Well last Thursday the car arrived on a flatbed truck from Topeka, KS having been repaired. The issue was the ignition coils. This problem plagued many earlier Audi/VW cars but not the A8L. With only 5 miles on the car sense repair the check engine light came on again. This is a rather concerning issue. The Audi dealer in Omaha does not have time to look at the car till the later part of this week. After talking with him he thinks that it would be very rare to actually have something mechanically wrong with the car. Instead he thinks a wire was not fully pluged in or something jiggled loose. I will keep everyone updated with this situation as it progresses.
