Our BMW 220d xtrail 2014 is lighting up like a Christmas tree on every journey with various faults pinging on screen. We have been to the local garage numerous times but there are no faults. 

Sometimes the faults disappear during the journey on their own or vanish when you turn the engine off then on again. Same 3 faults each time as well.

Before we take it into a dealership we thought it would be useful to ask if anyone else has had similar problems & what it was.

On screen it comes up with the following faults:-

1) Front end collision warning restricted

2) Parking brake only partially working

3) Driving stabilisation fault

Fingers crossed.

Morning ! 
firstly, check the battery. 
amazing what a dead cell or discharging battery will do. 
the fact that they sometimes go away while driving could be that the battery gets enough charge from the alternator that journey, but loses charge next time you fire it up.
