Problem overview

Some Mini Cooper Countryman owners report experiencing issues with the check engine light, which can be triggered by various factors such as a faulty ECU, bad spark plugs, or other mechanical problems. Some owners note that if the check engine light remains constantly illuminated, it may indicate a malfunctioning engine control unit (ECU). Others have experienced an intermittent check engine light that activates after driving for a while and then turns off after a short break, suggesting underlying issues that require diagnosis with an OBD meter. Additionally, some owners report rough engine performance without any check engine light, which might point to a fuse issue or other mechanical concerns needing inspection. It is crucial for owners to address the check engine light promptly to prevent further damage, and regular maintenance practices, such as checking spark plugs, are recommended to help ensure the vehicle operates smoothly. Consulting a qualified mechanic or Mini Cooper dealership is advisable for accurate diagnosis and resolution of these issues.
