Panamera GTS 970 Oil Pressure Sensor Hack
Great write ups - thanks all.
Just completed this on my 2012 Panamera GTS.
As others have said getting the sensor off is pretty straightforward but getting the new one on is an unpleasant experience.
After giving up on trying to get the sensor in place for the bolts I decided a new approach was necessary. I slid the LHS sensor and housing onto a M6 15cm bolt then got this a little into the LHS bolt hole. The extra length gives you more space to manipulate and turn the bolt. You can also see the LHS hole while you’re doing this.
Having got this long bolt in place you can slide the sensor and housing along it to the block in reasonable position to fit the RHS bolt. I found that the electrical connector was making the sensor and housing sit too high on the RHS. Using a snake camera I was able to see the correct position to get the bolt in. I then firmed up the RHS bolt a little to keep everything in place, removed the long M6 bolt and fitted the correct LHS bolt.
For info this was a right hand drive car and LHS/RHS above is when looking from front to the back. Also I let the oil settle overnight before starting and there was no leakage when the sensor was removed.
The sensor replacement cured my problem.

Hey @johanvanderwalt , do you happen to have a part # or measurements of the o-ring needed between the engine and metal piece?

After replacing the sensor mine was cured for a while, then came back.
Next I replaced the Solenoid in the oil pump with the same result, cured for a while then came back.
I now replaced the ECU and loaded new software - it also made no difference.
