2025 Mercedes-Benz GLE-Class Check Engine Light Reset

Resetting the check engine light on a 2025 Mercedes-Benz GLE-Class is not a substitute for proper diagnostics. While some drivers clear codes with a scan tool, the light will return until the underlying issue is resolved — and clearing codes can erase important freeze-frame data that helps technicians diagnose intermittent faults. At Mercedes-Benz of Sudbury, we pair an initial code read with a targeted inspection, OEM replacement parts when needed, and a detailed repair record so you understand both immediate and long-term benefits. Our dealership offers warranty-backed repairs, and any warranty-covered work must be performed at a certified Mercedes-Benz service center to remain valid. We also provide service financing and transparent, itemized estimates so you can make informed choices that protect your vehicle’s performance and value. For a reliable reset and lasting repair, schedule service with our team and review current service specials to save on maintenance.
