Hello all - hoping you can help me through the next set of issues with my 2005 S500 4matic...
My central locking system, trunk release, rear seat headrests and soft-closing doors/trunk are all giving me issues. The buttons on the dashboard for the central locking, unlocking, and lowering of the rear headrests are inoperative, as is the trunk release on the driver's door. Also, the central locking system does NOT automatically lock when in drive and rolling forward, as the setting in the cluster calls for.
With the remote key fob, the "lock" button activates the alarm, but no longer actuates the locks themselves. If I manually lock all four doors, by pushing down the locks on front passenger and both rear doors, then locking the driver's door with the key, the "unlock" button on the key fob will actuates and unlock the front driver and passenger doors, but neither of the rear doors.
The trunk, which I believe should have a "close assist" is not working, and the "handle" - the air actuated polished stainless "tongue" - is stuck out, in the extended position. When any of the aforementioned items are called to be actuated, the PSE pump does run, I can hear it clearly. I do NOT hear any leaks anywhere. Last, none of the four self-closing doors are working either.
Earlier this week, things were functioning normally, locks were locking, trunk was popping, however the tongue was out and the self-closing doors nor trunk were not working. I had the interior detailed yesterday, and upon picking the car up, nothing worked. I assume they had the trunk and the doors all open for the 5 hours they had the car, and God only knows what else they did.
I did attempt to "reset" the system by removing the 20A yellow fuse, #62. This did not accomplish anything, nor did clearing the PSE system codes with my iCarSoft MB-II scanner/programmer.
I know the PSE has been covered extensively, however it is very difficult sifting through all the threads, and while so many seem hopeful, it then often seems the original posters has fallen off the face of the earth before answering the members!
Any help as always is greatly appreciated - I don't mind turning my indie repair shop loose on the car, but I always like having a little direction beforehand so as to cover my butt in the event of. I hate senselessly throwing parts at something and hoping for the best, as so many shops try to do.
