2006 Cayenne V6 Base model (sorry long story)
I bought this vehicle in June 2014 and I replaced the battery in late July.
On July 30 a forest fire came to my home, the Cayenne was in driveway as the fire approached.
When the fire got closer to the house I moved the Cayenne to the other side of my house near front door.
I put my dogs inside and opened the windows about 6 inches each, I also left the AC on.
While moving car to front of house I had to drive over front lawn and a small retaining wall when it tore a rock loose.
Firetrucks and fire was blocking driveway.
The fire was about 20 feet from the house & the Cayenne was on far side when the helicopters arrived with huge bags / buckets of water. They started dumping water on fire, house and ended up hitting Cayenne as well.
The helicopters kept going back and forth dumping water for about 3 hours pushing fire away from my home.
After fire was pushed away, the car was still running fine, I finally shut it off when I knew I was safe from the fire.
2 days later I went to drive it, it was raining and the AC and wipers kept turning off for a second or 2 and then came back on.
I called insurance company and they took it to Porsche. When tow truck arrived the new battery was completely dead.
The dealer ended up replacing the Transmission module clearing the drain plugs and replacing the sun roof headliner.
No mention of water.
When I got the vehicle back, it seemed fine for about 100 miles, then the AC issue came back along with the headlights flashing when in the off position, when turned on they did not flash.
Then it seemed like the car would shut off according to the gauges, the radio would shut off the windows stop working the alternator gauge would drop to 0. the cruise control stops working, then will all come back on again.
The car would flash a warning "System Fault Workshop" with a diagram of a key above it. \
The tach and speedometer keep working and the car stays running just fine. The oil pressure does not drop nor does gas gauge or temp gauge, they all keep working.
The turn indicators inside work intermittently while outside lights working fine. When car is shut off, sometimes tail lights stay on and sometimes courtesy lights stay on.
Insurance company brought it back to the dealer for repairs, the dealer 1st thought it was battery without checking with me and replaced the battery, they then thought it was the key, so they replaced the key but did not program it! ???
Next they thought it was another module, then they said (after 1 month) that there was water on the floor boards and that the repair would cost $18,034.37 plus tax to total $21,004.80. They also had an estimate for $28,221.62, for complete repair with labor.
So insurance company decided to total it and give me $1700 while paying off loan.
I said if I was only getting the $1700 I wanted the car as salvage as well.
Insurance company came back saying they would not total it and give me the car + $10600 to get out of claim.
I accepted this offer because I knew the car was still running just fine, it just has gremlins. (or bad module?)
Now it is for me to fix. Here is what the dealer said would need replacing;
955-610-127-02 Control Unit $336.13 Gateway
955-618-040-12 Control Unit $280.85 Trailer
955-618-036-05 Control Unit $527.17 Immobilizer
955-641-113-AX Instrument Cluster $1995.28
955-618-601-10 DME Control Unit $1354.25 Engine Control
955-618-020-21 Control Unit A $554.58 Automatic Transmission
955-618-027-01 Control Unit $420.13 Body control
955-612-913-05 Wiring Harness $410.92 Sub -P Front Drivers Side
955-612-914-05 Wiring Harness $410.92 Sub-P Front Passenger Side
955-612-901-00 Harness $15695.52 Passenger Compartment
955-618-518-03 Rain Sensor $264.51
I do not really believe all of this needs replacing, I think they did not want to work on it and gave a high number so they would not need to repair it. (maybe I am wrong). I drove it home and have driven about 200-300 miles so far.
So any ideas where to start?
I have been able to rescue control modules after they have been in water using distilled water gently cleaning and the drying in air and then a few days in a bag of rice.
But again where should I start?
thanks and sorry for long post.
