Hi guys, just bought an ML270 CDI, 2003 facelift model. I've noticed there seem's to be a fault with the headlights stalk in that, the main beam trigger seems to have a mind of its own and will flick between main beam and low beam by itself, but most of the time it just stays on full beam which means I've had to remove the full beam bulbs for now.
Also the side lights at times will stay on by themselves with the switch at position "0" and in order for me to get them to turn off, I have to put the key back in the ignition turn ignition on then off again and side lights go out.
I thought the fault might have been might with the stalks, so I purchased a brand one and installed that, but the problem is still there. I have checked the relays and all seems fine there too.
I also noticed that with the lights off [position 0] when I push the stalk forward [as in full beam on] the instrument cluster/dash light come on!!
Just wondering has anyone got any suggestion? or ever came across this before?
