Our 2000 A8L loses power when turning left. The engine doesn't shut off, but it loses power for about 5-10 seconds. It also triggers the ABS and Brake lights. It used to only happen when turning left and hitting a bump, but now it happens frequently and sometimes in just a mild turn. I think that I understand the potential problem that may be causing the ABS light (ABS sensor or ABS harness short), but why would it be associated with a loss of power? Any ideas would be greatly appreciated.
