I managed to find a local source for a proper check valve. The new
Bosch valve is quite similar to the one it's replacing--just a little
shorter in the mid-section, but there's plenty of room to install the
banjo fitting and also the damper. The reduced length in the middle
makes it a little more difficult to get a (box) wrench on the flats
of the valve to tighten it up, but it can be done.

The new valve is now in--we'll see if it cures the hot-start problem.
Considering that I could easily blow air (hot air, of course) through
the old valve I just removed, it seems certain that the new valve
will fix things.

The good Bosch p/n is 1 587 010 533 (cross-over from the Audi 443 906 093)

P.S. The Bosch p/n to *avoid* is 1 587 010 004
