So here is a story of self inflicted misery that I hope someone might be able to help me put right. The weekend before last the engine light came on on my GF's 2001 156 sele SW. So I plugged in Alfadiag and cleared the error relating to the MAF no problem.
After I'd done that and having some time to mess around, I thought I'd have a look at the selespeed function of Alfadiag and see if I could make any necessary adjustments. I should add at this point that the car has been working perfectly and the selespeed in particular has never given the slightest problem.
I ran the clutch auto adjust calibration routine and the clutch bleed routine and all of a sudden the flashing red gearbox light of death showed up on the dash! So I ran the Auto calibration / EOL routine to try get everything back to normal and was rewarded with the sele unit evacuating the contents of it's reservoir onto the ground!
I quickly found the leak was comming from the passenger side of the actuator housing. A round metal disc with a seal held in place by an internal circlip had been pushed out if its housing and the sele oil was pouring out.
So I removed the selespeed unit from the car and had to source a replacement circlip and seal (as I've read on here parts are non existant and when I tried Alfa the poor parts guy nearly died of embarassment when he had to tell me the circlip wasn't available and a new Selespeed unit was 1800 euro!) A quick trip to a local engineering supply company sorted the replacements.
Everything was refitted having taken off the back plate of the unit and realigned the selector arm correctly etc.
Yesterday I reinstalled the Selespeed unit back into the car with new finger bolt and everything aligned properly and bled the system and when finished plugged Alfadiag in to run the auto adjustment / EOL. The routine wouldn't run and when I checked for fault codes it threw up the 1742 error. I ran the clutch bleed routine and the clutch auto adjust both of which completed.
I started the engine to see if i could select gear and was able to select 1st, Neutral and Reverse but that was all no 2nd. I changed the gear 3 or 4 times and then heard spraying! The same disk in the side of the actuator had been pushed out again and the sele oil was pouring out. The housing for the disc or the circlip is not damaged so I see no weakness that would just allow it to pop out.
At this stage I'm at a bit of a loss as to what's happening. Any ideas lads? I'm hoping I'm just doing something stupid that might be obvious to someone...
Thanks for the help and any kicks in the a*$e for messing with a perfectly functioning Selespeed will be more than deserved
