Audi A4 2.0 TDi 2005 - Cruise control unit doesn't work #Archived Message

Had a quick look at this last thing tonight. No fault codes stored anywhere but cruise control refuses to work. Checking live data, the data referring to cruise control operation isn't very easy to decipher, but it looks as though there is a signal from the switch. Brake lights are working ok but I can see no data reporting clutch pedal position (if it even has any)
Using VAG com, I noted that in coding II, it lists a code to activate and deactivate cruise control, but this doesn't seem to do much. ECU software coding is 000072 and equipment coding is listed as 86425. Not sure what this is though....
