c43 amg from 2000 had shift buttons behind the wheel.
do you have the same steering wheel smaller sporty type like on the c43 minus thick grip without perforated leather ontop?
do you have SPORT trim on your car, then you should also have the smaller type steering wheel?
I meant when CEL lights up in cluster there is something wrong with the car, you have to check codes.
no illumination from CEL all is good with the car
