No errors messages are displayed
I first thought perhaps there was some dirt covering the camera on the windscreen but confirmed it was all clean
(My assumption is that these are the sole sensors used by this system and not the radar detector under the front bumper use by the cruise control component)
This has occurred on the last few journeys so a restart of the car has not resolved this.
This sounds like a visit to the dealership and as it's out of warranty probably not a cheap fix but wondering if anyone has encountered this issue?
