Good day all. I have a 2009 A4 B8. The car will no crank no start. When I insert the fob nothing comes on but the e brake light. If I open the door the screen will say please remove key. The radio turns on but no sound. No brake lights, no interior lights, no wipers, no headlights, no horn, no power windows, I do have parking lights, lights on the doors work, power locks work, I have checked the floor boards no water from the sunroof, battery is good. The key will push in and release. I have pulled out every fuse and checked them bought new relays and swapped just to check if one was bad. Nothing please help before I blow it up lol.
