2024 Mercedes-Benz GLE-Class Coupe Check Engine Light Codes

Common check engine light codes for the 2024 Mercedes-Benz GLE-Class Coupe range from P0420 (catalyst efficiency) and P0300 (multiple cylinder misfires) to P0171/P0174 (lean fuel trim) and sensor-related codes such as P0135 (oxygen sensor heater). In Sudbury, MA, Mercedes‑Benz of Sudbury's certified technicians interpret each code in context, determining whether the issue is a sensor, exhaust component, ignition, or mechanical fault. Left unaddressed, these codes can lead to poor fuel economy, failed emissions tests, loss of power, and more expensive repairs like catalytic converter replacement or engine work. For example, a misfire code left unchecked can damage the catalytic converter, turning a relatively inexpensive ignition repair into a thousand-dollar exhaust job. We provide transparent estimates, OEM parts, and factory procedures to reduce long-term ownership costs. To get an accurate read and a clear plan, schedule service today and check our service specials for savings.

2024 Mercedes-Benz GLE-Class Coupe Check Engine Light Reset
