N55 reliability...
Just curious about the N55 reliability in the M2 so far.
Any known major issues? My mechanic told me of some older N55s seizing up (spun rod bearings). |

I doubt we'll know for a little while since there probably aren't too many past 75-100k, but every tech I've asked has said that they feel the N55 is among the more reliable modern BMW engines. Gotta factor in low sample size and subjectivity of the tech's, but that's what I've been told.
I think in the next few year's we'll start to see where it stands long term as the 16/17's start to rise in mileage.

However, isn't the N55 in the M2s the same as in the previous 3/4 models, just tuned differently? |

IIRC, it's more like a S55 block and bottom end with a N55 head.

It was just that my tech guy at BMW told me this morning he has now seen 3 N55 come in over the last 4 months due to seizing. Older models, 2011 and 2013 I believe... |

Ouch. Hopefully in 2022 mine will keep on trucking. If not, then hopefully an engine replacement will be affordable, lol!

I guess you could say that. I haven't seen anything disturbing about the S55 from the M3/M4 forums. The exact same S55 engine has been reliable in those cars since 2014. They have reduced the incidence of spun crank hub as well. Most of them happened to modded cars that have the DCT. Many of them had aggressive shifting software flashed on their DCTs as well as a tune. Now if you are talking about 10 years and 180k miles of wear and tear then yeah there are more hoses to replace. The N55 and S55 are both complex turbo engines and both have long term maintenance risks.
