2020 Mercedes-Benz Metris Check Engine Light Codes
The 2020 Mercedes-Benz Metris in Lynnfield, MA, can log a range of check engine light codes — from simple P0400 emissions codes to P0420 catalytic converter alerts and charging-related P06xx or Uxxxx codes tied to voltage. Common codes we see at Mercedes-Benz of Lynnfield often reflect oxygen sensor issues, catalytic efficiency, and battery/charging abnormalities. If left unfixed, oxygen sensor faults and catalytic problems can reduce fuel economy and lead to more expensive repairs such as oxygen sensor replacement or catalytic converter service. Charging and battery-related codes, if ignored, can damage starter systems, on-board electronics, and lead to unpredictable drivability. Our team uses Mercedes-Benz-approved diagnostic tools to identify the exact code, explain repair options, and present transparent pricing. That approach delivers both immediate savings — by fixing the true root cause quickly — and long-term savings by preventing collateral damage. For genuine OEM parts, expert technicians, and reliable service in Lynnfield, trust Mercedes-Benz of Lynnfield to diagnose and repair your 2020 Mercedes-Benz Metris correctly. Ready to get started?
