Re: Bypass Valve help...
This is for a modified 5KTQ setup and the 0-280-142-102 (borsch number on
the current NEW valve) seems too weak. The spring doesn't seem strong
enough. When the throttle is decreased slowly while under boost
(1.3-1.8bar+) the car lurches as if the valve is completely dumping then
snapping shut again. The current valves have not worked by themselves (ie.
w/o the vacuum hose attached) The car will not make 1.2 bar as if the boost
is leaking by the valve. In that setup, the system should be sealed and
acting as if there is no bypass valve present. Seems that unless there is
boost present in the vacuum actuator line, the valve will not stay shut
under high boost situations. The current valve is brand new out of the box
and replaced a thought-to-be faulty valve of the same number.
Any ideas?

Go for the 034 145 710 N. This is what I have on my 96 S6 and it's also used
on all the 1.8T engines as well as Porsches.

I have been told by my Audi specialist that surging can occur if the
wastegate diaphragm is leaking. Is that any help?

Well, I would have too agree with that theory. When the valve is taken
completely out of the system, there is no surging during throttle decrease
under boost. There used to be an audible "stssssssssss" when the bypass
valve actuated, now there isn't.
I still need the part number for the Bosch Sport 110.
Or if anyone has a forged valve they want to sell....??

The Bosch 110 is exactly the same as the Audi 710N - also used in SAAB
