Hi there, my cayenne won't drive as long i have the relay placed at 1/6 (the 404 relais) functioning. Once I take it out the car runs perfectly on one pump but once I put it back in the car stops working although I hear both fuel pumps working. What to do? Thanks for your response.
Help!!! I'm trying to replace the right passenger door regulator. Removed doorpanel, rivets, steel panel, rivets at the bottom side of the regulator, the connection between the window and the regulator (glass window taped so it won't fall down) but am unable to get the regulator out!? Somehow it seems it is fixed at the metal bar? Could somebody help me? I'm really desperate! Can't find any tutorial anywhere.... Thanks!
