well ive heard the bypass valves they use on the 1.8t (bosch) lose diaphrams every so often.
audi drivers last issue discusses this.
they recommend instead of buying extra diaphragms to go buy a better bypass
valve, an adjustable one that uses o rings instead of the diaphragm plus it looks better (billet alluminum).
i doubt you can beat the one forge makes

now if this is whats wrong and you replace it and you want to get rid of the old
one... my 90tq doesnt have one at all...

thanks
