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 5 Series trivia

  • Since its original run, there have been over 7.5 million BMW 5 Series sold around the world. Without the incredible success of the BMW 5 Series, the future of BMW could have been very different.
  • The main buying demographics of the BMW 5 Series are predominantly Millennials, but it’s very much a car that men prefer. Research in 2019 showed that more than 64% of 5 Series owners are male.
  • We all recognise the three-digit naming convention that BMW uses, but it was the 5 Series that started it all off. That means the 5 Series was the very first BMW to use the word ‘series’ in its official name.
  • Thanks to its sales figures and continuous placement on both owner and expert polling lists, the BMW 5 Series has been named the most successful car of all time.
  • The original BMW 5 Series was only available in the sedan model and only came with a manual gearbox as standard.
