Damage or malfun ctions due to lack of
maintenance
It
is essential that you change your oil at the
recommended int ervals using only engine oil
that complies with Audi oi l standard
VW 502 00. Your Limited New Vehicle War-
ranty does not cover damage or malfunctions
due to fail ure to fo ll ow recommended mainte-
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
Maintenance book let . Your dealer will have to
deny warranty coverage unless you present to
the dealer proof in the form of Service or Re-
pair Orders that all scheduled ma intenance
was performed in a timely manner.
Eng ine oil consumption
The engine in your vehicle depends on an ade-
quate amount of oil to lubricate and cool all
of its moving parts.
In order to provide effective lubrication and
cool ing of internal engine components, all in-
ternal combustion eng ines 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 specif ied break-in period (see
¢
page 195)
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
temperature and road condit ions. Further fac-
tors are the amount of oil dil ution from water
condensat ion or fuel residue and the oxida-
tion level of the oil. As any engine is subject to
wear as mi leage builds up, the oil consump-
tion may increase over time until replacement
of worn components may become necessary.
With all these variab les coming into play, no
standard rate of oil consumption can be es-
tablished or specified. There is no alternative
to regu lar and frequent checking of the oil lev-
el, see
Note .

Tips
- The oil pressure warning display.
is
not an indicator of the oil level. Do not
rely on it. Instead, check the oil level in
your engine at regular intervals, pref-
erably 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 an author-
ized Audi dealer to have the cause of
your concern properly diagnosed. Keep in
m ind that the accurate measurement of
oil consumption requires great care and
may take some time. An authorized Audi
dealer has instructions about how to
measure oil consumption accurately.
