Information

If vehicles have fault entries relating to oil pressure, oil pump activation, oil pressure monitoring, etc. in the DME control unit (and a warning light comes "on" on the instrument cluster), proceed as follows:

Check the oil level .
Delete related faults .
Do not replace components, such as the oil pump, oil pressure sensor or oil pressure control valve if you suspect that they are faulty .

If the vehicle has not been driven for a long time (months), the control mechanism in the oil pump can become stiff ("stick").

Very short trips and a lot of loading/maneuvering can cause t↓he oil to become very diluted => Oil pressure very low. For example, 20 cold starts in quick succession can reduce the viscosity of the engine oil by 30%.

Change the engine oil. Test-drive the vehicle .
If error messages/warnings are displayed again, proceed in accordance with the instructions under Guided Fault Finding in the PIWIS Tester .

Remove engine guard. → REMOVING ENGINE GUARD
