Question about 2001 Volkswagen Jetta TDI
Full filter, air filter,injector nozzels are new. .189mm. It's smoking black & a lot. There is still no change in ml/gl. I bought a tird party OBD II cable with software that is supposed to work as a VAG-COM diagnostic tool. I scanned it, and it shows no codes. I still have not registered the tool, but i have tested it and it stops a lot of the smoke, but i can not save the changes. Am i going the right way to turn this engine more economical?
The catilic converter may be clogged. this could b.e the reason for the black smoke .it could also cause poor fuel mileage .you might try removing it and see if the black smoke stops .if it does change it and your fuel mileage should improve
