Hi New here
Just wondering My XF keeps draining the battery and I have no idea why, Everything is off and locked every time, Also just wondering about blue tooth as the head unit will sometimes find my phone and then it will not even find any phone nor have a list to choose from and then the screen goes into some sort of rebooting mode
Thank you for having a look Jason

 

You need a new battery will cause both your issues

 

Start with the battery. If that's replaced and fully charged and you still have an issue then the Bluetooth module under the passenger seat is failing. They can get wet and cause issues
