Headlight/electrical issues
 

I have 2011 mini cooper. Was driving down the road and headlight code on my dash came on and when signaled to turn I noticed the turn signal was twice as fast as normal. I got out to check the lights... the passenger side front blinker didn’t work, rear driver side blinker didn’t work, front low beam on passenger side one side marker on passenger side. They all stopped working at the same time. Checked and cleaned all the bulbs and fuses. Any other suggestions? Could it be the computer?
