I have a W212 which is all LED, so not entirely familiar with W210.

But: You would not have installed a dual brake/tail light globe wrongly in its socket? That can give some weird behaviour.

Other than that: could it be there is some biodegradable wiring in the mix?

Hi Bart
thanks for tghe reply
yes can be an issue but disconnecting and removing both rear light assenblies should eliminate that possibility
removed the sockets .middle brake light still on
remove entire assemblies .. still center brake on .... doh

getting new car for wife
and probably sell the w210 . if it can be fixed

they thought brake switch first .then headlight switch/fusebox
and ended up being in rear right brake light .

W210
Tail light assemblies - all the bulbs are subject to the screw in holders corroding.
Every now and then need to remove the bulb assemblies clean them up, make sure tag tensions are Ok and re install.
