Well, I took out the A8 steering control module which would not communicate with my control unit but did allow my heated steering wheel to work, and re-installed the steering control module originally installed in my A6 which does communicate with my unit although won't accept coding for the HSW. I am wondering why the A8 module doesn't communicate with my unit. Could it be a matter of coding? It would seem all the modules must, at least, communicate with the as all cars have that as std. equip. There is security for Steering but I don't know where to find it and doesn't provide it as it does for . If this information is not available I'm just going to bite the bullet and get the module ETKA says is proper for A6 w/ HSW as per gupster's last comments.
Thanks for the help.
