About Speedometers

A vehicle’s BMW speedometer is a gauge or meter that measures the speed of a motor vehicle. Is does this by measuring the speed at which the wheels are rotating and communicating this to the BMW speedometer head, which then displays this as the vehicle’s speed.

There are two principal means by which the BMW speedometer system communicates the necessary information to the BMW speedometer head. The first of these is by way of a speedometer cable. This is a lengthy, flexible cable that comprises a collection of wires connected to the drive shaft, which turns as the wheels do. The rotation of the drive shaft causes the cable to turn which causes a magnet within a cup inside the speedometer head to turn. This causes currents that produce motion which, in turn, causes the BMW speedometer dial to move and demonstrate the vehicle’s speed.

The second means of transmitting information to the BMW speedometer head is electronically, by means of a BMW speedometer transducer. The BMW speedometer transducer is normally attached to the vehicle’s transmission and is an electronic pulse generator. It sends signals to the car’s computer as to how quickly the wheels are turning and this information is translated by the computer into the speed that is displayed by the BMW speedometer.

In either type of BMW speedometer system there are various components that are susceptible to failure but, fortunately, all of these are easily replaced.

BMW trivia

• The BMW 3.0CSL was sold in the 70s and had the unusual addition of a spoiler that was kept in the boot. The owner could install it if they wanted to, but BMW couldn't sell the car with the spoiler attached because of road laws!
• The BMW company was founded way back in 1916 and originally manufactured engines for planes. High demand for plane engines during WWI was good news for BMW, but they carried on making plane engines right up until 1945.
• The main headquarters for BMW in Munich is designed and shaped to look like car parts. There was a whole new 'four-cylinder' building added on in 1973, and there's definitely the look of an engine about the architecture.
• The famous German pilot, the Red Baron, called BMW engines the 'greatest in the world' and ‘the best engine in the war’.
• 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.
