About ECU
What is the ECU/what does it do?
The term ECU (Electronic Control Unit) is a universal name given to a variety of electronic control systems found in a car. Collectively they make up the car's computer or brain which controls and regulates key components of the vehicle.
Getting into the details of the ECU
ECU’s are located within the dashboard or engine bay. It is often possible to ‘read’ or interrogate your car's various ECU’s using a laptop computer with relevant software and cable or a dedicated reader via a connection port which is usually located in the dashboard. This method is used by mechanics for diagnosis of certain vehicle faults.
An ECU controls or governs aspects of a car's systems including, but not limited to, the engine, ABS, suspension, automatic gearbox and power steering.
What if something goes wrong with the ECU?
Like any electronic component an ECU can fail for a number of reasons including short circuits, dry solder joints, water damage or age. Diagnosis is generally much easier with the correct reader which can be used to obtain error codes from ECU.
BMW 3 Series trivia
- The combined sales of every 3 Series model adds up to around 14 million units, which puts it in the ranks of the best selling cars of all time.
- The E21 Baur convertible was the first left-hand-drive 3 Series and was launched in 1977.
- Sales figures for the 3 Series went through the roof in the 1980s, thanks to the rise of Yuppies. Although BMW made a lot of sales, ultimately, the association harmed the BMW brand for a few years until the association with Yuppies started to fade
- Although the E21 sold around 1.36 million units, that seems insignificant compared to the E30 3 Series that launched in 1982 and sold 2.2 million units!
- The 3 Series Touring wasn’t a planned production model. It was actually designed by a BMW engineer called Max Reisbock, who used his spare time to convert a damaged 323i so that it was more suitable for his family. When his bosses saw the result, they made a few tweaks and then built a factory version.
