Bank 2 side???

About to replace a bad pre cat O2 sensor, the SES code is calling out bank 2.
Looking to confirm that is the drivers side?

Have you done an O2 sensor change on the E92 M3? Just FYI, you will want to unplug the electric connection for the sensor prior to unscrewing it. It will just make things easier since you dont care about the bad sensor and it will also prevent you from damaging the bracket the sensor plug fits in. It will also get everything open for plugging in the new sensor after you have screwed it in. If memory serves, taking out the rear 4 bolts and center bolt of the skid plate will give you enough room to access the connection points for the front O2 sensors. Just dont want you to make some of the same mistakes I did.
