Yesterday a "Third Brake Lamp Defect" message showed on the instrument panel of my 2008 E320 BlueTec. It may be a total coincidence but now my trunk lid can not be opened w/ the switch in the drivers door or by hand at the lid itself. In other words I can only open the trunk lid with the metal key in the ignition key. I figured that one of the bulbs (led's?) might have burned out so I started removing the inner trunk lining. I am currently pretty far away from home so I don't have any tools and with the lining half removed I still could not get to the "Third or Center Brake Light". Or should I try removing the light from the outside? There are no screws visible though.
Can anyone tell me if there is a correlation between the Center Brake Light and the Trunk Lid mechanism?
Any suggestions and/or advice about this issue is most welcome.

Check wiring to left trunk hinge: https://mbworld.org/forums/e-class-w...ate-lamps.html

Probably the wiring like konigstiger said. Do the red buttons for closing the trunk light up?

Thanks but no red lights when trunk is open or closed

Many thanks for your response Konigstiger. I am back home now and will start the repairs tonight. Hopefully i will be able to locate the broken wires.
