2017 Mercedes-Benz GLE-Class Coupe Check Engine Light Codes

The most common check engine light codes for a 2017 Mercedes-Benz GLE-Class Coupe in Lynnfield reflect sensor or combustion issues: P0420 (catalyst efficiency), P0171/P0174 (lean condition), P0300-P0306 (misfires), and oxygen sensor codes. Ignoring these codes can escalate costs quickly — a bad oxygen sensor can reduce fuel economy immediately and, if left unchecked, lead to costly catalytic converter damage (often exceeding $1,000). Misfires risk engine damage and can ruin spark plugs or pistons; a lean condition can overheat components, increasing repair scope. At Mercedes-Benz of Lynnfield our technicians interpret codes with OEM-grade scanners and verify issues before replacing parts, saving you money now and over time. We provide clear estimates, OEM parts, and explain warranty implications so you avoid unnecessary expense.
