ive got a 2 probs with my 1.8T
1. the car idles fine and also drives ok but as soon as i hit just over 0.6 bar of boost the engine is really slugish like its farting as it tries to make more boost the prob gets worst like a missfire but i dont think it is.
2.also while im here i replaced my coolant sensor last month the 4pin black one but my gauge only seems to work when it wants to. is the gauge on a diffrent sensor. there is a blue sensor with 2 pins next to the black 4 pin one could this be it
Also i dont have any codes coming up on vag
