This could happen while speeding up on the highway on-ramp or cruising down a city street. These issues can create dangerous situations causing accidents and injury.
What is an air mass sensor on a Mercedes?
The Mass Airflow Sensor, MAF, is a key component in the process of the movement of fuel into and through your engine. This sensor measures the temperature of the air that flows over the wire and sends this information to the engine’s computer. This then determines the amount of fuel to be injected into the engine.
Can you drive with a bad mass air flow sensor?

The drivers can easily experience the lack of power in the engine, no-engine start, poor acceleration, and more during the drive.
Is it bad to drive a car with a bad MAF sensor?
Yes! It is possible to drive with the signs of a bad MAF sensor but for a specific duration.
