Mercedes a class door lock problem.

The door lock problem was discovered at an assembly plant in may 2017 but only one car had the problem. Insert the key into the ignition. Continue holding the lock button and at the same time press the unlock button five times. One of the common issues that are present in a range of mercedes vehicles is problems with the vacuum door locks.

Mercedes engineers investigated and determined riveting problems occurred at the supplier. Quickly remove key from ignition and within 10 seconds hold down the lock button. Next release all buttons and press the gate trunk button one time. There is a couple of ways to fix this problem.

If just one lock won t open on your mercedes then the problem may rest with broken wiring a bad solenoid or perhaps with a blown fuse. Vacuum door locks were invented decades ago and remain a part of many vehicle designs today. As noted mercedes owners share this faulty ignition problem more often than other drivers. However if you have never faced issues with vacuum door locks they can be tricky to diagnose and fix.

In older mercedes models an ignition key may be the primary method of starting entering and locking your car. Did you hear any signs of life whatsoever when you attempt to crank the engine. If so replace the fuse. Newer mercedes models utilize keyless entry remotes or key fobs.

The type of key your mercedes utilizes will dictate the route of diagnosis and methods of problem solving when something goes wrong with it. Check your fuse box first to determine if a blown fuse is keeping the lock from working. On those models the door lock actuators may fail causing the door lock to bounce up and down several times. This was done on a 2004 mercedes c230 kompressor sport coupe.
