2026 Mercedes-Benz S-Class Check Engine Light Reset

The check engine light reset on a 2026 Mercedes-Benz S-Class is not just about clearing a lamp — it’s about confirming the underlying issue was correctly diagnosed and repaired. Our technicians at Park Place Motorcars Dallas use Mercedes-Benz STAR diagnostic tools to read permanent fault codes, perform repairs with OEM parts, and then verify the repair by resetting and road-testing the vehicle. This process protects your vehicle’s health and resale value. A simple reset without repair can mask recurring faults and lead to more expensive long-term problems; that’s why we recommend dealer-performed service for lasting resolution. We are transparent about pricing and repair options, and we often cost less than independent shops once you account for correct parts and reliable workmanship. Warranty-covered repairs must be completed at a certified dealership to preserve coverage, and we make financing available so you can get necessary work done now and pay over time.
