My Audi A6 C7 has no power to the MMI screen. What I’ve checked so far is as follows: 1. 1. fuse. Ok 2. Done the reset. 3. Opened the dash board checked the blue/red and brown power connector, no power. 3. Peeled back the soft cable cover to the screen to check wires for damage. The red/blue had slight damage. Cut and soldered, still no power. Now I’m really in a pickle. The radio, media, Bluetooth all work fine. It is just not getting power to light up the screen. Any ideas?
