2021 BMW X6 M Check Engine Light Codes

Common check engine light codes for the 2021 BMW X6 M involve oxygen sensors (O2), mass airflow (MAF) sensors, misfire codes, and catalytic converter efficiency codes.

At Herb Chambers BMW Certified Preowned Medford, our factory-trained technicians diagnose root causes and explain the cost implications of delaying repair—small sensor fixes prevent expensive catalytic converter or engine damage down the road. We emphasize immediate and long-term savings: accurate OEM diagnostics avoid unnecessary parts replacement, and proper repairs maintain efficiency and resale value.
