Audi Oxygen Sensors and Spark Plugs

It is recommended to replace Audi spark plugs after 40k miles.

Do not use generic/standard o2 sensors. At least generic Bosch (no connector). OEM Bosch with connectors is even better. Generic/Standard oxygen sensors will never work on an Audi due to their signal constantly changing. There is absolutely no way around this. You either buy Bosch and Check Engine light goes away, or you spend money on generic sensors, crimp on connectors, labor to replace them, only to find that the error code does not go away.
