Mercedes-Benz C400 / C450 / C43 ECU Removal Guide
**** Note: Please disconnect battery, located in the trunk under the floor board, before disconnecting the ECU.
Open your vehicle’s hood:
The ECU can be seen in the center of the engine bay under the front engine cover. First we will need to remove the engine cover.
Lift back on each corner of the rear section of the engine cover. You will notice it will “pop” up easily with little effort.
Note that on the front portion of the engine cover, you will see two clips that will need to be disconnected from the air duct.
Pull back on these clips gently.
Once removed, place the engine over to the side.
You now see the ECU located in the center of the engine bay.
Located at the rear of the ECU, you will see the two ECU CONNECTORS.
Unlock the driver side connector.
Unlock the passenger side ECU connector
Pull up in the front of the ECU, you will notice the ECU will “un-clip”. Do the same for the rear.
Congratulations! The ECU has been removed!
