Rear LED signal light problem
Hey all car is a 2009 C300 4Matic has rear LED turn signal lights.
I had the bulb board and connector burn out on the right side so I replaced those. Now the problem I'm having is the right LED signal blinks once or twice then switches to the bulb above the LEDs (I think this is the marker light) and uses that for a signal instead. It does this every time I signal right and I'll get the check rear right signal error on the dash. I don't see any blown LEDs.
Any ideas?

I don't understand what you mean. The parts I replaced have the same part numbers as the originals and I did each wire one by one not to get them mixed up.
