The check engine light in your 2013 BMW X5 can be triggered by several common issues, including:
- Loose or Faulty Gas Cap: A loose or damaged gas cap can disrupt fuel system pressure, causing the light to activate.
- Faulty Oxygen Sensor: Oxygen sensors monitor unburned oxygen in the exhaust. Failure can lead to poor fuel economy and higher emissions.
- Catalytic Converter Issues: A failing catalytic converter can increase harmful emissions and trigger the light.
- Spark Plugs or Ignition Coil Problems: Worn spark plugs or ignition coils may cause engine misfires, reducing fuel efficiency.
- Mass Airflow Sensor Fault: This sensor monitors air intake. When it malfunctions, it can impact fuel economy and engine performance.
- Evaporative Emissions System Leak: Leaks in this system, which controls fuel vapor emissions, can also trigger the check engine light.
In any case, this 2006-2013 BMW X5 (E70) Service & Repair Manual should be able to help you diagnose the issue and pinpoint the exact cause.
