Mercedes engine control units – find yours by part number
We have more than 40 used Mercedes engine control units (including Siemens, Bosch and Temic). Each one is listed with the numbers from its label, so you can compare it with yours. Looking for a specific number? Write to us with the number from the label and we will check whether we have it.
List of products
Mercedes engine ECU: number, engine, year
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 Mercedes 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 Mercedes control units
Our Mercedes control units include families such as ESP. The family marking alone is not enough to match a part; you need the full number. The Bosch number 0281012065 is sometimes written as 0 281 012 065, so search both ways. Engines in the listings here include 2.5 TDI.
More numbers from our stock: 0145459032, 0261206300, 0281001463, 0281010851.

Frequently asked questions
| Do used Mercedes control units need programming? | It depends on the version. A used ECU holds the data of the previous car, so it may need adaptation or programming. The available options are described on the ECU preparation options page. |
