What does it mean when the check engine light comes on in a 2016 Mercedes-Benz B-Class Electric Drive?

• On an electric model this light may indicate powertrain or charging-system issues, battery or module temperature irregularities, or electronic control problems rather than traditional combustion faults.

• Park Place Motorcars Fort Worth uses factory-trained technicians and Mercedes-Benz diagnostic equipment to identify the root cause quickly, minimizing unnecessary parts replacement and saving you money over time.

• Record any immediate behavior — reduced power, charging interruptions, or unusual noises — and bring the car to Park Place Motorcars Fort Worth for a professional scan if you see abnormal symptoms.
• Attempting resets at home can mask underlying issues and may affect warranty; certified diagnostics at our dealership protect immediate and long-term value.

What is the most common reason for the check engine light on a 2016 Mercedes-Benz B-Class Electric Drive?
