The auto learn is done with the wheel in the air and in drive mode. In parking mode it will only beep.
They send you a new controller?
It took me over three month with a lot of mails and video call sessions with the chinese until they said the first time they think about sending me a new one. Mine was equipped with the wrong firmware , 72V instead of 96V and I could not load the new firmware with a android tablet or phone, because the app was faulty. In the end I was able to load the new firmware with an I-Phone 6.
