50k service
My car is currently almost at 50k I already plan on swapping out spark plugs and changing my oil, but would you guys recommend transmission fluid and differential fluid changed?

See this thread: https://f80.bimmerpost.com/forums/sh....php?t=1763835
I guess for now, just do the diff. Literally takes like 5 mins. Remember to take off the fill bolt first! |

DCT fluid does not need to be changed. I did mine at 77k and the fluid looked pretty clean. I also sent a sample to Blackstone and the oil still had plenty of life left. Generally you're concerned about how acidic the oil is at that age, but even that was good (TAN was low). I like to rely on the data rather than a label that says lifetime, but the data shows that this may be lifetime.
