C-Class Tail light stops working for a while

[AngeloOliveira]

Hi, good morning!

My MB C200 2008 has a problem;

- The tail light (hazard light) right or left stop working AFTER a while, then when I turn off and turn on the car (engine) it works normally for a period of time.

Some times the fuel marker stopts working too.

I notice that if it is too hot, like 100 F° or 35 C° (I live in Brazil) the problem is harder. Looks like some piece stops working and get works normally after turn off the engine.

I dropped the car at 2 garages but always the same problem, thay say that uses the scaner (do not know de kind).

I made a video to show the problem, attached.

Im really disappointed!

It's an electronics problem. Either the ECU or the circuit of the lights knob. Everything that's solved with a restart is an electronics problem.
