I took my car to an audi specialist for a full service, cam belt change, water pump, drive belt etc... Well at the end of the second full day he phoned me and said theres a problem with my car!!!! He said he put it all back together started her up and she was'nt running right so he's had to strip it all back down because the tensioner wheel was out of sync. Should i be concerned and could he have caused any possible engine damage by starting her up and the cambelt not going correctly. Your help would be appreciated as i have to go to the garage tomorrow morning and ask him what the **** is going on. Thanks.
