Cheers Byzan It's going to an independent tomorrow we'll see what they say. Is that the way it works though - if the diag says it's wrong no one even actually tests what gasses are coming out?

Not in the UK no, In the US they check for OBD2 complience and readiness. But not here

Take it somewhere else as that code can be thrown with a faulty o2 sender too. The other code is more likely a faulty secodary air injection pump, won't affect the running as such, but may throw you into limp mode occasionalliy

hhmmm - so that sounds like Tetbury Audi (Gloucestershire) main dealer failing my MOT when they shouldn't and trying to charge me £950 for a pass. Guess that'll cover their loss leader 'free MOT' offer. If that does turn out to be the case I'll be asking them why they think it's ok to do that. Thanks for the advice. I'll post back here with more info when I get it.
