Check Engine Light Flashing

A flashing check engine light on a 2020 Mercedes-Benz Metris signals an urgent condition — often a misfire that can damage the catalytic converter or indicate serious electrical or ignition problems. Ignoring a flashing light risks more extensive repairs and higher costs down the line. At Park Place Motorcars Arlington our certified technicians in Arlington, TX use Mercedes-Benz diagnostic tools to read trouble codes, test ignition components, and verify battery and charging performance. If a battery, alternator, or starter issue contributes to the flashing light, we recommend OEM battery replacements and charging system repairs performed at our service center to preserve warranty coverage and vehicle longevity.
