Need pressure switch for Hydraulic booster 443 919 081

[Ben Swann]

I need replacement 443 919 081 - can be new or used/good condition.  This is factory
pressure switch on '90 Coupe Quattro and others.

Mine blew open expelling Pentosin Fog 007 Oil Screen on BMW that was tailing me in my S2
CQ!  Surprise =0 unentended secret weapon!.  I lost brake boost and power steering -
hope I didn't ruin the pump.  Presently substituting one from Ur Quattro Brake Bomb
assembly, but would like the correct  one installed.

443 919 081 - mine has suffix C.  This is 107 Bar pressure switch mounted on the
hydraulic booster from various turbo quattros and coupe quattro.
