Sorry for the 2 year delay getting back to you! My issues turned out to be multiple, but the main culprit was a combination of issues in the fuel tank and fuel pumps. They had to remove the fuel tank and clean out tons of crap and contaminants, including rust, from it. Once they did that and replaced the fuel pumps, the Cayenne behaved like a new vehicle!
I know it’s 4 years later, but anyway... my 2007 997.1 TT sockets are different than what you described: 1. Pax side under dash is only on with ignition on. 2. Lighter is always on 3. Armrest is always on
I should have been a bit more specific about the fueling. I had no choice during a recent 500-mile return trip but to fuel with the vehicle running due to battery issues. I understand the risks, but had no choice at the time.
Thanks very much for the great tips! I'll go over everything in the morning and see what I can figure out. Cheers! David
Hi Guys, New here, and found this posting similar to the problem that cropped up on my 2005 Cayenne TT today. Very rough through all RPMs. I almost thought the Cardem bearing had busted again because of the roughness. OBD2 says Cylinder 7 misfire. I have had recent engine light issues with fuel system that only comes on when it sits idling too long, or if I left the engine running while refilling the gas. Bought a new fuel cap and helped just a bit, but still get fuel system error occasionally. Could this be related, even if only number 7 is misfiring? Perhaps 7 is at the end of the fuel journey and gets lower pressure when either the regulator or fuel pump go south? i hate to think of the expense to guess my way through this, and am hoping someone out there gets a twinge of deja vu! Any ideas?
