My understanding is that the wire being ran from PIN13 of the Steering ECU to PIN4 is the communication between the main Engine ECU and the Steering ECU. I would have thought that coding in the 11463 without that wire in place the 'G' wouldn't appear as the coding would be refused... though on the other hand the coding could be accepted without any problem and when the process for that coding is executed it then returns a fault, which is saved in the ECU log.
The latter seems silly as coming from a programming background it would be simple to incorporate a method whereby if a certain function is coded, the prerequisites for that function are looked up to see if they exist, and if not the coding is denied.
The simple way to test this would be to code in Cruise Control onto a vehicle without the wire and see if the 'G' pops up. I've actually got some work on a '04 A3 this Saturday which wont have the wire so I'll perform the coding then and let you know of my findings.
There are unfortunately no faults codes for the clutch switch. You can test whether it is the clutch switch at fault without costing you a penny... Locate the clutch switch and you'll see a plug with two wires going into it, using some wire, bridge these two wires together to bypass the clutch switch. If the Cruise Control now works you know it is the Clutch switch and you can order yourself a new one, they cost around £14 from Audi iirc.
