The most common cause of the Check Engine Light turning on in an Audi 80 is a faulty oxygen sensor. This sensor measures the oxygen levels in the exhaust and can trigger the light to turn on if not working properly. It is important to have this sensor replaced to ensure your engine is functioning at its best.
