We just purchased a 2011 825i 2 weeks ago.
At time of purchase, the display worked perfectly, but windshield wiper and upper work lights were inoperable.
Found no power in upper panel of cab, and started tracing wiring back. Still have not found where this panel gets its power from, and now display panel doesn't work.
Sometimes, when you push horn button, display will flash on and off. When I push 4wd to "on", display lights up, but nothing will change, and stays lit up even with key off, until horn button is pushed.
Anyone have any ideas?
