Hi,
I am seeking some advice please.
I replaced a deployed driver airbag in my 04/2002 C200 Kompressor (the early model) and the replacement horn pad had a different connector as it came from my other car which has the later model contact unit.
So, I changed the circuit boards and replaced one of the switches whilst it was apart, and an auto electrician checked it. It now has a replacement steering angle sensor and airbag, but when I touch the horn pad, the display on the instrument cluster changes, and the functions of the switches are reversed.
Would this have anything to do with an aftermarket stereo with CANBUS being installed, which is not happening for the other Mercedes we have (same model), or do the replacement switches (including horn function) require reprogramming, or can I safely assume that the circuit board, or horn circuit was damaged when the airbag deployed?
It looks like I need to buy a complete horn pad.
Thank you.
