Hi all. I had the injector seals replaced and the inlet manifold cleaned a few weeks ago due to bad starting at times and mpg had dropped from 43 mpg to 37 mpg also a louder diesel noise under acceleration. My veccy has done about 500 miles since the jobs were done. Still a little bit bad to start but not as bad, coughs a little bit then a bit of smoke then runs ok (leak off pipes were done last year), mpg has gone up to 40.7, the louder diesel noise under acceleration is still there.
Does anyone have any other ideas what could be the problem.
Cheers for any advice. My veccy is a 2.0 dti 52 reg.
