Help PROBLEMS Juddering 2.0 TDi 170
Hello there I have an audi a4 avant 2.0TDi 170 and I am having a few problems
I have read hundreds of threads on the internet about 170s and problems and I hope you can help me with my latest one.
The problem is the car will not accelerate when put foot down in all gears the car just judders like mad and takes ages to drive, this happens in all gears but will accelerate v slowly if just hold foot at about quarter throttle.
If I am above 2000 revs in all gears then put foot down hard the car wont judder but just feels like is not boosting and accelerates like a non turbo.
This only happens when car is warm if car is cold for first couple mins only of the drive, the car will fly like a 170 should but goes straight back to the symptoms after about 3 mins driving.
The car has had
new turbo - last year
new egr - last year
vacuum unit on inlet
cleaned egr numerous times
couple fuel filters - with no signs of oil in the filter
checked Vac pipe lines
The car has been in garage all week for latest set of injectors which i will be beginning my fight with Audi uk tomorrow to get money back, and the garage don't have a clue for the problem. On VCDS (VagCom) it shows up nothing all values on measuring blocks are correct even when driven and there are no fault codes so I have no idea what is going on please can you help ?
