mid april this year i presented my car for mot to be told it had failed on emissisions the scanner they used was not working correctly ? so they done a bleed off test which revealed 3 faulty injectors after they quoted £200. per injector plus fitting i asked if i could source my own recon injectors this was ok with garage i sourced recons which garage fitted the car then failed to start they said recon injectors were faulty so they were returned to supplier they have said that the fuel in injectors had metallic contamination so warranty was void they say that fitter should of carried out a fuel test before saying i needed injectors? the garage say that they did carry out fuel test & no contamination found the supplier has now said as a act of goodwill they will repair contaminated injectors free of charge but will not accept any returns if contamination issue is not solved the garage now has the recon injectors back from supplier i visited the garage again 10/05/14 to find that the car is still not repaired they say they have not fitted recon injectors because they have now found metallic particles in fuel tank ? they now suspect injector pump? have walked out of garage to get advice as to where i stand i have obviously been lied to by a established garage can any one help?
