Unfortunately, there are numerous reasons that could trigger the check engine light in a 2010 Audi Q5, making it challenging to pinpoint a specific issue for you. The check engine light serves as a general indicator for diagnostic trouble codes that can be read using an OBD-II scan tool. It simply signals that you need to retrieve your code(s) without providing precise details on the problem. Possible causes might include a malfunctioning fuel pump, a loose gas cap, an EVAP emissions leak, defective spark plugs, or various sensor failures. To narrow down the issue, you can search online resources like Vehicle History or other sites using the DTC information obtained from your OBD-II. If you don't have access to a scan tool, most major auto parts stores usually offer free vehicle scanning services.
