2022 Mercedes-Benz GLE-Class Coupe Check Engine Light Codes

Common diagnostic trouble codes on a 2022 Mercedes-Benz GLE-Class Coupe include P0300 (random/multiple misfires), P0420 (catalyst system efficiency below threshold), P0171 (system too lean), and P0442 (evaporative emission control small leak). Left unchecked, P0300 can lead to rough running, higher emissions, and a damaged catalytic converter—replacement of which is costly compared to early repairs. P0420 often begins as a failing oxygen sensor; delaying diagnosis can necessitate converter replacement. P0171 and P0442 commonly cause reduced fuel economy and recurring faults if not addressed. At Mercedes-Benz of Lynnfield in Lynnfield, MA, our technicians use manufacturer-grade tools to identify whether a sensor, gasket, or system failure is the root cause. We provide transparent repair estimates, OEM parts, and technician-backed warranties—repairs performed at our dealership help protect any remaining coverage. Quick, accurate diagnosis reduces downtime and long-term expense; to get started, schedule service and ask about our current service specials.

2022 Mercedes-Benz GLE-Class Coupe Check Engine Light Reset

Resetting the check engine light on a 2022 Mercedes-Benz GLE-Class Coupe without addressing the underlying fault may mask symptoms and allow damage to progress.

This ensures transparency, preserves warranties, and delivers measurable long-term savings by preventing repeat failures.

Before any reset, our technicians will review the code history and recommend the correct repair path; we’ll only clear codes after confirming the issue is resolved.
