About Central Locking ECU

A 5 Series<Model> central locking ECU (Electronic Control Unit) is a microcomputer or brain responsible for management and control of a car’s central locking and security system. All locking components including the lock mechanisms, lock barrels, lock levers, actuators, remote sensors and other lock controls are electrically connected to the ECU, allowing it to regulate and control the overall state of the system. The central locking ECU may also control electric window closure, vehicle immobiliser and alarm system.

A 5 Series<Model> central locking ECU is located within the dashboard or engine bay. It is generally possible to ‘read’ or interrogate the central locking ECU using a laptop computer with relevant software and cable or a dedicated reader via a connection port usually located in the dashboard. This is the best method for diagnosis of central locking faults.
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 the ECU.

BMW 5 Series trivia

  • 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 BMW E39 5 Series made the top ten best list in Car and Driver magazine for six straight years, from 1997 to 2002.
  • The BMW 5 Series E39 was the first of the range to come with aluminium parts used in the front suspension. There was also a dramatic increase in the amount of aluminium used in the chassis. The goal was to reduce the overall weight of the E39, and the target was achieved by also adding in the first four-cylinder engine in a 5 Series.
  • Although it became an immediate bestseller, the BMW 5 Series is no longer BMW’s biggest selling vehicle (it’s the 3 Series). However, in January 2008 the five millionth 5 Series rolled off the production line. It was a 530 sedan and was a Carbon Black Metallic colour.
