One problem related to power door locks not working has been reported for the 2003 BMW Z4. The most recently reported issues are listed below.
Passenger door lock will not unlock with the key fob or the interior switch. All other locks respond appropriately. The door will open manually with the interior handle. I replaced the lock actuator with no improvement. I am now trying to replace the electrical relay. The date below is approximate. I am the original purchaser. I have not been happy with BMW service department.
