"Open Circuit" fault on all doors

[Rlindorff]

Hey all. Just picked up a 2015 S3, in great condition. Only flaw - none of the door speakers are working. They are all throwing "Open Circuit" codes. Any ideas?

Hoping it is just a loose connection in the back of the MMI Unit, but hopes are only hopes.

Pull back the grommet in the doors, bet they are cracked. Play music also see if they work when you open the door.
