What is the cause of the flashing check engine light in my Audi A2 and how can I fix it?

My Audi A2's check engine light started flashing while driving on the highway. After pulling over and checking the manual, the light has turned off but I'm still worried about potential issues. Can anyone advise on what the cause might have been and what steps I can take to fix it?

The most common reason for a flashing check engine light in an Audi A2 is a misfire in the engine. This can be caused by a faulty spark plug, ignition coil, or fuel injector. It's important to get your car checked by a mechanic as soon as possible to prevent any further damage. Also, make sure to use high-quality fuel to avoid potential issues with the fuel system.
