2024 Mercedes-Benz G-Class Check Engine Light Codes

The 2024 Mercedes-Benz G-Class uses advanced onboard diagnostics that report standardized codes when a fault is detected. Common codes often relate to oxygen sensors (affecting emissions and fuel economy), misfires (which can damage catalytic converters), and charging-system faults where a weak battery or failing alternator triggers errors. Ignoring codes tied to the battery or charging system can lead to starting failures, reduced electrical performance, and costly downstream damage like failed fuel pumps or electronic control module stress. At Mercedes‑Benz of Lynnfield, our certified technicians decode these fault codes, explain the likely root causes, and outline repair options with OEM parts so you avoid recurrent visits. We highlight immediate savings by fixing the root cause quickly and long-term savings through OEM-backed parts and workmanship that protect resale value. For a precise diagnosis and transparent pricing, schedule service or review our current service specials to reduce costs while receiving factory-level care.

2024 Mercedes-Benz G-Class Check Engine Light Reset
