70K on my '12 R56.
About 2 weeks ago my audio/USB input stopped working. After checking a few forums, I decided that I should change the jack...anyway, audio plug had been wobbly for over a year, so I ordered a new plug.

Yesterday afternoon, I jumped into the car and voila!, the windows and turn signals don't work, my idiot light flashes from right door ajar, left door ajar, go see the dealer. Everything worked fine 30 minutes earlier.

This morning, I checked voltage (13+V), but I decided to clean the terminals and replace the battery. $200.00 later no change. Oh, and my audio/USB plug came while I was in the middle of all this, but replacing it did nothing.

I've read several threads on the footwell module, but there was no mention of the crazy warning lights (door ajar).

Any ideas folks.

Thanks
