Diverter Valve Failure - Audi B9 S4

Is your B9 S4, S5 or SQ5 experiencing a ton of compressor surge? It may be your recirculation valve failing. This has been a common issue across VW, Audi and related products over the years. There are always new revisions coming out and today I'm going to replace my diverter valve with a new one. I started getting horrible surging recently and traced it down to the original diverter valve which is an older revision than the most current. My car is right around 23,000 miles at the time of the video.

ProCharger Bypass Valve Sound

I shot a quick video of what the bypass valve sounds like on my 2016 Mustang GT. This puppy is supercharged with the ProCharger Stage 2 kit. This audio was a blend of a mic on the intake and a mic inside the car. This represents a lot of what it sounds like revving on the ground at a light.
