How to choose the correct ECU for a Porsche Cayenne diesel
This unit carries OEM part number 7P5907401D and Bosch part number 0281017906. The label also shows the designations EDC17CP44, CRCA and HW: H37, which help distinguish this ECU from other units used in the Cayenne.
Vehicle compatibility
- Porsche Cayenne 3.0 diesel – selected versions.
First of all, compare the complete OEM part number 7P5907401D, including the final letter D, and Bosch number 0281017906 with the label on your original ECU. Also check the H37 hardware designation and the other version markings. The vehicle model or EDC17CP44 ECU family alone is not sufficient to confirm compatibility.
If any of the markings are different, please send us a clear photo of the original ECU label together with the vehicle VIN before purchasing so that compatibility can be checked.
Preparation and installation
The ECU offered here requires programming. Before installation, confirm with your workshop that they can prepare the ECU for your specific vehicle and determine what programming and adaptation will be required.
- Confirm the part numbers and hardware version before purchasing.
- Arrange the necessary programming before using the ECU in the vehicle.
- Keep the original ECU until the replacement process has been completed and the vehicle has been tested.
