88k is nothing for the Audi clutch, unless the owner does not have a clue how 
to drive a stick. My old '85 5000s just turned 235k in my friends hands and it 
is still on the original clutch. The 200 uses a robust Sachs-Boge clutch, so 
it's pretty forgiving. Mine also picks up pretty high. I don't like it but 
it's not adjustable. Replace the MC, slave and pressure hose first, betcha 
it'll cure it. Mine glides after that replacement (after two broken clutch 
pedals, I must admit. It was a sticking/clicking MC, that caused it).

A faulty knock sensor? Does not retard the timing so the brain cuts the fuel 
off? Pull the codes when it happens next time. At what boost does it happen?

Might be just the brushes. Take the regulator out and check the length. Oh, 
before that check the presence of the +12v exitation on the terminal 61 of the 
alternator (a blue 18AWG wire). It's jack (LF longitudinal member) likes to 
oxidise. No excitation -- no charge.

Disassemble the lever/switch and clean up. Use DeOxit (Craig).

No, it's in the switch itself.
