Hi, this is my second post here. My name is Andy and I own a 2004 Cayenne Turbo. I'm a big fan of P cars as I'm sure we all are. My Cayenne has been great over the last year of ownership, this thing is a beast!! It's good for business and family, but recently I had trouble starting after fueling up. The engine was turned off and key removed from ignition as it always is during fill ups. When I tried to start it, it just cranked. After a few tries it finally started and was idling rough. This only happens after I fill up with gas (second time this week). I have a Vag Com cable from my previous Audis and came up with three engine fault codes p0441, p2187, and p2189. I found the explanations of each code on this site, but need to know how to go about fixing these. I'm mechanically inclined and unfortunately only have an aftermarket warranty that never covers any needed repairs. Thank you in advance for any help!

Regards,

Andy

I had same codes and symptom. Turned out to be purge valve faulty. If your gas cap is good and no obvious leaks I'd look at the fuel tank ventilation system. Good luck.

Thank you, I tried the gas cap and that wasn't it. When I called the dealer for a purge valve they said that it didn't have a purge valve and was more or less a metal piece of tubing that needed to get soldered into place to replace a faulty plastic piece. I'm also debating wheather I should do the 02 sensors??

This really sounds like a problem with the fuel tank ventilation. I'd check this before replacing o2 sensors. My indy apparently replaced the "purge valve" and I suspect there was something easily fixable as the labor charge was merely exorbitant.

Thank you for your replies.

Took it to the dealer and it turned out to be the fuel ventilation line $370 and change (not covered by Continental warranty) and also the coils were bad and causing it to idle rough, as well as a bad motor mount (these items were covered by Continental warranty). Finally, it's starting to pay off...

Andy,

I'm having the same issue. At fill up, I have to hold that gas down to get it restarted to build up pressure. I know it's the evap system but there are so many parts to check into. Do you have the part number of the part the dealer changed for you?

Thanks,

Craig
