RE: N75 valve?
The N75 is the wategate valve. So it controls boost. If it's starting to go bad, your boost will be all over the place, or just low/high. Sometimes it will not throw a cel, but there might be a stored code.
It's under the passenger side plastic cover. It's just a valve with one electrical connection, & 3 vacuum lines coming off of it.
If your car is not making full boost, scan it for codes, do a quick 115 log with Vag-com, if that checks out, clean the MAF & check your DV's.
