Hi guys. Had a problem with the seatbelt buckle for a while. It doesn't click the belt in place unless I really slam the release button down hard and then it will allow the belt to enter the chamber and then let go of the release button to lock it in place.

My question is: can I replace the buckle part of the pretensioner from another BMW (I know someone has one from an e90 but the wiring is busted for the pretensioner) to solve the issue as I don't want to really remove the seat to replace the whole pretensioner.
