Problem with retrofit High Beam Assist (HBA)

[vwseb]

Hi

I bought a used HBA mirror. I have modify Can wiring and coded the car.

Communication is ok. So HBA works but it looks not enough sensitive.
When I came across a car with good lights (xenon) it's ok but cars with lower lights, the HBA turn to low beam to late.
In both case, when car is far away, my BMW stay in high beam.
Same problem when I follow a car. I must be very close that my car go to low beam.

I don't know if it's a coding/parameters problem or if the mirror I bought is defectiv
