N55 = N54 only with a single twin scroll Turbo and modified software. Uses same crappy pumps and even a few people with N55 are also having waste-gates rattle just like they do on N54s. I got warranty on fuel pump extended to 100K miles by BMW proactively. And Yes, me like most other folks have had a failure. I'd much rather prefer they fix the issue once and for all rather than a guarantee via warranty to fix failures for free.
