DV's going bad
What are the signs of diverter valves going bad. I read about them a lot, but not sure what the symptoms are.
I'm not having any problems at all, but with 62K on the car I want to know what I should look for. Did all the plugs and coil packs at 60K.

There's definitely no honking, and the tires try to break loose under hard acceleration in 2nd, so power seems good.
But was considering a silicone hose kit. I'll replace the DVs while I'm doing that.

As posted above 710s from VW/Audi work well. They're a little more money but the Forge Motorsport 007 or new 008 valves are also an excellent choice.
If they are bad you will have a boost leak. To test hook up a Mityvac hand pump and pull vacuum on them they should open and hold vacuum when applied to the vacuum hose fitting on the top.

As posted already you will know with the Geese-Honking sound AND reduction of boost.
I recommend that you pick up a set of 710N's.. They are now made by Kaiser. The failure rate on these valves compared to the stock valves is almost a non issue.
I sell them for $68.00 a valve..

Replaced mine at 60 w 710n. Installed Not too long after tune-up, so I can't say that I felt any difference b/f or after, but now I know exactly what I've got in there.

On my tt audis you could tell in turbo lag when they start to go. I upgraded to forge dvs when I was concerned. Honestly even though I have 10K miles thought about just doing it now.
