2008 Cayenne startup
I have a 2008 Cayenne Base V6, purchased with major problems that have all been repaired, so I thought. Vehicle had fuel problems from the start. Replaced, both tank pumps, Engine high pressure pump, fuel pressure sensor, and after all this the vehicle runs great! , other than every morning when going to start it, it starts right up just fine, then dies quickly, like it ran out of fuel. I do that like 4 to 5 times or so, and after that it runs perfect, all day. Until the next morning and the same thing happens, every morning. And it gives out no codes to search for the fix, its really making me look dumb, what am I missing?

My 2006 Cayenne S had a similar problem, especially after fuel up. I changed out the Fuel Evap. Canister Purge Valve breather line and my problems went away. On my 4.5L engine it was located on the right side of the engine (Facing front of engine) going from the front to the rear.
