I have a few of those here from my e30's I'll throw one on when I do the cooling system refresh.

Installed an O2 sensor

Bank 2 upstream. Runs even smoother now! Maybe I'll even get a little better mileage too.

Replaced all 4 of mine a little while ago. No change in mileage for me.

Where did you find the fuel adaptations reset? I couldn't find it so I reset ALL adaptations. No change.

Got it on a lift at my buddies shop.
Got to see progress of the E39 M5 wagon he's building. I can't wait. Engine is out of the donor M5 and the touring is gutted. They're currently trying to figure out if they can use the touring harness, or if a harness transplant will be necessary.

Anyway. X5 shows no sign of coolant at the back, around he bell housing, and no sign of leaks from the weep hole by the pump. So all things point to the expansion tank. I'm telling myself I spotted residue on the tank. But my boy isn't so sure.
I'm home for a few weeks before I deploy, so I'm gonna monitor it and see if it goes away. A part of me really wants to just replace the damn thing, but I hate throwing money at shit that doesn't need it.

Put UV dye in it and get a black light flashlight. That's how I found my leaks.
