Hey guys....trying to scan a check engine light and read the following fault codes. I can not find these codes on any forum or list of fault codes. Does anyone know what they are or seen them before? Is there a better tool for pulling codes out of the 958?
Tank system major leak - that seems a rather straight-forward code. Is the gas cap on tight? Is the gas cap still good? (Check it for cracking rubber seals..) The other two are interesting - they mean the pre-cat O2 sensors aren't responding in the amount of time the ECU expects. If there is the capability of graphing the output of them, I'd suggest doing that from a cold start. They should start reponding within about 30 seconds if the heaters are working. If the heaters on both aren't working, I'd be looking at fuses..

Ok, so cap was a bit loose in my opinion (have instructed wife on how to properly close) and for good measure I ordered a new one as the rubber seal in the cap looked a bit beat up.
More importantly....Durametric tech support was able to help me get the proper codes out of the durametric. Updating to the latest version with drivers was step one...followed by getting the fault codes from the side menu Engine module as opposed to running short test on all modules. You can see the two separate results obtained (left side running direct from module/right side by running all short test command)
The codes pulled on the left at least tie out to the descriptions. I cleared codes and will see if they come back. If the code comes back and it was not the cap...and it sounds like the problem lies in the EVAP system. Either leak detectors or vacuum pumps (quick searches on the codes only brought back older Cayenne threads)
At least yours makes it through a short test. Mine freezes every time it gets to the airbag. So yes durametric is useless for me.
Also my icarscan has stopped working and that app crashes too. Might as well buy a clone PIWIS II. Neither durametric nor launch China has customer service worth a crap.
