On a project C63 car ive been working on, i was shocked to see a c300 module installed. Car has semi power steering working(loosens up as i drive), sport TC mode is not active, there was red hood light but my mechanic was able to code it out besides that car is 100%. So I was told the c300 module cant be linked to the c63 to restore back the power steering to 100% and the sport mode to come back, so currently in search for a c63 module that has a blank vin which the seller can attach my vin to it for a easy install. i would have liked to program the c300 module but it seems like it would never work properly.

Is there any reliable sources here for this job, and part.

I wish i had the original module but it is what is.

The original part number is A0375456332

The one on my car now is A0375455332

My original plan thinking that my car had a c63 one in it was to just send it out for repair, but seems like the last owner caught me on this one lol, but then again who checks a esp module VIN number before they buy a car to see if its the original one.
