just bought a golf 1.8t anniversary on a whim! I am used ti mk2 16v and g60 engines but know nothing about 1.8t engines the car has no history but has covered 102000 miles backed up by old mot's has a stage one remapp apparently on start up its runs fine no smoke etc but once up to temperature and under acceleration especially if you come of the acceleratior it smokes (I assume can't be doing the cat any good) I assume it's needs a turbo rebuild? today I checked the oil before start up and it's overfilled not by much though as I say I know nothing about turbo cars but with this car the turbo power seems erratic either on or off and at times seems to hold back? should I just track down a specialist with this engine and be prepared to have my wallet emptied!! anyone know one in Northern Ireland.
I used https://belfastservicecentre.co.uk/ when I was over a few years ago, extremely helpful / pragmatic re. my B5 S4. I have limited experience of this engine, our Mk4 GTI `blew` due to oil blockage / starvation ... much less miles and with a decent (on paper) service history.
