Terrier Posted September 21, 2006 Report Share Posted September 21, 2006 This might be not a problem, but I just thought I'd check. I noticed last night that when I change gear on hard acceleration there's a dump valve sound. I thought my 1.8T Q has a divertor valve, so therefore no air release sound should be heard. Do this signify an air leak? It's quiet, so quiet in fact that it can only be heard with the radio off and all windows up. This might be the reason I've never heard it before. Am I worrying over nowt? Quote Link to comment Share on other sites More sharing options...
prt57 Posted September 21, 2006 Report Share Posted September 21, 2006 I have a GTI 1.8T with the atandard valve. When mine started doing it it was a sign that it needed changing. I have had 2 go over 7 years and they don't cost very much. Easy to fit yourself as well. prt57 Quote Link to comment Share on other sites More sharing options...
Terrier Posted September 21, 2006 Author Report Share Posted September 21, 2006 Cheers, I'll probably fit the improved type (with the metal pistion rather than the rubber diaphram) to get a longer life. Anyone recommend a good make/dealer? Quote Link to comment Share on other sites More sharing options...
S3ENVY Posted September 21, 2006 Report Share Posted September 21, 2006 If you're going down that route Forge are good, got one myself. There's also Turbo Dynamics which I think PaulS3 has, hyperboost and AmD do a "Viper" which I thnk might be the Turbo Dynamics in disguise.

Paul Posted September 21, 2006 Report Share Posted September 21, 2006 Mines a Amd Viper, which is a Turbo dynamics DV with the engraved AMD logo. Its the piston type. No issues over 40K miles, but i do have a above average service regime on it, but its obviously working. Quote Link to comment Share on other sites More sharing options...
DuncS3 Posted September 22, 2006 Report Share Posted September 22, 2006 I had the AMD valve which worked fine, but as Paul says it needs servicing and I could'nt be bothered with that, plus I didnt have a service kit from AMD either and then I noticed it was starting to stick a bit when changing gear so I went back to the OEM valve, which has never failed on my chipped car as yet.

Terrier Posted September 22, 2006 Author Report Share Posted September 22, 2006 Cheers for the advice. I think I'll stick with the OEM, £15 as opposed to £100 is a bit of a difference, especially after just changing the timing belt, tensioners, water pump, MAF sensor, coolant sensor, sencondary air pump, breather hoses, clutch pedal......
