  1. I should check the AMP in the rear (right side of the luggage). My experience says that the hose for rear window washer is broke (in the sealing above the amp) and therefor it comes washer fluid on the amp.
  2. Yes, you do. You need a special tester that can build up the vacuum to -400 to -600mbar in the brakebooster and then let it stay there. After a while you will read out the values and see if it is the same vacuum. To check if the vacuum pump is OK you will need a Porsche system test II. It will do the adaptations och se if it is OK. Take the car to a Porsche workshop =)
  3. Why so complicated? If you cant change the gearstick. Some signal is missing to the control unit. You have ABS and PSM fault aswell. You need signal from the brake switch to release the gearstick. If you are missing signal from that switch you cant move it. The ABS and PSM control unit needs that signal aswell, otherwise this alerts will come up. Simple test, Do the brakelights go on when you press the brake pedal?
  4. Possible fault cause (P1431) ♦ Leaks in brake booster system ♦ Vacuum pump worn out or mechanically faulty ♦ DME control module faulty
  5. With the car running, i believe you remove your old Nav DVD, then Insert Disc 2 in the Head unit till its done, then Disc 3 in the Head unit until done, then place the Nav DVD in the DVD drive. Remember that DONT TURN OF THE POWER when the PCM is updating. Doing so will cause software error and you need to replace the PCM.
  6. When you are driving short distances, the generator cant refill the power that are needed when the car starts. The starter takes a lot of power. Thats why I asked that question. If you are going at longer trips some times, then the battery will load up. BUT... If the battery goes almost empty a couple of times, it will be weaker. The generator are often in full function or broken in these cars. Nothing in between. Ofcourse some cars will have a half broken generator but I havent seen it yet. (worked with porsches for more than 3 years) If you can, try to put a charger over night and see if the problem are gone next time you start the car. If its gone, then its defenetly the battery.
  7. Check in your maintence book. I dont know how it is in the US but in europe its 30.000 Kilometers or every two years. Its the number you are first to reach that you should go after. If you read the book you should be able to see whats right for your car.
  8. You triggered an "EVAP system massive leak" CEL by not turning the engine off while refilling. These cars have a closed loop vapor control system on the fuel tank, running the car with out the gas cap makes it look like a vacuum leak. It should eventually clear itself after several running cycles if you do not repeat the mistake.............. Im not so sure that it dissaperas after a couple of driving cycles. IF the car has "EVAP system massive leak" the car has to light the warning up beacuse the ristriction of exhaust laws. Not sure about the US cars but they have more laws about that so I think it is worse with US cars.
  9. That was a low level of octane... here in sweden we have from 95 and up to 99 octane :D
  10. Hi, Just disconnect the connecter from the gray box. Just be careful, the valves can get stuck if you have it disconected all time. They are not for free :)
  11. If it is a model of 2008 the problem looks like a bad high pressure fuel pump.
  12. Did you have the engine on when you filled up gas? I suppose so... The gas system in the car needs to be closed (gas cap closed, etc) otherwise it takes in air and the control units gets faulty values. Go to a porsche dealer and have the warning removed.
  13. This faults are the most common when you have lack of power in the battery. The questions for you is, do you only drive short distances? Do you often let your car rest in a week or two? If you have answered yes of one of these two, I should replace the battery :) One more thing, do you have two batterys in your car? The dealer mabye changed one of those ?
  14. Its probabley the Pressure sensor that is the problem. Either broken or contact faulty.
  15. This fault can be displayed when the battery is bad. BUT, only if it comes up when you start the car. It can be the 4 wheel drive motor aswell. Check the battery first.
  16. In the Cayenne, you have a MOST line that goes from the PCM (head unit) to navigation unit, BOSE amp, telephone, tv and other external components that are connected to the PCM. When this fault (error) comes up, the MOST line is broken in some way. It can be the connections, yes. But most likely its one of the external components that are broken. When a externa component is broken, the MOST line is cut. If you want to test the components you need to have a MOST dummy that you plug in instead of, lets say the amplifier. If no error comes up, the amplifier is faulty. If it still comes up, try one of the other external components. If the amplifier is broken, check if it has come water on it. If it is so, then you should check the rear washer system for leakage inside the car. Sorry for my grammar but im from Sweden ;)
