Yep, the problem is the random sensitivity of the 'sensor' .. mine came right again today for about half day ..then just decided to turn on lights in middle of the day ..we are approaching winter here so I think you're spot on in terms of shade / cloud etc just tripping the sensor .. I wonder if there's a way to adjust the sensitivity for seasons ...my $9.90 outdoor spotlights have that technology ... wonder if my $120k BMW does
nah ... would be asking too much .... perhaps they'll fix via software patch down the track as enough people bitch to the service desk ...
