BMW X5 E70 Boot Opening Porblem and Rear Sensors

[zbet1974]

Hi Guys,




Any suggestions:




* My rear sensors stopped working (front are fine), I have replaced the PDC module and the sensors but still nothing

* The remote button for my boot to open sometimes works if im close to the car and from below my waist. Is there a sensor that I can look at?




Thanks in advance.

Car: BMW x5 e70 2007 3.0D
