I have just had my car in to a specialist garage for an MOT. A front suspension coil spring & a new steering rack had to be fitted to pass the MOT. When I collected my car, it was driving really flat & had no power. It has never had this fault prior to this & does not recover after turning off the ignition like some posts on here. I believe that the garage has created this fault during this work & I'm in dispute with them. Am I justified in saying this or just unlucky. Any thoughts ? The car has covered 75k miles by the way.
