How to fix a non-working central locking on a Mercedes

Model: Mercedes Mercedes Various
Part: Body

Video tutorial

If the central locking on your Mercedes is not working and makes the characteristic "machine gun" noise, this video is for you. Remove the cover of the front handle; it hides two Torx screws that we will remove to free the entire panel. Once these two screws are out, the panel is held by clips, so carefully pull it off, being mindful of the clips and rear connectors.

With the door exposed, remove the lever on the left: replace it with a cable tie and reattach the nozzle. Check your spring supply (if you have one; otherwise, you will need to obtain one of the same size as shown in the video to replace it). Attach the spring to the cable tie and secure it by making a hole near the bracket.

Refit the panel and test the central locking. It should now open and close normally.

Job done.

How to Remove the Rear Seat of a Hyundai Tucson?

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat. Be careful of any electrical cables or components that may be connected to the seat during removal. Once the rear seat is removed, the disassembly is complete.
