Having problems with your 2005 Porsche Cayenne ?
I have a 2005 porsche cayenne turbo The engine idle drops while driving and car seems to stall
This may be due to a reprograming needed, contact dealer and see if there are any bulletins on this problem, also i would check the air filterbox and make sure nothing is blocking air flow, then if all looks good then i would have the computer scanned to see if any fault codes are stored due to this problem.
