  1. Update I updated the firmware on my iCarsoft and reran code check. Now I’m getting the following code on the panoramic: — 0470 CAN comfort in single wire operation also I’m getting the following error on the Gateway: — 1336 CAN comfort OFF would this info help in my search for the grounding problem?
  2. If I have changed out the battery, how do I reset the electrical system? Thanks.
  3. Hello everyone! I’ve run into some electrical problems on my '08 Turbo and I’m stumped.... I've looked through a lot of Renntech posts and don't see any thing close. First the panoramic roof and sunshade were opening and stopped about foot open. Maybe coincidence, it happened right when someone opened the door. I’ve checked practically every fuse even pulling the pano-roof control unit (back where the motors are located, and the circuit board looks okay. Then the instrument panel has started to act strange. The gear indicator shows that it is all gears at once, see the photo which is while it is in drive and moving. I can shut the car down and restart and the problem goes away. The time keeps changing randomly and the outside temperature is wrong. The button that opens the rear hatch that’s on the driver door has stopped working. Then my battery died, it was five years old so no surprise. After I replaced it the airbag indicator on the panel has lit up. I’ve tried to reset the instrument panel (Main Menu> Settings > Factory Reset) but it will not allow me to select “Reset”. I’ve also pulled the fuse several times to reset the panel but no change. Today, I’ve connected my iCarSoft POR II diagnostic tool to the car. The Airbag section says it “cannot connect to the ECU” so I can not reset the airbag light. There are YouTube videos of people using the tool on Cayenne’s (albeit on newer models) to reset it so I believe I can. The Panoramic roof says it does not have any DTC codes. The lift gate button on the driver door indicates it has appropriate voltage and no DTC codes. Also, no DTC codes for instrument panel, electrical system or DME I’m not sure this is related or not, I changed out the interior incandescent bulbs with LEDs. I now know that LED bulbs give off electromagnetic interference but seems remote. (as a side note, I found this out when I put LED bulbs on my garage door opener unit and it stopped receiving commands from the remotes – I had to get special bulbs from Amazon) Yesterday, I removed all the LEDs and went back to the old bulbs – no change. Any ideas, suggestions or guesses? Thanks, Mike FYI: The car is in Drive, "D" and is in motion.
  4. Thanks for the info Loren. Any suggestion on where I should have the technician start?
  5. I've been receiving codes P1372, P1353 and P2404 on my 2008 Cayenne Turbo. I've tried clearing them and they keep coming back within 10miles. After running for 50-75 miles or so, the following codes appear, I assume they are caused by the first two: P0174 P0172 P0300 P0424 P0301 P0302. I took into the dealership to get it fixed. They said I needed replace my camshafts (948-105-051-14) Hydraulic Valve (948-105-304-07) and Valve Assembly (948-105-308-03) on both sides for a grand total “starting at” $7400. It sounded like it was a partial exploratory expedition. I said no, and asked for alternatives. The tech told the service manager they it could be sludge buildup causing the camshaft to be out of sync and I could try some type of oil additive to see if it would clear up. I did try Seafoam in the oil (yes I know) for 200 miles with no change. I also changed my gas cap in hopes 2404 would clear up, didn’t work. I plan to take it into another shop tomorrow. I’ve read the diagnostic information Loren provided above but not sure what the fix is or if the other codes tells a different story. Thanks for your help!
  6. I can lock/unlock it with the key-into-door. I did play with it yesterday and realized I was partly incorrect. When I unlock with the fob, the driver's door unlocks then re locks but the pax door unlocks and remains unlocked. I will check out the LED and report back (this weekend). My oddments has a retro fit on it to make it bigger (long before I bought it) so I dont think it is hooked up anymore. Thanks again.
  7. :welcome: You will likely need the Durametric software, a PST2, or PIWIS tester to see what central locking/alarm faults you have. Do you get any beeps when you lock the car with the key fob? No beeps but it has never beeped. I will need to fine a tech in my area with a tester.
  8. When I use my key fob to unlock my '98 boxster, it unlocks then 0.5-1 second later re-locks (both doors). The same happens when I try to lock it; it locks then unlocks 0.5-1 second later. I didn't come up with anything when I searched the forums. Any thoughts?
