2024 Mercedes-Benz CLE Check Engine Light Reset

Resetting the check engine light on a 2024 Mercedes-Benz CLE is more than clearing a code; it requires verifying the underlying cause so the warning does not return. At Mercedes-Benz of Chesterfield, our approach begins with a full OEM diagnostic scan to identify stored and pending codes, interpret freeze-frame data, and test related systems like battery health, fuel trim, and emissions components. Simply clearing the light without addressing the fault risks repeated failures, reduced fuel economy, and potential long-term damage. Our technicians use Mercedes-approved tools and genuine parts to correct issues, ensuring the reset is reliable. We document all findings and present clear repair options, explaining immediate savings and how preventative service extends vehicle life. We also honor warranty requirements that mandate repairs be completed at certified dealerships to maintain coverage. To get a professional reset backed by testing and parts, schedule service or browse current service specials before your visit.

2024 Mercedes-Benz CLE Check Engine Light Codes
