Why is my Audi 80's check engine light is blinking?

I recently noticed that the check engine light on my Audi 80 is blinking. What could be causing this and how can I fix it?

First, it's important to check the car's diagnostic codes to determine the specific issue. This can be done at a mechanic or by purchasing an OBD-II scanner. Then, refer to the car's manual or forums for troubleshooting tips or specific solutions for that code.

The most common cause of a blinking check engine light is a misfire in the engine, which could be caused by faulty spark plugs, ignition coils, or other components. Have a mechanic check the spark plugs and ignition system to pinpoint the issue.

The issue could also be caused by a loose or damaged gas cap. Check the gas cap and tighten or replace it if necessary.
