Check Engine Light Flashing

At Mercedes-Benz of Sudbury our team is equipped to perform rapid diagnostics to determine whether the issue is a misfire, ignition fault, or sensor failure. We prioritize urgent cases and can often provide same-day attention; we also discuss OEM repair options and long-term costs so you can make an informed decision.

2025 Mercedes-Benz E-Class Check Engine Light Reset

Resetting the check engine light on a 2025 Mercedes-Benz E-Class may seem simple, but without addressing the underlying code it will likely return and could mask ongoing damage. Our technicians at Mercedes-Benz of Sudbury use diagnostic-grade tools to read and clear codes only after repairs are completed or to verify intermittent faults during a controlled test. We emphasize transparency: you get a clear report of codes, recommended OEM repairs, estimated costs, and warranty coverage. Performing resets and repairs with OEM parts and certified procedures protects your vehicle warranty and ensures repairs are done to factory standards. We also explain the difference between a temporary reset and a permanent repair so you understand when a reset is appropriate.

2025 Mercedes-Benz E-Class Check Engine Light Codes

Common check engine light codes for a 2025 Mercedes-Benz E-Class include P0420 (catalyst efficiency), P0300–P0304 (misfire codes), and P0130–P0167 (oxygen/air-fuel sensor circuits). Left unaddressed, these faults can lead to decreased fuel economy, higher emissions, and expensive repairs such as catalytic converter replacement. At Mercedes-Benz of Sudbury we explain the cost implications of delaying repair: a failed oxygen sensor can reduce efficiency and damage downstream catalytic components, while misfires can rapidly ruin the converter. Our certified technicians diagnose codes precisely and recommend OEM parts and service intervals that minimize lifetime ownership costs. We take pride in quick turnarounds, transparent estimates, and options like service financing to make needed repairs manageable.
