Hi all,
For ages now I've had this problem and I want to fix it. The turbo rarely boosts unless I double-click the throttle - so I put my foot down, no boost, quickly release the throttle and replace my foot. That seems to kick it into life, until I change gear. Or perhaps there will be no boost in 2nd, then boost in 3rd, then no boost in 4th.
This seems to be temperature related - boost is always there when the engine is cold but by operating temp, the intermittent issue appears.
VAG-COM shows 17956 Open Circuit - Intermittent.
Measured the N75 unplugged and it shows approx 30 ohms (cold).
What should my next diagnostic step be? Should I replace the N75?
thx
Chris
