Reliability after 115k miles

So far, I've replaced my fuel pump/fuel filter

Coolant flush

Belts and 1 of the pulleys (alternator or idler I think)

Control arms replaced when I bought car

About to replace clutch/flywheel/trans fluid this weekend

Any other areas I need to bring to my attention besides spark plugs? (I will be doing them within the next month or so)

Why replace just one pulley? See sig for more info. Do coil boots, clean ICB, TB, MAF, DISA. Reseal all. Replace all fluids. Change O2s, change CCV system (cause for vacuum leaks due to cracking/drying with age) and needs to be done at around 100k miles. Vanos seals shoud be done too.

Lol only replaced the one pulley cuz the bearing in it seized last winter. I checked all the other pulleys when I was in there and the rest seemed fine. But good point I will probably replace the rest when im not lazy lol.

But could you explain what the ICB TB and DISA are? Sorry bad with acronyms :/

And on the vanos, I had a BMW tech tell me that on non m's, the vanos is self adjusting so there is no reason to mess with it. To me, this doesnt sound correct, Maybe he doesnt know what the hell he's talking about.

Thanks

I'm at 204K here on my 00 328Ci and it's still running like clockwork.
I drive it 120+ miles a day, every day.
