Hi Guys, i have some issue with the reverse sensor after i replace a aftermarket bumper. it sounded like beep beep beeeeeeep beep beep beeeeeeeeeeeeep...2 beeps 1 long beep..not the usual beep when there is something behind is block..is a different beep much high pitch type...

Probably one of the sensors has failed. Try to check each one of the sensors.
Put in reverse mode (get someone to do it, and brake), go at the rear and if you put your ear close enough to the sensors, you should hear "tik tik" sound if it is good.

Easier way(if you own bmwscanner), plug in bmwscanner, you should see which sensor failed on pdc module
