I have a 03 Audi 3.0

- I need to replace the O2 sensor

There are 4x O2 Sensor's on the 3.0L

When inspecting, the two that you can easily see behind the heads are the rear sensors and they're not hard to change, the front two sensors are not even visible without a mirror as they are tucked under the rear of the heads. The forward two most visible in this pic are most difficult to change with engine in.

Consider replacing high mileage front O2's if 3.0L is pulled, otherwise it's several hours per front O2.
