After the A8L got the recall on BSG about 2 months, the CEL came on. So I waited to have the 60k miles service to get it done. I was the N509 needed to be replaced. I had the Oil replaced at the dealer instead of doing it myself. It cost $261. The air filter was dirty another $180, so I replaced it myself with $20 air filter at Amazon.
At Fremont Dealer, the 60k services cost between $1475-$2000 dependent on what you want to have done. Mostly inspections.
Replaced air cleaner:
