How to troubleshoot a flashing check engine light on an Audi 80?

I have a 2002 Audi 80 and the check engine light keeps flashing. Can someone please provide some guidance on how to troubleshoot this issue and potentially fix it?

The first step is to retrieve the error codes using an OBD II scanner. This will give you a starting point for troubleshooting the issue. Additionally, make sure to check the gas cap as a loose or faulty cap can sometimes cause the check engine light to flash.

If the error code indicates a misfire, start by checking the spark plugs and ignition coils. These are common culprits for causing a flashing check engine light. It's also a good idea to check the timing belt and fuel injectors.

In some cases, a failing oxygen sensor can cause the check engine light to flash. Check the sensor and replace if needed. It's also important to regularly maintain your Audi 80 to prevent any potential issues.
