17Lubrication System
Edition 08.96

Testing oil pressure and oil pressure switch
Special tools, testers and aids required
Oil pressure tester (e.g. V.A.G 1342)
Diode test lamp (e.g. V.A.G 1527)
Adapter cable set (e.g. V.A.G 1594)
Current flow diagram
Operation of dynamic oil pressure warning system
Testing warning lamp After ignition on („terminal 15 on“) and engine not running, the oil pressure warning lamp flashes (not on models with Auto Check System).
Warning criteria
Engine not running and oil pressure switch closed.
Coolant temperature greater than 60 °C, engine speed greater than 1500 rpm and oil pressure switch open.
At an engine speed of more than 5000 rpm an active oil warning is not cancelled, irrespective of the position of the oil pressure switch.
If the voltage supply of the control unit is o.k. (terminal 15) and the oil pressure switch is open for longer than 0.5 seconds at engine speeds of more than 1500 rpm, this is stored. If this condition occurs three times during „terminal 15 on“, the warning becomes or remains active even at engine speeds of less than 1300 rpm.
Test conditions
Engine oil level o.k.; inspect page 17-10
Oil pressure warning lamp (K3) should come on when ignition switched on.
The o.k. readout on vehicles with Auto Check System should come on (select symbol)
Engine oil temperature at least 80 °C (radiatorfan should have cut in once)

c - Oil should be topped up. It is sufficient, after topping up, for the oil level to be within the range -b- (chequered area).
Note:
The oil level must not extend beyond the max.marking of the dipstick.
