Hi everybody Had the vehice back in yesterday told the customer that the fault would probably be turbo. Told him that the turbo would cost him £700+VAT, he said he wasnt going to bother and sell the car. As he was turning round in the car park the engine had a real bad diesel knock, i heard it before but there was no knock control faults stored. I was just wondering if it could be the injectors causing the fault, even though there is no fault codes for the injectors. I took the codes of the injectors and tried to code them in but still it had a diesel knock. Any help would be most appreciated.
