Check Engine Light Flashing

The sight of a flashing check engine light in your 2024 Mercedes-Benz EQS is a clear indication that the vehicle’s on-board systems have detected a condition that could quickly affect drivability or battery performance.

At Mercedes-Benz of Sudbury in Sudbury, MA, our factory-trained technicians use OEM diagnostics to prioritize safety and prevent secondary damage. Fast diagnosis prevents deeper issues, such as diminished battery capacity, loss of regenerative braking efficiency, or electronic control unit complications that can be costly if delayed. We balance speed and precision—performing comprehensive scans, isolating the fault, and presenting clear repair options that emphasize long-term savings and peace of mind. Where warranty coverage applies, repairs must be completed at a certified dealership to preserve protection; our service team will assist with warranty claims and documentation. Take advantage of our current service specials and flexible service financing programs so you can address urgent needs without delay.

2024 Mercedes-Benz EQS Check Engine Light Reset

Resetting the check engine light on a 2024 Mercedes-Benz EQS is more than clearing a warning; it’s about confirming the underlying fault has been properly diagnosed and repaired.

At Mercedes-Benz of Sudbury our technicians follow factory procedures to verify repairs, use genuine OEM parts, and document service history—actions that preserve warranty coverage and vehicle value. We emphasize transparency: before any reset or repair we explain findings, offer a clear estimate, and discuss the immediate and long-term savings of factory-correct service. Doing the job right often costs less over time by avoiding repeat visits, incorrect parts, or unresolved faults that degrade EV performance.
