G1000

I have the same issue on my 340i (17 plate). It first started last winter occasionally. No problems during the summer, but now it is every time it rains or has rained, particularly if cold and dark. If I use high beam it works fine, but then I may start to get adaptive headlight failure warning (again as far as I can see the adaptive headlights still work). Would love to know if disconnecting the battery works. I figured a loose connection or that a rodent keeping itself warm in my engine bay has had one nibble too many on one of the wires. Cheers Gareth
