[Barefoot-335is]

So my 2012 E92 335is coupe started to have a weird issue this week. I usually keep my headlight switch on "A"/Automatic and in the evening when I go to leave the lights and dash lights will come on, go off, come on, go off quickly and repeatedly. If I turn the Headlight Switch to ON and Not Automatic, the headlights and dash lights work perfectly.
My question is "Is this a Headlight Switch issue, a FRM/Footwell Module Issue or what?"
Thanks for any help,
