Engine Performance problem
2004 Audi A6 6 cyl All Wheel Drive Automatic 140000 miles
I have a 2004 Audi A6 Quatro with a faulty oxygen sensor. I would like to replace it myself and have a two part question. 1) Where is the HO2S Heater Control Circuit Bank 1 Sensor 1 located? Is it easily accessible?
