    Interested to know what your running problem symptoms were? I got no codes ever to follow but still have a temperamental running issue of hesitation and stutter, startup, idle etc is perfect and wot is pretty good also up at high rpm but through 1k-4k its jittery kangaroo most of the time and even like it in neutral or park just revving you can feel at certain rpm's it's not happy. 

    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!

  2. 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?
