2015 Mercedes-Benz GLK-Class Check Engine Light Codes

The 2015 Mercedes-Benz GLK-Class BlueTEC uses a diesel-specific emissions and engine management system that commonly reports codes tied to the DPF (diesel particulate filter), SCR/AdBlue system, turbocharger boost sensors, and fuel-delivery components. Typical codes for Arlington owners include DPF restriction alerts, NOx or AdBlue dosing faults, and boost-pressure deviations. Ignoring these codes can escalate costs: a clogged DPF can force frequent regenerations and ultimately require a costly replacement, SCR failures may disable emissions compliance and trigger limp mode, and turbo issues quickly reduce performance and fuel economy. At Park Place Motorcars Arlington our service team diagnoses codes with OEM-grade tools, explains each fault and the cost of deferred repairs, and recommends the most cost-effective path forward. We emphasize immediate savings through correct repair and long-term value by preserving engine life and resale worth.
