What is the difference between ecu and ecm?

Ecu is short form for electronic control unit and ecm is short form for electronic control module. The main difference between these terms is that ecu is used for automotive applications while ecm is used in industrial applications.

Can you repair my BMW ecu/dme?

BMW ECUs/DMEs are computer systems that use electrical signals to control various functions in a car. When they become damaged, they may no longer be able to properly control the car’s engine and other systems.

In some cases, it may be possible to repair the ECU/DME, but it may also be necessary to replace it.
