Time for me to start thinking about 100K service on my 2011 X3 35i M-Sport. I purchased it used, non-CPO, and I have no info on what maintenance was done before I bought it and after the included maintenance ran out, so about a 2 year gap from when I bought it a year ago. The only major maintenance done since I bought it:
- New rear brake pads and rotors
- Oil filter housing gasket & serpentine belt

What I am considering:
- Oil change and filter
- spark plugs (OEM or is there a better alternative?)
- coils
- Water pump
- Flush/fill brake fluid
- Flush/fill coolant
- Fuel filter
- O2 sensors
- Charcoal canister
- Flush/fill transfer case/diffs/trans

Am I missing anything? Or doing too much? No air filter as I am using K&N filter.

thanks
