Engine Performance problem
2003 Volkswagen Passat 4 cyl Two Wheel Drive Manual 122000 miles
My car throws out black smoke when accelerating. It seems to be significantly doiwn in MPG also and there seems to be s light loss of power. Turbo does not seem to be packing the punches. Have had the diagnostics run on it and the only thing that showed up was the "Coolant Temp Sensor". Have replaced this and no better. Have changed where I get my fuel - no better. Have added an engine cleaner to the fuel - no better. Also have another problem which is while accelerating the car vibrateds like mad and it comes up through the gear stick. Have diagnosed this to be the Dual Mass Fly Wheel. A problem I could do without. But the black smoke is really annoying me. Any ideas? Have read in otehr forums that the EGR valve gives trouble but should this not show a fault code on the diagnostics equipment? Any ideas? All suggestions welcome!
