F10 BMW M5 Primary Oxygen Sensor Replacement DIY

Doing some maintenance work on the m5 by replacing the o2 sensors so the baby can monitor the AFR properly

I *think* white means just moisture or lean. Or normal. Sooty or black means rich. I *think* tho, not sure. If the o2 is self heating kinda changes it I think. I would read the plugs instead.

Nice! Double check how the tune looks after new 02 sensors
