Preliminary Work

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2016 Porsche Panamera, 2015 Porsche Panamera, 2014 Porsche Panamera, 2013 Porsche Panamera, and 2012 Porsche Panamera. 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 tomes "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.

The adapter can be fitted without removing the Y-shaped pipe on naturally aspirated engines.
On turbo engines, remove Y-shaped pipe at the right and air box for air cleaner ahead of the throttle valve to create unrestricted access to the oil pressure sensor.
