In anticipation of a worse case scenario I rang my local BMW dealer today to see what they would say. When I described the symptoms they said it was most likely that I had damages the FRM (Footwell Module?) and that I would probably need a new one and that would be about $2,500 AUD and that it would probably take 2 weeks to get one out from Germany. I was interested to hear them say that my windows probably would not work but that is not the case. The windows go up and down fine and the headlights still work but not the interior lights. The things that do not work do not seem entirely consistent with a failed FRM. I would be interested in your opinion.
