2014 W212 Tail Lights Problem
Hello everyone, my car's right outside tail lights is not working. (Brake, signal and reverse lights are ok). Before, sometimes it used to be has problem but when I restarted the car then it was working. But now it never works.
When I hit the tail lights it starts to work but after a short while again it stops to work.
Here is the video link about it and also I share my own car's photos.
Is anyone having this problem? And also does anyone know the solution?
Thanks for your answers and helps.

just replace the light. It’s cheap; less than $250

Hello from Portugal. I have the same problem. It started with one light (a few weeks ago) and now both rear lights have the same default. I think the problem is not with the light, but something else related to the electrical part of the car.

Hello,
Resurrecting this thread because my taillight just started with this intermittent foolishness. If I smack it, it lights; then sometime later goes out again, just like the original poster. Anyone find a fix for this yet, or at least a way to check for failure? TIA!
Edward

The beautiful rear facelift W212 LED lights are built with amazing solders to fail.
Either replace or repair the bad unit then consider the opposite side to fix the same excellent feature.

A broken solder joint, several YouTube videos on how to fix. I would desolder all joints with leaded solder because lead-free solder is brittle anyway. This is why modules in all cars, not just our beloved Mercedes, fail so often.

Thanks to the work of others I was able to see the position of the resistors
So all I had to do was mark it with masking tape, drill a couple of holes to access the resistors to rework the solder joints
I used a drill press for better control of the drill bit because there are wires underneath that you don't want to nick
I drilled a 6mm pilot hole and checked what was below and could see the resistors
I then redrilled using a 12mm drill bit so that it just broke through the plastic
Then it was easy to get my Hako 936 temperature controlled iron in
I set it at 400C degrees, reworked the joints. Tail light repaired
Taped over the 12mm holes with electrical tape
Fixed it back on the car, plugged it in and all worked ok
Job done
