    N55's...how reliable?

    Hello people of SS. I just recently sold my N54 335i and was looking into the N55's due to so many issues that the N54's had. I N54's are known for wastegate rattle, vanos solenoids, cam ledge issues, HPFP, etc, etc...but I'm wondering how much more reliable and/or improved is the N55 engine...
