About Air Flow Mass Sensors

The BMW air flow mass sensor is an electronic air flow sensor, also referred to as an air flow mass meter, which measures air flow; the mass of air which is flowing through the car's engine, and is an important part of the Engine Control Unit (ECU).  The BMW air flow mass sensor has an important part to play in the performance, power and efficiency of the car's engine.

The BMW air flow mass sensor is usually found in the plastic housing between the engine and the air filter.  It is attached to the BMW air hose at one end and the BMW air filter box at the other.

The engine needs the correct amount of air and fuel flowing through it in order for the fuel to burn in the cylinders and for the engine to ignite or spark at the right time. If the ignition sparks at the wrong time, there will be less power in the engine and it will try to make up for this by using more fuel, significantly reducing fuel efficiency, which in turn increases the car's CO2 emissions. The BMW air flow mass sensor works by measuring the air flow and sending these measurements to the car's ECU which, based on these measurements, will control the amount of fuel flowing into the engine at the point at which the ignition sparks.

The BMW air flow mass sensor will, with continued use, wear out or stop working. When this happens, the performance of the engine is likely to be affected and engine emissions will be higher. A fault in the BMW air flow mass sensor will cause the Check Engine light to show on the dashboard to indicate a problem with the BMW air flow mass sensor. A broken air flow mass sensor can sometime prevent a car from idling properly (the ability for a car's engine to run whilst it is not moving) and may cause the engine to splutter and stall. If there is a fault in the BMW air flow mass sensor a replacement BMW air flow mass sensor should be purchased.

BMW trivia

• The very first BMW was named the 'Dixi'. They hadn't designed it (it was really an English Austin), and they dropped the name 'Dixi' very quickly, instead opting for the rather more grandiose BMW 3/15 DA-2. Rolls off the tongue!
• Think you know what BMW is an acronym of? If you answered Broke My Wallet, you’re definitely wrong. It really stands for Bayerische Motoren Werke (which is Bavarian Motor Works in English).
• That distinctive BMW car engine sound that new owners fall in love with might not be real. The BMW M5 has such a quiet engine that they had to install fake engine noises to keep drivers happy!
• The BMW M1 has a classic look, so it's no surprise that its designer also came up with some other amazing car designs. Giorgetto Giugiaro is also responsible for the DeLorean, the Beretta U22 Neos handgun, and the Nikon D4 camera! Although, he also designed the Yugo, commonly called the worst car that's ever been made.
• One of the reasons older BMWs keep their value is because it's easy to get spare parts for even the oldest models. That's because BMW has carried on making car parts, even for cars that were built in WWII.
