In order to comply with the vehicle emission limits which is required by law, your BMW like most other vehicles are equipped with flow meters. Generally, your BMW doesn't have just one flow meter in it that take care of measuring different amount of gas or liquid being used by the engine. One of the flow meters installed in your BMW is the air mass meter. Your BMW air mass meter is used to measure the amount or the flow of air drawn into your cabin. This is necessary to maintain an exact air/fuel ratio. We all know that a good balance of this fuel/air mixture causes fuel economy and other benefits to your car. True to this fact, the car manufacturers installed your BMW air-mass meter in your cabin. The flow meter works like an oxygen sensor; it sends output through a corresponding electrical signal to the open and closed-loop control electronics or the on-board computer in that case. However, no car components last forever or have no weakness so far, and that includes your BMW air mass meter. There are common complaints which regard to the condition of the air mass meter as time goes by. Contamination is the common grounds for failure on these meters. Usual suspects include substances like silicone potting compound, dirt, oil and spider webs. Potting compound, used in the manufacture of the sensors to environmentally seal them can migrate onto their circuits. Oftentimes, the air mass meter displays defects through stalling and inconsistency, rough idle quality, poor throttle response, reduced fuel mileage and hesitation during acceleration.
