Audi A6 3.2 - Oxygen Sensor B2 S2 Replacement

The car reported that the rear oxygen sensor on the driver's side has failed a little more than 6 months ago. This single code 17530 (P1122) has triggered a CEL (Check Engine Light) on the instruments cluster which has been annoying me since. I have finally procured a replacement O2 sensor. This thing is actually very easy to replace. You just need to have the right tools. See how I proceed.
