On my W208 230 clk the main beam and headlight flash has stopped working.
I've checked fuse's and earths and they seem OK
Anyone come across this before
I think it's just the light/indicator stalk, cruise is separate, but an MB parts counter will know.
Don't replace it unless you're sure though, it could be an ECU/Relay, get a test light on it 1st. Have you power @ the fuses?
I don't know if the W208 CLK is the same as my W203 C Class, but high/main beam does not have a fuse, it's controlled electronically by the front CAN BUS. (None serviceable).
I would suggest you get it checked out before you start throwing parts at it.
CAN is an acronym for Controller Area Network. It is a digital communication protocol for the various systems in the car.
