My two front doors will not unlock, Only the drivers side with the key.
Rear doors will not lock/unlock
Strange but horn does not work either, all other electrics appear o/k
This is the second time it has occurred, first time under warranty and garage (Sitner BMW) stated fuse blown. Now a week out of the three year period it happened again horn?
Changed and swapped all fuses listed on the fuse chart associated with the locking but no effect.
Help, any one update me on where to look on a current series three? Or fuse number to change apart from as listed on the fuse card.
