I recently booked my car in for a service and MOT and our local BMW dealer, after i had it MOT'd it failed on excessive play on a track rod end, they also mentioned that 3 tires were close to the legal limit and would need replaced soon but were good enough to pass MOT, once the track rod end was fitted they said i would need tracking done again, then they said that their tracking machine could not work because tire tread was too low. so had to replace 3 tires with new run flats which cost in excess of 600 quid, just never heard of this problem before, i work away from home and it was actually my wife that too the car to the garage. anyone have any input /advice on this issue. I just don't trust garages and feel a bit duped, justified ? i don't know.
