The ECU pin listing and pin diagram was exactly what I was looking for while trying to troubleshoot my N249. Thank you for that Tony, I am glad to run into this forum which I just joined.
Question: According to Bently's repair manual and according to your ECU pin list, ECU pin #105 is for N249 connection to the ECU, when I checked my ECU's harness there is no wire in pin #105, that explains why there was no continuity between the N249 plug wire #2 and the ECU pin #105. It looked to me like this is how it is from the factory. Did Audi forget a wire? Has any one run into a similar issue? My S4 is a 2001 6-speed USA market. Please help to clarify this confusion.
Yes, I have the same issue, Pin 105 there is no wire, and N249 is no where to be found on the wiring diagram.
