Common check engine light codes for a 2011 Mercedes-Benz E-Class E350 include oxygen sensor faults (P0130–P0167), catalytic converter efficiency (P0420), ignition coil or misfire codes (P0300–P0306), and battery/charging-related voltage codes. In Dallas, Park Place Motorcars Dallas diagnoses each code with Mercedes-specific tools to determine the underlying cause and the associated repair costs.
