my local garage has had my car since 30/03/14 it failed MOT on tyre /seatbelt/emissions they replaced tyre & seatbelt but found that 3 injectors were failing ?.they allowed me to supply 3 recon injectors which they said were faulty after fitting these were returned to supplier who said that fault was due to metallic contamination ? after some discussion they agreed to replace injectors these were returned to garage they have refitted them car will not start after several visits & getting fed up with going around in circles i visited garage today 24/05/14 they say car is now running after they tow started it (i think they have refitted old injectors) they have also not returned original injectors as agreed to recon suppliers i am now liable to a surcharge for failure to return old units garage say they will return them 27/05/14 all my faith in car has disappeared & worried as to what garage bill will be HELP
