How to properly maintain and service the catalytic converter in a Audi 80?

The catalytic converter is an important component of the exhaust system in a Audi 80, responsible for reducing harmful emissions. What steps should be taken to properly maintain and service the catalytic converter to ensure optimal performance and longevity?

Regularly check and replace the oxygen sensor to ensure the correct air-fuel ratio is maintained for efficient catalytic converter functioning. Also, periodically inspect and clean the converter to remove any build-up of contaminants.

Avoid using low-quality or contaminated fuel, as this can cause damage to the catalytic converter. Also, taking the car for a long drive on the highway every few weeks can help burn off any contaminants that may have built up in the converter.
