Hello all, I have a 1.9tdi 110 golf which I believe is a non pd ASV engine?
Basically, when I hit 3k revs in 4th and 5th (mainly) I lose boost and get limp mode. The turbo boosts really well when under 3k with no strange noises etc.
I have tried the usual, checked the boost solenoid, checks for vacuum leaks, ran fuel additives, even tried a mr muscle clean, but there hasnít even been a slight improvement, so is there anything else I should be looking at before I go and buy a new turbo? And are all turbos a direct fit? (Can I put a pd130 straight on)
Thanks in advance for any help!
