JimsaudiA8L

I have a 2005 Audi A8L Quattro. the other day while I was driving, the door locks unlocked and locked on their own and the windshield wiper (which was set to intermittent) operated once. A minute later the doors unlocked and locked again. A few minutes later while stopped with the car in drive but at a standstill, the parking brake warning light (a "P" with a red line) went on. The parking brake was not on, but I set the brake and unset it just to see what would happen. The warning light stayed on just as before. The power steering also seemed to be slightly lacking while at the standstill, but was ok when driving. I arrived at a destination and the car was parked/of for a couple of hours. While driving home later the car operated as normal. This morning, the control panel by the rear view mirror is completely out - the homelink buttons and lights in the panel are totally inoperative. It would seem like a fuse issue, but do you have any suggestions about what is happening? Thanks
