Help - 06 Cayenne Base Durametric Fault Codes

Recommended Posts


I just got my Durametric kit and I am not too familiar (working on it :-D) with the fault codes. I did some digging and I believe fault code 459:PCM2 is due to the after market Kenwood navigation system installed. The steering wheel buttons of course do not work with the after market navigation system.

However, if someone could please let me know on the remaining fault codes that would be much appreciated. I was considering just clearing everything and checking the codes again after a day or two.

You need to clear all codes and then see what comes back. The power supply faults are usually due to a battery change and that same battery change can cause other erroneous faults.


Emissions fault codes are found in the Porsche OBD 2 manual for your model. The other systems fault codes are in the service manual for your model.
