226 Checking and filling
@ Tips
-The oil pres sure 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 t ime you refuel, and always
before going on a long trip.
- If you have the impression your engine
consumes excessive amounts of oil, we
r ecommend 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 requires great care and may
take some time. Your Audi dealer has in ­
str uctions about how to measure oil con­
sumption accurately.
