Have Mercedes Questions? Ask a Mechanic for Answers ASAP
on this car everything needs to be matched up , the modules and the computers . Once you fit in a car , you can't put it back in an other one ... It's sad to say but you will need to get it fix with a new one :(. Some shop are able to install it and program it , you need a special key from Mercedes to light up the ignition switch and then the key can be learned with the new ignition !
