- Engine oil pressure
If this light comes on, it indicates that the
engine oil pressure is too low.
Pull off the road and stop the engine
immediately, let it cool down and
check the engine oil level and add oil,
if necessary.
If engine oil level is normal, but the
light comes on again, do not continue
to operate the vehicle. This could
damage the engine.
Turn the engine off and contact the
nearest Audi dealer for assistance.
The oil pressure warning light is not
an indicator for low engine oil level.
To check the oil level, always use
dipstick (see page 105).
