So I have had my OG MY2017 M2 since birth.

Just reached 50,000 miles and I have loved every mile.

I have done regular oil changes, brake fluid flushes and been through a stupid amount of tyres as I track the car quite regularly, and I don't usually hang about on the road either!

Car is bootmod3 Stage 2.

So the car been used in anger quite regularly.

Car is going in for engine oil, DCT transmission fluid, spark plugs and horn replacement, being done by a good friend who also happens to be an independent BMW specialist.

Is there anything else I should consider? Any suspension items that I might look at replacing? What would you replace?

Thanks

Diff oil (oem MSP/A part # 83222365988), specs say to replace both fill/drain plugs (# 33117525064), they have a rubber o-ring seal.

The hose connecting coolant expansion tank to top radiator hose - the plastic hose connection is known to fail at the radiator end (reportedly 70-80K km onwards) and when it does car has to be towed. It's a relatively cheap part and an easy swap with a cold engine. Did mine at 70K km and it was still strong (some break during removal) but still peace of mind knowing it won't fail at some remote location.

Do you know the part #?

If you remove wheels as frequently as it sounds, I would replace the wheel lug bolts or replace them with studs.

Taking notes for the future. Seems this is what you seek:

which is used on quite some number of 1, 2, 3 and 4-series cars.

A little Googling exposes some pics of what might happen w/o replacement.

Approached close to those numbers as well, looking forward to adding this coolant line to my to do list >.>

I wonder if the S55 has the same issue?
