F20 front pdc goes crazy

Hi all,
I have retrofitted front pdc to my bmw f20 from 2014. It works great when I'm trying to park the car in a spot. But when I fx stay on a road without any obstacles in front of me. Then the 2 front center sensors goes absolutely crazy like they were a wall in front of the car. I have tried to change the sensors with the outer ones to eliminate any non working sensors, but no different. The middle sensors still goes crazy. So no matter what I do, then the middle sensors keep continuing to beep. It's really annoying because I think that I've done everything like it said in the different guides and in bmw original retrofit installation manual. The sensors has been mounted on the originally marked locations inside the bumper. And my bumper is a non m bumper.

Is there any place to change the sensitivity? Or should the sensors be recalibrated? All the parts is by the way original/OEM.
