Power-assist servo for t quattro coupes

[smarinel@Flint.Mines.Colorado.edu (Steve Marinello)]

The power-assist servo on my coupe has begun to leak seriously.  That
wonderful piece, Audi P/N 857612107A, goes for an list of $987.  Does
anyone know a source, possibly euro, that has it available for
significantly less.  The word is that it goes for about $300 in Britain.
SportWheels in Glenwood Springs,CO has a rebuild seal kit that they are
testing out, but that's all I can find.

Also, has anyone got any comments on the ECU "chip" upgrades available for
the turbo coupes?  ...particularly from Ivor at TAP (Total Audi
Performance) in Florida or Ned Ritchie at Intended Acceleration in
Washington.

Thanks,

Steve
