just recently had the front passenger side lock actuator changed from the dealer. but in under 24hrs it started doing the same thing "wouldnt unlock or would'nt lock" even tryied to pull the door lever from the inside still wouldnt unlock. Do you guys think that since they replaced the lock actuator, and the problem is still there. It might not have been the actuator but something else. Has this happened to anyone else before? i have a x5 4.4 01
