Ok, let me explain in. The various modules in your car all have a version of firmware. If you are getting BMW to flash the modules, they will bring it up to the latest i-level. This involves flashing every module in your car.

This also defaults the module so any coding you have done is reset to default.

I just noticed that on my car, the passenger seat belt off light does not turn on when there is no passenger and nothing on the seat. When a passenger sits on the seat, the passenger seat belt off light turns on.... I've read that other people have this issue and it cost over $1200 to fix the sensor or it could be an old battery issue.

Thanks for the reply! I'm getting an estimate from BMW Portland here. If it's 1200.00 I think I will just let it go as is for a while.
