your oil
changed, ask you r authorized Audi Service Advisor .
Under some circumstances the engine oil should even be changed
more frequently. Change oi l mo re often if you drive mostly short
distances, operate the vehicle in dusty areas o r mostly under stop­
and -go traffic conditions, or when you use your vehicle where
temperatures stay below freezing point for long per iods.
Detergent additives in the oil will make fresh oi l look dark after the
engine has been running for a sho rt time. Th is is normal and is not
a reason to change the oil more often than recommended.
D amag e or malfun ctions due to la ck of mai nten ance
It is essential that you change your oi l at the recommended interva ls
using on ly engine oil that complies with Audi oil standard
VW 502 00. Your Limited New Vehicle War ranty does not cover
damage or malfunctions due to failure to fol low recommended
maintenance and use requirements as set forth in the Audi Owner's
Manual and Maintenance
& Warranty booklet . Your dealer wi ll have
to deny warranty coverage unless you present to the dealer proof in
the form of Service or Repair Orders that all scheduled maintenance
was performed in a timely manner. •

Engine oil consumption
The engine in your vehicle de pen ds on an ade quate
amount of oil to lubric ate and co ol all of its moving parts.
In order to provide effective lubrication and cooling of interna l
engine components, al l internal co mbustion engines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change sign ificant ly over the life of the engine . Typ ical ly,
engines with a specified break -in period (see=>
page 192) consume
more oil duri ng the brea k-in period than they consume afte r oil
consumption has stabi liz ed.
Unde r no rmal conditions, the rate of oil consumption depends on
the quality and viscosity of t he oil, the RPM ( revo lutions per m inute)
at which the engine is operated, the ambient temperature and road
co nd itions. Further factors are the amount of oi l dilut io n from water
condensation or fue l residue and the oxidation leve l of the oil. As
any e ng ine is subject to wear as mil eage builds up, the o il consump ­
tion may increase over time until replacement of worn components
may become necessary .
With all these var iables com ing into p lay, no standard rate of oil
consu mption can be es tab lished or speci fied. There is no a lternative
t o regular and frequent checking of the oi l leve l, see Note.
If the yellow engine oi l level warning symbol in the instrumen t
cluster _ lights up, y ou should check the oil level as soon as
possible
with the oil dipstick=> page 224. Top off the oil at your
ea rlies t conve nience =>
page 225.
ln. WARNING
Before you check anything in the engine compartment , alway s
re ad and heed all WARNINGS =>
& in "Working in the engine
c ompartment" on
page 220.
0 Note
D riving with an insufficient o il level is lik ely to cause seve re damage
to the engine .
[ i ] Tips
• The oil pressure warning display 't!:r. is not an indicator of the oil
level. Do not rely on it. Instead , check the oil level in your engine at
regular intervals , preferab ly ea ch time you refuel , and alw ays before
going on a long trip.
• I f you have the impression your engine consumes excessive
a m oun ts o f oi l, we recommend tha t you consu lt your Audi dealer to
have the cause of your concern properly diagnosed . Keep in mind
that the acc urate measure ment o f oil co nsum ptio n requires grea t
care and may take some time . Your Audi dea ler has instructions
about how to measu re oil consump tion accurately. •
