Check Engine Light Flashing

A flashing check engine light on a 2022 Mercedes-Benz EQS is a serious indicator that a misfire or immediate powertrain fault may be occurring and requires prompt attention.

At Mercedes-Benz of Lynnfield in Lynnfield, MA, our certified technicians are trained on EQS-specific systems and use dealer-level diagnostic equipment to isolate the condition quickly. We prioritize safety and accuracy: if towing is required we coordinate the process, and if a repair or module replacement is necessary we install genuine OEM parts and follow factory procedures to retain warranties.
