The downstream oxygen sensor is screwed into a "bung" on the rear of the catalytic converter assembly beneath the vehicle. The sensor should be readily visible as it will have wiring connected to it. The sensor should not be removed...

This sounds like potentially a faulty idle air control module. This is a unit that regulates the flow of air into the engine. When this is faulty, it will result in an imbalanced air/fuel mixture which will cause the erratic...

Any car at 100,000 miles or more can have any number of issues come up. The things I list may not be exclusively A8 issues, but issues you can expect as more miles and time accumulate. Air suspension issues can...
