Do you have the BAS function on your c43?
The stealership could not access to this with their star computer, they say either it's broken or i dont have this option on my car.
A broken breaklight switch does it have anything to do with BAS function, i had it replaced 2 days ago.maybe thats why the staelership couldn't access with their star computer it didn't give any response? could it be this way?
thank you
DAS usually has some trouble communicating with BAS during a "short test", but it's ok during actual diagnosis. Just one of those weird things computers do.
To convince yourself just go out and perform an emergency stop and see if it works as it should.
