View Full Version : Question Rear Right central locking issue

17-06-2018, 09:05 PM
Hey all,

My old mans Audi A3 8P is having a bit of an issue with the central locking on the rear right door. When you unlock the car with the remote it unlocks three of the doors and not the rear right. We replaced the locking mechanism and this has not solved the issue. We can hear the new unit clicking when the key is pressed. It also locks correctly.

The door can still be unlocked by pulling the internal handle.

We have checked the cables at the plug break going into the door and all seems okay with no visible signs of damage/chaffing/broken. The window motor works correctly, as well as the speaker.

We are at a loss now as not sure what it could be, I would check for continuity of the cables but without the wiring diagrams available this is a struggle.

What do you guys think could be the issue?
