On the way home from work tonight I noticed my tfsi sport wasn't boosting correctly, if at all, and had a hissing noise from around 2500rpm. I'm still on the original OEM diverter valve so I'm guessing (and hoping) that's the issue. Is that what it sounds like?
I had a quick search, but couldn't see many posts with symptoms.
