Hello guys i am new to this forum please be gentle!
I have a 2005 A3 TDI 2.0 BKD SLine quattro.
I have just changed the dashboard and fitted RNSE and new (well remove from good donor car) steering angle sensor, steering ecu and cruse control stalk.
I now have ESP light, Airbag light and yellow steering light on constant, steering is now very heavy.
I have tried Ross techs calibration procedure with no joy and i have drove it apx 10 miles and its still the same.
I have tried diagnose with vag com 409.1, lite and 311 all fail to get connection with controller and state "no responce from controller".
I have both ross tech lead and usb lead and i cannot connect with eather.
This is strange as i can diagnose and erase any engine faults.
I am alittle stuck to say the least to how i can go forward with this so any help would be great.
