a4 1.9 td sounds like a bag of nails
Just came across this site where you all seem to know your stuff.
I have a 'w' a4 1.9td that has covered 150 thousand miles with ease,upto now that is, After a mot and basic service my car smokes first thing and sounds like a transit now. I will be honest with you. I work in transport for an electrical contractor and for the last three years have been mixing HV cooling oil with normal diesel,great... no probs smooth and clean engine great combo for years, till recentley when i have been using diesel out the yard then flat spots smoke and now the transit noise.
I have a clean reliable car which i want to keep but do i get engine restorer different oil or do i go to a diesel/injection mechanic??? I have tried new fuel filters injection cleaners etc
I'm at a loss need your help please :banghead::banghead:
