New to the forum as an active member!!! This is my first post so excuse me for any mistakes. To the problem now. I have a Cayenne 2008 GTS with 380,000km !!!!!!!!!!!!! On saturday i washed the car and since then various problems started appearing. I noticed that the car wouldn't lock with the remote nether unlock so i thought to my self that it is the remote battery despite the fact that i had no warning on the cluster.
Next day morning i tried starting the car and it started fine but the "Check Tailights" warning came on. Got off the car to check the lights and they didn't work. I tried opening the boot to check the bulbs and i discovered that the rear lid wouldn't open either.Also as soon as the car starts the Alarm starts singing, not very loud though ( if my car was to be stollen i wouldn't hear the alarm, thats how low volume it was)
So besides the locking and unlocking problem, taillights the rear lid problem appeared.
I thought that it might be a fuse so i checked all fuses. Left and right fusebox and the one in the engine bay. All the fuses were ok. I plugged in the Durametric Proffessional cable and i come up with the fault code "1330 Rear convenience system control module - No signal/communication, test conditions are not-completed, fault is not currently active and is not causing a DTC light"
I did a lot of online searching but couldn't find anything specific. My guess is that i need a new Vehicle Electrical System Control unit. Any ideas? Has anything similar happened to anyone? I am out of ideas and the Dealership here in Cyprus is no option. I used to work for them :) so i know whats going on!!!!!!!!!!
Any info would be greatly appeciated!!!!
P.S. Hope my post is ok. Dont want to be banned on my first post!!!!
