My central locking system for the doors won't work and my trunk will not close.
trunk lid does not get pulled down all the way. The passenger door does not lock with all the others.
problem with closing/assist on doors.
Had the same problem occur about a month after I bought the car brand new. Called MB Roadside Assistance; they did something to override the security system. Car brought to dealer. Problem due to a leaking hose in the driver seat lumbar support which is connected to the same pneumatic system. Wow; the lumbar seat control caused the security system to prevent using the car on a dark, lonely parking lot after work late one evening! "The best engineered cars in the world"???
closing assist doesn't work, But locks and trunk does. How do I find leaking hose?
Power door locks stopped working
When I hit the Key fob I get the indicator lights like it is unlocking or locking but nothing locks or unlocks. The trunk lid lever does not push out as normal. I have to manually lock the doors and the trunk. The lock switch on the dash does not operate either. What might be the issue. I replaced almost all of the fuses in the trunk also.
Power locks and trunk door open do not work
The rear doors do not use the neumatic final boost to close tight. The have to be slammed.
Same problem, hear a sound from passenger side, but remote won't work for car locks and trunk.
Closing assist/door lock not working
not able to lock my car with my key remote and my trunk wont shut like it should and handle wont come out anymore how do i reset it
key will not lock or unlock door,s automatic.
The trunk as well as the driver's and passenger side doors don't shut properly i.e. Closures by suction or vacuum, which is how its supposed to shut. You can forcefully shut the front doors but you can't shut the trunk without the vacuum.
my doors were not closing, I had to slam them shut. I disconnected the battery and allow the computer to reset. the doors works just fine now.
havent remeid problem yet
Have had some issues with vac close assist especially on the trunk. The pop out trunk handle will not pop out. Now all the doors except the drivers door are locked & will not unlock. The trunk handle will not pop out. The trunk button & the door lock button on the dash are not working. The auto locking feature when you drive over 10 miles an hour is now not working on the drivers door
Mercedes-Benz S420 : Closing Assist/Door Lock Issues Due to Pneumatic System Problems
Heard a snap when closing passenger door. Now door closure assist does not work on this one door. All other doors work fine. This one must be slammed to close tight.
