Nice thread pull-up! Happy New Years to all you N54 sucka's ... may the field of dreams continue to deliver on the fantasy of reliable BMW turbo power. May your diagnostic equipment continue to baffle you on top of your engine codes baffling you on top of your BMW's baffling you. May the parts continue to pile up in your basements and garage, as you push push push to get them on your cars, only inhibited by the ability to diagnose both persistent and new issues as you bolt on. May your tuning continue, but more importantly, may your dyno pulls continue to show progress with the, I-woulda-pulled-more-but-I-had-XXXX-code ...... . Learn from me boys - sell your house. Mothball your N54 car in deep car storage, all your parts buttoned up in a steel container deep in climate control, drive your diesel BMW like an old man and, when you want to have some mechanical fun, work on your old 7.3 Powerstroke with roll-up windows, which can be Neanderthal'd with pleasure.
Happy New Years!
