i think i'm in the same situation, read the following:
alfa 147 2.0 selespeed, ev0 changed last year.
i had been hearing a strange "rat rat rat rat"-like sound when cornering left at (roundabouts mainly).
a few days ago, the sound became clearly audible even in right turns. i was in fifth gear, city on, pressed the brake pedal, selespeed tryed to shift to forth, clutch did disengage (is it the right term?) but nothing, it was not able to do it, the N was flashing on the screen. The engine stayed on, the selespeed kept on trying to get in neutral. i turned the engine off, and it then refused to go on again.
next day i used FES and saw there was a "clutch sensor" error. drained the clutch, performed a EOL calibration-->failed (3rd and 4th position error)-->tried another time, success. Engine on, gears ok, but when i got to the fifth gear, exactly the same problem arose: same procedure, FES+Clutch drain+1 failed calibration+1 successful calibration. striaght to the mechanic. FES says clutch rod is 28.5 so just on the higher limit.
Pump and pressure values are ok.
when it gets stuck FES shows these values
My opinion is that the clutch bearing is gone, but it could well be that the ev1 and/or ev2 are gone...
i'm looking for a way to solve my dilemma...advice sought!
perhaps the fact that all gears work well except for the fifth could be a clue (for someone, not me).
