Pre Sense Light

[Scott Petrie]

Hi
My pre sense light flashed on the other morning when i started up the car but went off again. Is this normal? Im reversed pretty close to my garage door and the house wall, could it just be picking this up or does it only work from the front? Maybe dirt on the sensors? Where abouts are they so I can check?
Cheers

Mines done that since I got it, spoke to salesman he’s says they all seem to do that, mine usually clears after driving off my driveway
