: If that fails try shining a bright light at the sensor in the display - that should make it go bright - after which it may operate as it should. I do not have experience with this approach but someone on the E39 board said it worked for them
Thats what worked for me and so far, for around 4 other E39 owners. I have had to repeat the process once after 4 months or so.
Good luck and let us know if this works
