I have a mk 1 Leon SX 1.6 and about 3 months ago i discovered one of the rear dorrs would'nt lock at all, MOT was approching so my mechanic managed to get that door to lock but now the passenger door wont respond at all, either with the fob or control panel on drivers side, its a real pain cos i am unsure if the lock has had it or the ECU that controls everything, anyone else had this problem?
