I seem to be lacking some boost on my wifes 2004 1.8t Avant
It’s kinda weird as although I think it is down on power its still not slow.
There are no fault codes and no leaks as I had a smoke test done on the system.
My thoughts were a N75 or Diverter Valve.
Both are stock units atm and the car runs stock. I don’t have access to boost gauge so unsure what psi it is running.
Couple of questions:
Would a fault in one of this cause a fault code?
If I replace the N75 , which part number do I need?
Any other suggestions would be appreciated as to the issue.
