Z4M post-cat O2 sensors: wide or narrow band?
Does anyone know definitively if our post-cat O2 sensors are narrow-band?

Narrowbands have 4 or less wires.
https://www.bimmerworld.com/Exhaust/...1-406-621.html Widebands have 5 or more wires. https://www.bimmerworld.com/Exhaust/...787540167.html Pre-cat are wideband, post-cat are narrowband.
