2023 Mercedes-Benz EQS SUV Check Engine Light Reset

The process to reset a check engine light on a 2023 Mercedes-Benz EQS SUV should begin with a full diagnostic rather than a simple code clear.

At Park Place Motorcars Arlington in Arlington, TX, our certified Mercedes-Benz technicians use OEM-level diagnostic equipment to identify stored fault codes, perform necessary repairs or software updates, and then confirm the repair by clearing codes and retesting under normal operating conditions. This approach ensures you retain warranty protection — repairs covered under warranty must be performed at a certified dealership — and it avoids repeated trips and hidden expenses that can arise from incomplete fixes. We also offer clear, upfront pricing and flexible service financing so you can address urgent needs without delay. Before any reset we document findings, explain options, and apply genuine Mercedes-Benz parts, delivering transparency and peace of mind.
