2025 Mercedes-Benz CLA-Class Check Engine Light Codes

In Dallas, drivers trust Park Place Motorcars Dallas for thorough code diagnosis on the 2025 Mercedes-Benz CLA-Class. Common codes include P0420 (catalyst system efficiency), P0171 (system too lean), P0300 (random/multiple cylinder misfire), and various oxygen sensor faults. If left unchecked, a P0420 can lead to reduced catalytic converter life and emissions failures, driving repair costs into the thousands; a P0171 or oxygen sensor fault will degrade fuel economy (25 MPG city / 34 MPG highway becomes worse) and can damage downstream components. A misfire code risks catalytic damage and could leave you stranded. Our certified Mercedes-Benz technicians use OEM diagnostic tools to identify the exact cause, provide a clear estimate, and perform repairs that protect long-term vehicle value. Choosing Park Place Motorcars Dallas in Dallas, TX means factory-trained service, genuine parts, and fast turnaround that often delivers immediate and sustained savings versus repeat visits elsewhere.
