need help guys

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

cheers

craig


Also i dont have any codes coming up on vag

Squishy inlet pipe collapsing under boost?

 

[billybravo]

i think it could be my mass air flow meter does anyone have a write up on how to clean them

i had the same problem. is it fine if you dont put your foot down and let it build up? does it just happen when you floor it or even just a bit? mine done this like i was kangarooing the car lol and it ended up it was the N75 valve. could be this?

 

[billybravo]

cheers i will have alook i did check it on vag and i could hear it working ok but i will swap it for one out of my mates see if that works

Does sound like a dodgy plug to me, had the same problem, different car and it was the plugs.
