Are you able to set the basic settings on the throttle body with your scan tool ?
Customer: replied 1 year ago.
No
Expert:  Audi0405 replied 1 year ago.
Ok you will need to try to get access to a vw capable scan tool to see if you can see if you can set basic settings on the throttle body to rule that issue out especially since the battery was unplugged for a decent amount of time .
