I've done it too an a3 1.8t, so should be similar! There's quite a bit of work involved, and a fair few parts. You'll need a gearbox, clutch, flywheel, slave cylinder, clutch hyd' line, master cylinder, possibly a different pedal box or just a clutch pedal, gear shifter, gear knob and gaitor, different plastic trim around the shifter, possibly different driveshafts, possibly a new engine ecu + clocks + keys, sort the wiring out. I think thats about it! How keen are you now?? :-)
