  1. Hi, this is very stressed me out, here is a long story; 1 month ago that my 04 CTT's driver side fuel pump went out, thanks this forum that i searched and pulled the fuse to force run on the passenger pump to drove couple days, it was running fine and i didnt drive hard, car was totally normal. the nightmare comes after the new fuel pumps came in, i changed both but now sometimes it gets so hard to start, have to crank for 20-30 seconds even it finally starts it will stall in 1 second that i have to press on gas to make it alive(never happen during cold start in the morning, only happens after i drove it and parked for like 10-30 minutes, drove on the freeway, if i try to pass or accelerate the fuel will cut off and engine turned off, i had to put in neutral to move the car on the shoulder and start it again to drive away which is very dangerous. i installed the old fuel pumps back and pulled the left pump fuse, same thing! which didnt happen when my old driver pump went bad. Whats the magic here? i assumed that i connected a fuel line wrong between the pumps? but the car drives fine most of the times, someone please help, thank you!
  2. 04 Cayenne Turbo, when i accelerate hard the right front is having loud knock noise, you can feel something is knocking with vibration. I went to a shop they said if is the sounds of Axle, so i got a new one and changed it, the knocking noise still exist, anyone had this same problem please give a little help. thanks!
  3. 04 Cayenne Turbo, The dash is show a car with tailgate in RED while im driving, it will keep Beep every time i take off from a stop, it is very annoying. I did make sure the glass and the tailgate are closed. anyone know this RED trunk dash message is for the glass or the tailgate? it must be a broken sensor that i want find it to adjust or unplug it or short it out in the meantime while im looking for a new trunk sensor to replace.
  4. Hi, im a new Cayenne owner, recently just bought a 04 turbo but the PCM doesnt work at all, no sound, doesnt eject the disc or anything, it will turn on but screen will show all black and once i push the power button it will just turn off ( you can tell the LCD is off not on with all black color). i did try 1 4 8 reset and took out the unit and opened and re flow with a heat gun, nothing helped, i believe i need another new unit. My question here, my car came with factory BOSE sound, which means it has MOST fiber Optic connection for the factory amp, can i just get any 04-07 PCM 2.1 and plug in it will support the Bose amp (i looked on ebay, all the back connections are same compare to mine) or i have to look for a PCM unit off a factory Bose system car? thanks for reading.
