In this video, learn how to prevent EGR valve failure on a diesel Audi A4, which can occur due to short trip usage. Unfortunately, in these cases, the small radiator in front of the EGR valve becomes completely clogged with carbon deposits, preventing any airflow through the radiator.

This leads to valve failure, requiring a costly replacement (the valve alone costs about $240, not including labor). To prevent this issue, it is advisable to periodically clean the radiator of the valve, ensuring it can breathe and avoiding breakage.
