What is the first thing to check when the check engine light comes on?

• Start with simple checks: ensure the fuel cap is tight and inspect for obvious fluid leaks or severe smells.
• Check basic levels such as oil and coolant, but avoid DIY work beyond visual inspection on high-performance W12 engines.
