About Mass Air Flow Sensors. MFR: AIP Electronics. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. A mass airflow sensor (MAS) determines the mass of air entering a vehicle's fuel injection engine, and passes that data to the Engine Control Unit, or ECU. these are made by either BOSCH or VDO (siemens) depending what is OEM on your BMW. Saab mechanics clean these all the time. It helps the car's computer regulate the ratio of air to fuel. Tried to go through the return process with 1A Auto but the process was not good - did not work. It is important that your MAF sensor is working properly to ensure the best fuel efficiency and engine function.
