a4 1.9 td sounds like a bag of nails

[lorryloader]

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

The HV oil is used , and put into 50 gallon drums for disposal, it is waste oil in fact for fear of being pursued by G Brown and it is a VERY common practice amongst those who work in HV cables so I am positive that isn't the problem, maybe my local garage failed in it's agreement with me to carry out all of the work to which he was being paid to

Can you be more specific? colour of smoke? does it clear, is it on idle or just on load? whats oil consumption like?
Power? does it feel low, Most probabily a MAF sensor as these are common faults

hmm, blue smoke indicates burning oil, could be your EGR valve blocked, or intake choked up with oil n ****.

Do a search on here for EGR valve cleaning and intake de-coke, lots of info out there, then remove ur intake and have a look, it's only 8 bolts.

These engines do coke up but depends how driven.
