Guys,
My electrician has replaced the sensors and it seems like the main problem is the Combination control module, which i believe is also known as the main computer or brain. Please can anyone guide me to a spare one. I live in the UK.

Cheers

check used car parts places - it be a long quest but you should be able to find a used CCM for cheap

Are we talking about the fuse box, the ECU or something else?

If it is the ECU it is vin coded to the car it came from and you can not just go purchase a used one and plug it in.

Good Luck. I am afraid the price is going to suck for you though.

This place in the UK fixes ECU for about 5% of the cost of a new one.

I think ECU and CCM are two different things ? Don't have my Mercedes CD with me now.
