2006 Mercedes-Benz S500 Problems
Problems with the pneumatic system can cause closing assist and door lock issues.
The relay which turns the airmatic suspension pump on may fail causing the pump to run continuously. This can result in failure of the pump motor or a dead battery as the pump motor will continue to run after the car is turned off. Also, Worn airmatic pump mount bushings can causes noises in the front axle while driving on bumpy roads or a buzzing noise while the pump is running.
The door for the vanity mirror (or the frame for the door) can break; due to a redesign, the mirror "cassette" will need replacement.
2006 Mercedes-Benz S500 Questions
I have a 2006 Mercedes S500 doors nor trunk responding to key or door switch lock and unlock command. Head rest non responsive also. Automatic trunk assist pump in trunk has fluid but makes no sound while pressing button on key or trunks manual open button. How do I find and fix this problem?
Trunk opens normally with key fob or door switch but only stays open for 5 to 10 seconds then closes on its own. First reasonably slow/soft then quite firmly when the trunk assist engages.
locks on all doors are functional,key fob works on all doors but right rear will not open.
