Default O2 Sensor
Reset my engine faults and thankfully it wasn’t my cat converter that was bad. It’s showing o2 sensor. Where is the location of the sensor on a 2005 Audi A8 4.2 V8 Base

I believe Bank 2 is the driver's side, Sensor one is the pre-catalytic converter sensor.

Would this be the correct part or B2 S1?

I have no idea since there's no part number but it is Bosch which is the correct manufacturer. It's also out of stock and too expensive. As far as the OEM O2 sensors on your car, they're Bosch and I would recommend buying either the AUDI-branded version if you like paying too much or the Bosch ones which are precisely the same part. This is what you need:
