Please help me. My S2 '94 do the same. It goes nice a week or two and then it begin with the small jerk and then at the next acceleration i cutt at full speed. After that it cutt with about 0,4 bar. I know s2avantdk and his and mine car have exactly the samme fault.

Do a search on Hall sender .....sounds like your problem (both of you)

The Hall sender is changed on the '95 Without any change.

It's sounds like a boost leak and overboost protection but my betting is on the knock sensors, they need replacing.

Hall sensor wouldn't cause these sympthons, he would have problems starting and if it did fail during the engine running the ecu would still keep the engine running and use the crank sensor.
