Welcome to the board Desmond.

The soft close function can be a PITA if it's not working properly. On occasion when I pop the gate with the remote or from the drivers seat and I don't lift the gate right away the self close activates and tries to close the gate again - but unsuccessfully. It then goes into a cycle of repeated attempts until the battery drains. I found this out when I parked the X5 at the airport and came back to a dead battery. I must have accidentally pressed the remote gate release while jostling with the luggage.

Retrofitting should work if you replace the lower gate. There may be some wiring issues though.
