B139700 hvac faulr


Recommended Posts

Hi guys, got a mk8 with the above fault. It was in a smash but all error codes cleared new seatbelts etc so no airbag light or anything. Now digital climate control is not working due to above fault. I am also getting fault code b109ef0. Does anybody know the standard coding for the hvac fault so I can overwrite with vcds? Any help would be appreciated
