I have had my 147 selespeed for 18 months now and am still having some really annoying problems that Alfa seem totally unable to solve.
I have in the past had numerous selespeed failure warnings (now gone since new gearbox), not being able to engage reverse gear, refusing to change gear at speed, stalling in gear (all now in the past hopefully), and the final niggle - my car sometimes gets stuck in gear after being parked. The hydraulic pump does not activate when you open the door. It does this a few times for a few days and usually starts after 20 minutes of frustration opening door, bonnet, (and slamming!) turn on/off ingnition, etc. When it goes to Alfa to look at it of course it behaves beautifully!
So far they have:
Changed foot brake pedal switch
Fitted a new gearbox
Changed some wiring loom
Changed the hydraulic pump (this fixed it for 3 months)
Changed a gear change locking bolt/pin a few weeks ago which I thought was a waste of time.
Sure enough the problem started again yesterday.
My frustration is the hit and miss attempts to fix this. The diagnostics say nothing is wrong.
All that is left is to change the computer, which is what I suspect has been the problem all along (or is it software?), but this is so intermittent it goes weeks and even months problem free and then when you are in a hurry it just won't start!
What is the sequence that starts the hydraulic pump? The Alfa people here seem to have no idea, and their idea of troubleshooting seems to consist of changing out expensive parts until the problem goes away. Fortunately I am still with warrenty, but that does not help when the car just lets you down.
Is there maybe a selespeed software upgrade that the people in South Africa know nothing about?
I too bought the selespeed because I broke may left ankle very badly in a motobike accident many years ago and find pressing a clutch pedal painfull at times.
