About ECU Engines

A Audi ECU (Engine Control Unit) is an electronic control system that manages and regulates the engine performance and efficiency via a series of actuators and sensors.

 

The ECU processes real time data taken from sensors such as air intake, exhaust gas, throttle position and crankshaft position, compares it to a ‘map’ or ‘lookup table’ and then adjusts components accordingly via actuators. Adjustments include changes to the engines timing, fuel/air mix and idle speed.

 

Some Engine Control Units also handle additional elements such as cruise control, anti-theft and anti-skid.

 

Audi ECU’s are located within the dashboard or engine bay. It is often possible to ‘read’ or interrogate your cars ECU 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 engine 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. Bad data from failed or degraded sensors are also common cause of ECU related faults.

Audi trivia

  • Volkswagen owns the Audi brand, after buying it from Daimler-Benz way back in the 1960s.
  • Not happy with just making one of the first automated cars, Audi even built and raced one in the Pikes Peak Hill race, setting records for speed even without a driver.
  • The Olympics Committee tried to sue Audi in 1995, claiming that the four rings logo was too similar to the Olympic rings. Audi easily won.
  • The Audi R8 is made very unusually, and only 20 are rolled out of their factory on any given day. That’s because it's considered an honour to work on this model, and only the top 120 Audi employees are qualified enough.
  • You might think that crash tests in cars have always been a requirement, but it was Audi that first started doing them. Far from the modern methods used today, Audi engineers simply let their cars roll down hills until they hit something. Spectators used to line up to watch the excitement.
