  1. you solved this problem for a lot less dollars than it cost me. I guess that's the price one pays when one is not mechanically inclined and dependent upon the expertise of mechanics.
  2. getting back to this post as per the suggestions of one on the mechanics that has been working on this vehicle for many months. I am now assured this intermittent starting problem is totally fixed. I did receive an unlimited mileage 2 year warranty on the entire starting system from the owner mechanic when I picked up the car today. 2 additional problems were found which has now corrected the intermittent starting problem that I previously experienced. first was a cracked PC board next to the fuse block. the second, perhaps bigger problem was the connector w
  3. the mechanic had suggested replacing the grounding strap (which is what I believe you are referring to as the earth strap). is this something that is under the carpet just in front of the driver's seat? thanks for your input, much appreciated.
  4. I appreciate your advice and will act upon it to have my mechanic check the wiring. it does make sense that extreme heat could cause a brittle or partially non-insulated wire to ground out against another wire or metal part. the car is a 2005 so 12 years old. however, why is the Rockford portable battery starter able to jump start the car when the car will not crank on its own when the ignition key is turned? I guess it could be a wire from the starter relay to the battery such that when the key is turned the relay "sees" no battery, and when the Rockford is put in place now there
  5. OK, 2005 cayenne turbo. intermittent problem with starting. had independent Porsche mechanic replace the battery, alternator, starter and starter relay about 9 months ago. very intermittent problem which happens about once every 3-4 months. seems to be more pronounced in very hot weather (90-100 plus degrees Fahrenheit). when it happens the engine simply will not crank at all. in spite of that I will still have radio, horn, power windows, AC, etc, full electric. in the past I have simply used a Rockford battery jump starter (given to me by the mechanic) and this starts
  6. I appreciate your input. quite honestly I have never personally performed any work on my vehicle. a non-Porsche mechanic described using AC pro as simple as putting air in a tire. apparently AC Pro contains sealants as well as refrigerant. thought maybe this would work sort of like fix a flat. I guess you can already tell I'm in over my head, lol. last thing I want to do is attempt what appears to be a simple repair and in doing so cause a major problem with the AC system. my reluctance to proceed in spite of the encouragement I'm receiving from others caused me to shoot this query
  7. has anyone ever recharged their AC? I have a 2005 Cayenne Turbo. I noticed the other day the AC is not as cold as it used to be. Has anyone used AC Pro to recharge their AC? I believe the refrigerant is the same as what Porsche uses. Is this something that a novice can attempt, or will this damage the AC system by using an after market refrigerant that is not from Porsche?
