Ongoing sportronic problems
Is there anyone here that knows something about the sportronic gearboxes on a 166?
A friend's Alfa has dropped in to limp home mode running with 3rd gear only.
We have changed the oil (which was a little burnt) and that hasn't made much difference.
We have wired it up to some diagnostic kit and whilst running can reset the system so that it runs fine, however as soon as you turn the car off and then restart it drops back in to limp home mode.
If you drive the car and it warms up and then stop it for a short period of time (like filling with petrol), when you restart it doesn't go in to limp home and runs fine until the next time you start up.
On the dash we have what looks like the boot lid warning light on which the manual says is to do with the auto box overheating.
I get the impression that it may be a faulty sensor or dodgy wiring rather than anything mechanical.
Are there any sensors that I can easily get to to pull out and check?
Are there any workshop manuals for the gearbox around that can be downloaded?
Any help would be appreciated.
