Engine oil consumption
The engine in your vehicle depends on an adequate
amount of oil to lubricate and cool all of its moving parts.
In order to provide effective lubrication and cooling of internal
engine components , all internal combustion engines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change significantly over the life of the engine. Typically,
engines with a specified break -in period (see~
page 219) consume
more oil during the break-in period than they consume after oil
consumption has stabilized.
Under normal conditions, the rate of oil consumption depends on
the quality and viscosity of the oil, the RPM (revolutions per minute)
at which the engine is operated, the ambient temperature and road
conditions. Further factors are the amount of oil dilution from water
condensation or fuel residue and the oxidation level of the oil. As
any engine is subject to wear as mileage builds up , the oil consump­
tion may increase over time until replacement of worn components
may become necessary .
With all these variables coming into play, no standard rate of oil
consumption can be established or specified. There is no alternative
to regular and frequent checking of the oil level, see
Note.
If the yellow engine oil level warning symbol in the instrument
cluster lights up, you should check the oil level as soon as
possible
with the oil dipstick~ page 254. Top off the oil at your
earliest convenience~
page 255.
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS
~ & in "Working in the engine
compartment" on
page 250.
0 Note
Driving with an insufficient oil level is likely to cause severe 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, preferably each time you refuel, and always before
going on a long trip.
• If you have the impression your engine consumes excessive
amounts of oil, we recommend that you consult your Audi dealer to
have the cause of your concern properly diagnosed . Keep in mind
that the accurate measurement of oil consumption requires great
care and may take some time . Your Audi dealer has instructions
about how to measure oil consumption accurately. •

M ainte nanc e book le t.
Und er diff icult op era ting co nd iti ons, for example at extreme ly low
outsi de temperatures, in very dusty regions, when towing a trailer
very frequent ly, etc ., some service work shou ld be performed
between the intervals specified. This applies particu lar ly to:
• oil changes, and
• cleaning or replacing the air filter.
<£> For the sake of the environment
By regularly maintaining your vehicle, you help make sure that emis­
sion s tandards are maintained, thus minimizing adverse effects on
the environment. •
Important considerations for you and your
vehicle
The increasing use of electronics, sophisticated fue l injection and
emission control systems, and the generally increasing techn ical
complexity of today's automobiles, have steadily reduced the scope
of maintenance and repairs which can be carried out by veh ic le
owners.
Also , safety and env ir o nment al concerns place very strict
limits on the nature of repairs and adjustmen ts to engine and trans ­
mission parts which an owner can perform.
Maintenance, adjustments and repairs usua lly require special tools,
test ing devices and other equipment availab le to spec ial ly trained
workshop personne l in order to assure proper performance, reli ­
abil ity and sa fety of the vehicle and its many systems.
I mproper maintenance, adjustments and repairs can impair the
operation and reliability of your vehicle and even void your vehicle
warranty. Therefore, proof of servicing in accordance with the main­
te nance schedule may be a condit ion fo r upholding a possible
warranty claim made within the warranty period.
Controls . and equip­
ment . Safety first Vehicle operation
Above all, operational safety can be adverse
ly affected, creating
unnecessa ry risks for you and your passengers .
If in doubt about any servicing, have it done by your authorized Audi
dealer or any other properly equipped and qua lified workshop. We
strongly urge you to g ive your authorized Audi dea ler the opportu ­
nity to perform al l scheduled maintenance and necessary repairs.
Your dealer has the fac ilities, original parts and trained spec ia lists
to keep your vehicle running properly.

The following pages describe a limited number of procedures which

cable text and carefu lly fo llow the instruct ions given. Always rigor ­
