2006 Mercedes-Benz S500 ProblemsClosing Assist/Door Lock Issues Due to Pneumatic System Problems
Problems with the pneumatic system can cause closing assist and door lock issues.
The crankshaft position sensor may fail. Symptoms of this are: The engine will crank—but not start—especially when the engine is warm. The car may start again if it is left to cool off, but it may run roughly or have poor performance.
The evaporator temperature sensor can fail, causing the AC compressor not to cycle. If the AC compressor does not turn on, the AC system will not blow cold air. If the compressor is stuck on, the air will be very cold at first, before warming up.
2006 Mercedes-Benz S500 Questionshow to find if automatic trunk assistance pump is bad or leak in system? (1 answer)
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.
