That happed at the old branch to my own personal car, another one happened about 3 months ago at the new branch. Story for that one is i had a car i was working on a 1.6 leon, I had just put a cambelt kit on (all pulleys and tensioner) the car for some reason went to snows for a mil light on. They phoned the customer up saying the cars timing was out and needed new cambelt and pulleys as they needed changing!. Needless to say the customer phone me up having a moan so i said bring the car straight to me and i would take it to pieces while they waited to sproved what utter rubbish they had been told. They took this up and i duley stripped the car for them there and then showed them the new parts (fitted correctly!) and then checked the codes again for them. A p0420 code for cat being no good as it was a cheap **** non type approved one. Chuff all to do with the timing in the first place! Needless to say the customer wasnt very happy with snows and wont ever go back! new cat decent type approved one and away they went. STEER CLEAR!
