LEDs in a 2007 w204???
I'm looking for some help. I’m new to owning Mercedes cars. I’ve recently bought a c220 cdi 2007 and I’ve just fitted led bulbs to my headlights including sidelights/parking lights when switched on they flash on and off a few times then switch off altogether. The sidelights/parking lights stay on but are extremely dim even when the switch inside of the car is off. The warning messages come on on the dash/clocks any help is much appreciated
There are a lot of threads in this forum that deal with what you are trying to do and they usually involve changing o rre-coding the SAMs.
I have a similar car to you and I think the hassle is just not worth it.
Just enjoy having a reliable OM646 engine and no DPF. :-)
