I recently noticed my Audi A4's engine malfunction warning light has turned on. I checked the manual and it says to immediately contact a mechanic. But before I do, is there anything I can quickly check or troubleshoot on my own?
ReplyThe most common cause of the engine malfunction light turning on is a loose gas cap. Make sure it is properly secured and see if the light turns off. If not, you may need to take it to a mechanic for a diagnostic.
