Chec k ing and filling
Detergent additives in the oil will make fresh
oil look dark after the engine has been run-
ning for a short time . This is norma l and is not
a reason to change the oil more often than
recommended.
Damag e or malfun ction s due to lack of
mainten ance
It is essent ial that you change your oil at the
recommended intervals 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 failure to follow recommended mainte-
nance and use requirements as set forth in
the Audi Owner's Manual and Warranty
&
Maintenance book let . Your dealer will have to
deny warranty coverage un less you present to
the dealer proof in the form of Service or Re-
pair Orders that all scheduled maintenance
was performed in a timely manner.
Engine oil consumption
The engine in your vehicle depends on an ade-
quate amount of oil to lubricate and cool all
of its moving ports.
I n order to prov ide effective lubr ication and
cooling of internal engine components, all in-
ternal comb ustion engines consume a certain
amount of oil. Oil consumption varies from
engine to engine and may change significantly
over the life of the eng ine. Typically, engines
with a specif ied break-in per iod (see
c::;,
page 162)
consume more oil during the
break-in per iod than they consume after oil
consumption has stabilized.
Under normal conditions, the rate of oil con-
sumpt ion depends on the quality and viscosity
of the oil, the RPM (revolutions per m inute) at
which the engine is operated, the ambient
temperature and road condit ions. Furthe r fac-
tors are the amo unt of oil dil ution from wate r
condensation or fuel residue and the oxida-
tion level of the oi l. As any engine is subject to
wear as mileage bui lds up, the oil consump-
tion may increase over t ime until replacement
of worn components may become necessary.
Wi t h all these variab les coming into play, no
standard rate of oil consumption can be es-
tab li shed or specified. There is no alte rnative
to regular and frequent checking of the oil lev-
el, see
Note .
If
the yellow engine oil level warning symbo l

sho uld check the oil level as soon as possib le

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 refue l, and always
before going on a long trip.
- If you have the impressio n your engine
consumes excessive amoun ts 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 con-
sumption requ ires great care and may
take some t ime . Your Audi dealer has in-
struct ions about how to measure oil con-
sumption accurately.
