Hi , Went round to Aspen's (btw he is a top lad) yard tonight as he agreed to help me change coding for Controller 09 Cent. Elec & 46 Central Conv. but unfortunately the vcds didn't read both controller giving an error for controller 09 can't read the controller for this ecu (cant remember the exact words) & for controller 46 not available.We used both 805.4 & Beta 907.0 to change the coding but no luck. We then connected the hex-can to Aspen's S3 and it worked perfectly fine on his car. Aspen suggested we wait for an upgrade by ross-tech and then try again as he believes my A3 is newer than his S3 and audi might have made some changes. Any kind of input regarding the above matter would be appreciated. Thanks Sal p.s His S3 is fabulous !!!
