X3 Master Light switch

Has a similar problem on my wifes 06' X3. Only difference being radio would stay on but all interior and exterior lighting would cycle from dim to bright and back every 3 or 4 minutes. Brought vehicle to dealer and after several days of diagnostic work they called back to tell me they replaced master light switch. Since then, everything back to normal! Covered by CPO warranty though! Good luck to you!
