Check Engine Light Flashing

At Park Place Motorcars Arlington in Arlington, TX, our certified Mercedes‑Benz technicians prioritize urgent diagnostic service, isolating ignition, fuel delivery, and sensor failures rapidly. We use OEM parts and manufacturer-level diagnostics to pinpoint misfires, replace faulty coils, plugs, or injectors as needed, and ensure the catalytic system remains protected.

2024 Mercedes-Benz CLA-Class Check Engine Light Codes

Common diagnostic trouble codes for the 2024 Mercedes-Benz CLA-Class include P0420 (catalyst efficiency), P0171/P0174 (fuel trim/system lean), P0300–P0304 (random or cylinder misfires), and O2 sensor codes.
