Want to decipher error codes before clearing

Recommended Posts

I bought a Durametric and it's showing a couple of faults on my 2011 Cayenne S. Searching hasn't uncovered anything so I thought I'd post here to see if I can get clarification on what these might be prior to just clearing them and seeing if they come back.


CAN Gateway

1538 / 602

1539 / 603


I'm guessing the above could be due to having removed the PCM for repair and driving the vehicle but not really sure.



3277300 / 3201f4


Still working through a couple of issues with Durametric as it hangs when processing the airbag. They've been helpful and fully expect things to be resolved after providing quite a bit of feedback.


I also had a P0456 but replacing the fuel cap, which no longer clicked when putting it back on, took care of that.

Hi Tom


I was wondering if you had found what these fault codes meant and if how you fixed the issue.


I have a 2011 Cayenne V6, just purchased a Durametric and have the same fault codes.  I couldn't find anything on the internet on these codes.
