Preliminary work
WARNING: This page is about a different car, the 2016 Porsche Macan and 2015 Porsche Macan. However, it is still accessible from the selected car via links, so may be relevant.
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 the 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 .
Information
- The oil pressure can be displayed and checked for any engine speeds using the PIWIS Tester.
- The pressure readings can be shown graphically in the data logger.
- If an oil-pressure gauge needs to be connected for further tests, proceed according to the instructions starting from "Preliminary work".
- For details of measured values, see below.
