Driving with an insufficient oil level is likely to
cause severe damage to the engine.
@ 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 en­
gine at regular intervals, preferably each
time you refuel, and always before going
on a long trip.
-If you have the impression your engine con­
sumes excessive amounts of oil, we recom­
mend that you consult an authorized 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. An authorized Audi dealer has instruc­
tions about how to measure oil consump­
tion accurately.
