How to match Citroen engine control units by part number
The engine control unit (ECU) manages injection, ignition and the throttle based on sensor signals. That is why a replacement is chosen by the numbers on its label: the electronics manufacturer's number and the Citroen OEM number. The car model and engine size alone are not enough, because one model can come with several ECU versions.
Numbers and markings of Citroen control units
Among Citroen listings you will meet ECU families such as HDI. The family marking is only part of the identification, so always check the full number on the label. The Bosch number 0281012984 is sometimes written as 0 281 012 984, so search both ways. Engines in the listings here include 1.4 HDI, 1.6 HDI.
