I understand. My N54's all had a ton of issues. It was the faster motor (because of the two small turbos), but it was also the more problematic motor. The N55 is much more reliable from what I can see. This is part of why I traded the 08 535i for the 11. The 08 had quite a few issues and I was getting tired of dealing with it.
