Mercedes lock door with engine running.
Lock mercedes benz while engine running.
On those models the door lock actuators may fail causing the door lock to bounce up and down several times.
Then briefly press one of the buttons to completely open and close the door once.
Unfortunately i had some problems with the mercedes a glow plug went out and i decided to have all six replaced at the same time and after 6 years the vehicle battery failed and i had them replace the rv batteries at the same time.
If you turn the key from man position back to auto you must reset the sliding door.
Mercedes benz vehicles such as e c s ml gl r class are designed to automatically lock the doors as soon as you start to drive.
Lift up on the auto up driver window switch.
There is a couple of ways to fix this problem.
Roll down the drivers side window.
Ive done it by starting the car open drivers door hit lock button on door then use metal key inside fob to manually lock the driver door.
Open the door and exit the car.
Only way i know how.
Drivers can lock and unlock the car just by touching the door handles.
Pull your arm out of the car before it gets pinched by the closing window.

To do this fully close the sliding door once with the button on the centre console or in the doorway pressed down.
Lock works perfectly now.
