would cost anybody? i didnt drive it for about a week then when i unlocked the car and tryed to demobilise it, it wouldn't. the RAC have looked at it and said i got to take it to bmw. so i would like to hear from anybody who has had a problem like this
Put it on BMW's diagnostic computer and it will tell you the problem. Pray that all it needs is a computer glitch re-boot.
Otherwise you may need to take out a new mortgage as BMW have you over a barrel on this as it is unlikely that any independent tester has the details of alarms/immobilizers (too big a security risk!) for you to get a 2nd opinion.
