Thanks to everybody. In the event, I was being thick and forgot that on Windows Vista you have to run the program as administrator. I have now downloaded Alfadiag and playing about with it......But there is always another question. This time relating to ECU number. I found an old post from 11-04-2009 and posted by Duncan 2047, but still not sure what the final agreement was, as it got a bit acrimonious. Anyway a 2002 147 2.0 TS Selespeed - which ECU? According to Alfa diag table it's a ME7.3.1 for a 147 2.0 TS (no mention of selespeed though). Only specific mention of selespeed is for 156 2.0 TS and that is ME3.1. Yes, I know this is the same whole question all over again - but as it's nearly 2 years down the road I'm hoping it's been resolved and tempers have cooled off.
Another question is does anybody have any pointers re rear screen washer/wiper. Mine dispenses the washer fluid ok but refuses to wipe. I have checked the fuse, and that is ok.
Any help appreciated as usual. You are a great source of help. Don't forget I'm an old man and dogsh*t at computers and technology. I'm still a mean dude with a spanner though.
