central locking tied to brake pedal?
 

Ok 1995 850t, bought it 4 years ago and has always locked the doors when A: you press the brake pedal (if i do this and haven't started the car i have to unlock doors with remote or key in door, B: car running open any door all doors unlock, if you open rear hatch all doors lock yes i've locked the keys in the car because of this...)

today it started locking doors when you press break pedal and unlock when you let off the break pedal ( i pulled the central locking fuse) also he lamp overload light in dash comes on when you press break pedal, but i can't find any burned out bulbs this started at the same time as the locks...

anyone have any ideas

Sounds like there is an aftermarket Alarm in there somewhere that is messing up.
