Testing warning light
After the ignition is switched on (engine not
running), the oil pressure warning light in the
dash panel insert should come on for about 3 s
and then go out. The check is completed once
the engine is running.
Warning criteria
The visual oil pressure warning (oil pressure
warning light flashes) is activated and the buzzer
for the audible warning sounds 3 times if one of
the following conditions exists:
l „Ignition on", engine not running, oil pressure
switch closed
l Engine speed greater than 1500 rpm, oil
pressure switch opened
- If engine speed is greater than 5000 rpm,
the oil pressure warning is not cancelled;
also not if the oil pressure switch is
closed. Oil pressure warning cancelled
once engine speed less than 5000 rpm.
- If the oil pressure switch is open only
0.5...3 s at an engine speed of more than
1500 rpm, this is stored in the combi-
nation processor of the dash panel insert.
If this state occurs 3 times when the
engine is running, the oil pressure war-
ning is immediately activated and also not
cancelled at engine speed of less than
1500 rpm.
Oil pressure warning is cancelled once
oil pressure switch is closed for more than
5 s at engine speed of more than 1500
rpm or in the case of „Ignition off".
