For the future, Fudman's excellent door lock actuator DIY is here:
- How to properly maintain a door lock (1) & a DIY for how to replace the front lock door actuator (1) & how to disable automatic door locks (1) (2)

For the record, looooong ago my passenger side door lock actuator was intermittent. maybe one in twenty all-door locks failed. I'd have to physically look to see if the door lock actually locked whenever I left the bimmer in a parking lot. I brought it to the dealership, under original factory warranty, and they had trouble finding the error - but eventually replaced the passenger door lock actuator (as far as I can recall).

Never happened since.
Please read the suggested threads, where the best always add value to those threads, either by pictures or by descriptions, so the next person with the same problem stands on your shoulders.
