08 Cayenne base model code p12a1 and p2189 pending

[porscherescuer]

Hi everyone,

It's been a while since I've been on here...thank the Porsche Gods.  Here recently my wife's cayenne has been throwing a cel. Usually after getting gas it turns itself off. The first time this happened was back in March.  I bought a new gas cap back to see if that was the problem and the light went off and stayed off for 6 months and 10,000 miles.  Here recently it's been coming on with the p12a1 code and now it's showing a p2189 pending. Any ideas?  Could the gas cap be going out again?  Not likely I wouldn't think. Any help would be great.

Any ideas guys?

Pending codes are just that "pending".

Run the diagnostic again and see if you have any fault codes.

The p12a1 isn't pending.  Only the 2189 is pending

What did you use to pull the codes?

P12A1 is not in my 2009 Cayenne DME manual.

Hi Loren, 

Appreciate the help.  It's an 08, not sure if that matters.  I used a normal obd2 scanner, not durametric.  I'm not seeing much on this code either, mainly why I'm asking for any ideas.  Thanks

Sorry, many codes are Porsche specific so a generic scanner tells us very little.

Need to scan with Durametric or a PIWIS to get correct fault codes.
