When i picked up my s3 a few weeks ago i knew it would need a bit of work. ive sorted most of the problems but one remains.
The boost seems to be a bit intermittent.
so far i have checked for boost leaks. i found that there were leaks in a few breather pipes and also a small leak in the turbo intake pipe.
I replaced all the offending pipes with nice new silicone ones at the weekend but there till seems to be random hesitance when i put the foot down. sometimes it pulls like a train and other times it stutters and then boosts.
When i was replacing the TIP, i did notice a slight bit of play in the turbo left to right.
Ive also been doing a bit of reading about the N75 valve so this evening i unplugged it and went for a spin.
I have to say, the car felt like it had only 120hp but it was absolutely smooth all through every gear.
does this mean the valve is good or bad
ANy help on what to do next would be much appreciated
cheers
