How can I fix the malfunctioning engine light on my Audi A2?

My engine light on my Audi A2 keeps turning on and off, and it's driving me crazy. How can I fix this issue without having to take it to the mechanic?

The most common reason for a malfunctioning engine light in an Audi A2 is a faulty oxygen sensor. You can try replacing this yourself, but it's best to have a professional handle it.

Another possible cause for a malfunctioning engine light is a loose gas cap. Make sure it's properly tightened, and see if the light turns off.

Sometimes, a dirty air filter can trigger the engine light. Check your air filter and clean or replace it if necessary.
