    Hi all

    New poster here. My car is a c204 c220cdi.
    A little puzzled as the bulbs have not gone...
    Driving home yesterday and got this error message "Right-Hand tail lamp / brake lamp" message. Any idea?

    The bulbs seem to be ok, the connections too and bulbs have not blown. The bulbs holder has not burnt/ corroded away as I have read somewhere. Any ideas

    Thanks
    Ravs

    Have you checked with the brake pedal depressed?
    Be aware MB uses a substitute lamp should one fail

    Had a similar issue with my old E Class and found it to be a dodgy bulb. I foolishly replaced earlier with a cheap bulb not good quality bulb.

    Most likely this ^

    For example, if the tail lamp fails, the car runs the brake lamp at low power to provide tail lamp illumination.

    What I'm saying is that the most likely cause is that one of the bulbs has failed so you should pop them out and give them a proper check. When you say that "bulbs have not blown" is that by examining the filaments / checking with a test meter, or that a lamp is seen to illuminate?

    If you find a filament blown (typically it's one of the two in a combined 21w/5w stop and tail lamp) then replace; if all is well with the bulbs then you will need to look elsewhere.
