How do I troubleshoot my Audi 80's engine light?

Recently, the engine light on my Audi 80 has been turning on sporadically. I want to know how I can troubleshoot the issue and possibly fix it myself.

First, you'll want to check your gas cap to make sure it is tightly sealed. A loose gas cap can sometimes cause the engine light to turn on. If that doesn't solve the issue, you can bring your car to a mechanic or use a OBD-II diagnostic tool to find out the specific error code causing the light to turn on.

It's also a good idea to check your air filter and spark plugs. A dirty air filter or faulty spark plugs can sometimes cause the engine light to turn on.
