Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hi, my name is***** fault code and the fact that you have no gear display on the dash indicates that you have a faulty electronic gear selector module. There is no standard reset for this code. All you can try is disconnecting the negative battery cable for 15 minutes to see if it will reset the module. If you have no luck you will need to replace the gear selector assembly. The transmission slams into gear because it is not receiving the selector lever position from the gear selector module.
