MDM button no longer functioning
I have an E90 M3 owned since new. In the past month the MDM button stopped working. Doesn't really bother me but I still like my stuff to work (I never use it except first run out on the track IF it's raining).
When I check fault codes I get a "MDM receiver fault." Cleared the fault and it's coming back pretty consistently as now, "MDM Control Module fault." It give me a part number (my Schwaben code reader) 7848125, but I can't find any parts supplier that recognized that number. Does anyone know 1) Where the MDM control module is located. 2) What is the part number 3) Do I have to code the vehicle for it to work (my guess is yes). Appreciate your input. |

Mdm is controlled by the switch unit.
