The latest part has been referred to as the -110 valve. Search
Audiworld for the exact Bosch and Audi part numbers, it has been
discussed extensively there.

IMHO, you should go for the Forge, Bailey or TurboXS valve if
you are running high boost and don't want to deal with failing valves
and/or leaking boost at high pressures. Expensive, yes, but cheaper
in the long run when you replace valves annually (or more) at $35/ea.

I wanted to know if anyone knows what the latest vag or bosch parts
numbers are for the turbo bypass valve. Has the current version been
improved, or is it the same design from the 200tq?

If there have been supercessions, I'd still like the old numbers, too.

Please reply privately as I'm not on the list for now.
