Ok so my car was serviced at BMW and they gave me a list of jobs that needed doing in order to pass the mot, had to get rear tyres changed, brake fluid replaced,rear bushes and airbag control unit, now I'm looking at a bill of around £350 for the airbag unit to be sorted through BMW , is this something I have to get done through them or are they just playing d1ck Turpin and robbing me? As they wanted just shy of £500 for two rear tyres so I went elsewhere!
