This is not entirly accurate: I tried a aftermarked cross-reference
Audi P/N 443 611 021 (23.8 mm) = HITEC BMC P/N H417150 (23.8 mm) which had
to replace the original BMC (and not the mentioned upgrade 5000 BMC) and
this still did not fit inside the servo. The outer diameter was too big.
Fortunately I got a refund and bought me the Audi BMC.


1986 GV (Swiss WR)
1985 CGT KV
1982 GL DD

This has recently been discussed at length on one of the UK web boards -
Maurits (who posts here too from time to time) has hit exactly the same
problem, the later master cylinder won't fit an early booster.
