shortspoon, a bad brake light switch is know to cause the wing to deploy and the BAS/ESP warning light to turn on. The switch is located under the dash above the brake peddle. The brake light relay is located in the fuse box under the hood; You need to unsnap the upper tray with all the fuses up and get it out of the way to access the relays near the rear of the fuse box.
Have you tested all the wheel speed sensor circuits for 10 ~12v?? I hate seeing you toss parts at it trying to find the one which corrects your problem. Perhaps buying a good scan tool will save you money and time. You can get one that will do the job for about $200.00 or less.
