Audi A4 Black smoke
I have an 2001 Audi A4 1.9TDI. It has been emitting puffs of black smoke through the exhaust. I took it to my mechanic who did this
changed oil changed oil filter changed air filter changed fuel filter this made little improvement but then the smoke came back. My mechanic then suggested me to try and use Fuel Injector cleaners and go for motorway journeys which I have been doing for the last 2-3 tanks with just little temporary improvement. (Used STP injector clear twice and Forte Injector cleaner once) PLEASE HELP ME AS THIS IS QUITE FRUSTRATING and I know if I take it to Audi they will rip me off as always. Thanks for your help |
