boost problems (n75)

Post by vdub mk1/mk3 »

Good day fellow dubbers

I have boosting issue on my car.

so the engine i have is a AGU 1.8T 20V and what i experince is quite strange, sometimes when the car goes into boost it give a violent jerk... when i put the diagnosing tool on it points to the N75 valve, so just want to find out if there other things that can cause this, the problem is intermited.

thanks in advanced

Usually MAF limit or Injector Limit causes that, is the car tuned via Unichip by any chance? What mods?

What was the exact dtc (P0****) when scanned?
Best way to fault find would be to log the car. You know anyone with vcds?
