2017 Mercedes-Benz E-Class Check Engine Light Codes

The 2017 Mercedes-Benz E-Class is monitored by a sophisticated onboard diagnostics system that generates standardized OBD-II codes when a fault is detected. In Dallas, Park Place Motorcars Dallas commonly sees codes related to oxygen sensors (P0130–P0167), catalytic converter efficiency (P0420), misfires (P0300–P0306), and evaporative emission system leaks (P0440–P0456). Left unaddressed, an oxygen sensor fault can reduce fuel economy and increase emissions, while catalytic converter problems can escalate into expensive replacements. Misfires often indicate worn ignition coils or spark plugs; untreated misfires can damage the catalytic converter and raise repair costs substantially. Evaporative system issues typically start small but can trigger ongoing fuel smell and failed emissions inspections if ignored. Our certified Mercedes-Benz technicians in Dallas use OEM procedures to diagnose the exact code, estimate repair costs, and explain how prompt service saves money long-term. We emphasize factory parts, technician training, and transparent work orders so customers understand immediate repair needs and the future savings of preventive maintenance.
