Hi All, I will try to be really short... I have a 54 Reg A4 2.0Tdi 140 (B7), 96K miles. Symptoms: 1- No power at low RPM (nothing until 1900 rpm), nowhere near what a 140 should be like 2- loads of black smoke (I mean LOADS) under hard acceleration; not so much when accelerating slowly 3- idling at 950rpm, is it normal? 4- when stationary, along with the usual diesel noise, there is a non regular tapping noise coming from around the alternator; any idea? 5- Combined MPG is....34MPG.... Recent VAG com check showed: 1- EGR overboost 2- 2x glowplug issue The garage doesn't know what to do (has been 6 month that they do not know...) I thought about a sticky vane turbo situation and looked at Innotec but I did not want to go ahead without second opinion. Any idea? Thx for your help guys.
