Did you have white smoke out of the tailpipes? Engine light on the dash? My 09 has 81k and doesn't seem to show any signs or oil usage. If something is going to go wrong, I hope it does it soon because I've only got five months of CPO left.

This has been a problem with the N62 going back to 2002 E65s. There's a company in California (All German Auto) that has made a pretty cool kit as an alternative to pulling the engine and the cams...although the kit is pricey at $800!
