I recently purchased a used Audi A4 and noticed that the check engine light is blinking. I'm not sure what the issue could be and would appreciate any help in troubleshooting.
ReplyStart by checking the code that is triggering the check engine light. You can do this by using an OBD-II scanner or taking it to a mechanic. Once you have the code, you can research online for possible causes or ask for assistance in online forums.
If your car is running fine and you don't notice any unusual noises or performance issues, it could be a minor issue. Try tightening your gas cap or replacing it if it's old or damaged. A loose gas cap can trigger the check engine light.
