The mass airflow sensor in your Mercedes-Benz GL 350 is what determines how much fuel is needed to run your engine efficiently by measuring the reward of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to competent changes, like altitude. If your Mercedes-Benz GL 350 is having trouble starting, idling rough or has a fast change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.

Over time, vacuum hoses can dry out and crack, highly if they’re exposed to intense heat or extreme congenial.
  • Your O2 Sensor (Oxygen Sensor) needs to be replenished. The Oxygen sensor, known as the O2 sensor, measures the reward of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less favorable when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A faulty sensor can not only affect your miles per gallon, but it can cause damage to your catalytic converter and your 2012 Mercedes-Benz GL 350's spark plugs.
