Hello everyone, I'm still pretty new to the BMW world. My car just past half way through the warranty period and I'm seeking some input for maybe a list of items to address or to closely monitor for the M2 (N55)? (In general but more focused on the power train) Looking at the forums and Youtube. I gathered the following:

1. Charge pipe. (I recently addressed by installed FTP CP)
2. Gunk build up on intake valves. (I addressed by installing a OCC, although it haven't caught anything lol)
3. Oil pan gasket, valve cover gasket, and oil filter housing gasket. (I been closely monitoring these. My oil pan gasket was seeping a bit at 10k KM, going to have it replaced under warranty this week)
4. Crank hub. (Seems like it is more likely on the S55 as everyone knows, have anyone here upgraded their N55 crank hub? I couldn't find an example, I'm likely just going to chill with it and hope it is very rare especially on the N55)
5. Tail light condensation. (This I found out on my own car when I noticed both tail lights developed hair line cracks. I got both lights replaced this year)
6. Head light condensation. (Not as common from what I seen, will closely monitor)

Personally, I'd had some bad luck with my 2018 M2. In 2 years I've replaced: rear caliper/rotor (driver side rear caliper was seized from factory), replaced head unit (Infotainment system would glitch and start navigating by itself, making phone calls and etc if my iPhone was connected), both rear tail lights mentioned above, and now most recently will be replacing the oil pan gasket. I still love the car, but being half way through the warranty, I want to get a better sense of things to look out for before my warranty runs out and things to keep on top of after warranty. Thanks for the input in advance!

coolant hose https://f30.bimmerpost.com/forums/sh....php?t=1547622

water pump should also be done somewhere between 50k-100k

I'm doing the coolant flange later this week so I will make a diy since I haven't seen it done on an F series n55. It is not going to be easy since the solid oil cooler lines are in the way but I have an idea how to reach those bolts, and I have an idea on how to remove the plastic flange without cutting the metal ring and potentially damaging the hose.

Good list, but remove the crank hub, no such failure in an M2.

Hmm, I had more issues with my Honda, back when I was in college.

Looking forward to this!

I can't wait to diy it lol.


There will be no torque specs in this diy because you cannot fit a torque wrench or any sockets in the area. Also because ista has zero info for this part.
