O2 Sensos Bank 2 Downstream Location of Wiring
Hello, I have a 2017 S6. I need to change the after cat O2 sensor for Bank 2. The sensor is in plain view, but it looks like the wiring goes down the engine block to the bottom. Do I need to lift the car to get to the wiring?

Wiring does go down the block and I believe the connections are easier to access by removing the wheel and wheel well cover.

I hope you're aware that these O2 sensors are covered by a 10 year 120,000 mile extended warranty from Audi.
