2010-2018 Sprinter W906 Diesel - ECU Cloning Service EDC17

The Mercedes EDC17 ECU (Engine Control Unit) is an advanced engine management system developed by Bosch and used in most Mercedes-Benz diesel models in the United States between 2009 and 2022. It is part of the EDC (Electronic Diesel Control) family and plays a crucial role in controlling engine performance, emissions, and efficiency.

The EDC17 ECU is specifically designed to meet modern emissions standards while maintaining the high performance and reliability of Mercedes-Benz diesel engines. It manages critical systems such as fuel injection, turbocharging, and emissions controls like the Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR).

Mercedes EDC17 ECU Variants

Different variants of the EDC17 ECU were used in Mercedes-Benz diesel vehicles depending on the engine type and model year:

1. EDC17CP10 (2009-2012 Models):

This variant was used in early diesel models equipped with the OM642 3.0L V6 Diesel engine.

2. EDC17CP46 (2013-2018 Models):

The EDC17CP46 replaced the EDC17CP10 in later diesel models with the OM642 3.0L V6 Diesel engine.

3. EDC17CP57 (2013-2022 Models):

This variant was used in vehicles equipped with the OM651 2.1L 4-cylinder Diesel engine and some newer models with the OM642 3.0L V6 Diesel engine, including the Sprinter W907.

Why is the EDC17 ECU Important?

The EDC17 ECU is a cornerstone of Mercedes-Benz diesel engine technology. It allows Mercedes-Benz to offer vehicles that deliver exceptional performance, reliability, and fuel efficiency while meeting strict environmental regulations.

If you own a Mercedes-Benz diesel vehicle from 2009 to 2022, your vehicle is likely equipped with an EDC17 ECU. Whether it’s the EDC17CP10 or EDC17CP46 for the OM642 3.0L V6 Diesel, or the EDC17CP57 for the OM651 2.1L 4-cylinder Diesel, the EDC17 ECU is critical to the operation of your engine.

This ECU is found in popular models like the Sprinter, ML-Class, GL-Class, E-Class, S-Class, and R-Class, ensuring that these vehicles deliver the performance and efficiency that Mercedes-Benz is known for.

ECU cloning is a process where the data from the original ECU is copied and transferred to a donor ECU. While cloning is possible on many Mercedes-Benz diesel models equipped with EDC17 ECUs, the process depends on the specific ECU variant and its security features. Here’s how cloning works for the most common EDC17 models:

1. EDC17CP10 (2009-2012 Models)

The EDC17CP10 ECU, used in earlier Mercedes-Benz diesel models with the OM642 engine, can typically be cloned 100% 1:1. This means the entire data set, including the security information, can be transferred directly from the original ECU to the donor ECU without additional steps.

This makes cloning straightforward and allows the donor ECU to work immediately without further programming or adaptation.

2. EDC17CP46 (2013-2018 Models)

The EDC17CP46, used in later diesel models with the OM642 engine, introduces more advanced security features.

• 1:1 Direct Cloning Not Always Possible:
  Many of these ECUs have anti-tampering mechanisms that prevent a full 1:1 cloning.
• Alternative Methods:
  In cases where direct cloning isn’t possible, the security information data (such as immobilizer codes and VIN) must be transferred from the original ECU to the donor ECU.

If transferring security data is not possible, the donor ECU must be virginized (reset to factory state), after which it will need to be adapted/programmed to the vehicle. This requires specialized tools like a dealer-grade scan tool or software such as Mercedes-Benz Xentry.

3. EDC17CP57 (2013-2022 Models)

The EDC17CP57, used in later models with both the OM651 engine and the OM642 engine (like the Sprinter W907), has even more stringent security features.

• 1:1 Direct Cloning Not Always Possible:
  Like the EDC17CP46, these ECUs often cannot be cloned directly due to security restrictions.
• Alternative Methods:
  The security information must be transferred from the original ECU to the donor ECU. If this is not feasible, the donor ECU must be virginized and programmed using tools like Mercedes-Benz Xentry or other dealer-grade diagnostic tools.

What Happens if Cloning Isn’t Possible?

If cloning directly or transferring security data is not possible, the donor ECU must be virginized. Virginizing resets the ECU to a blank factory state, allowing it to be adapted to the vehicle. This process requires:

1. Virginizing the Donor ECU:
   
   This removes all previous data and prepares the ECU for programming.
2. Programming the Virginized ECU:
   
   A dealer-grade scan tool or software like Mercedes-Benz Xentry is required to adapt the virginized ECU to the vehicle. This involves:

• Programming the immobilizer system.
• Matching the VIN and other security data.
• Performing any necessary software updates.

To ensure a donor ECU is compatible with your vehicle, it is essential to verify that the hardware and software specifications match between your original EDC17 ECU and the donor ECU. Here are the key steps to confirm compatibility:

1. Match the Bosch Part Number (0 261 xxx xxx / 0 281 xxx xxx)

The Bosch part number is a unique identifier for the ECU's hardware and internal architecture. It is printed on the ECU sticker and typically starts with 0 261 or 0 281.

• Why It’s Important:
  
  Matching the Bosch part number ensures that the donor ECU has the same hardware design and capabilities as the original. A mismatch could result in improper functionality or incompatibility with your vehicle's systems.

2. Match the Mercedes-Benz Part Number

The Mercedes-Benz part number is another critical identifier found on the ECU sticker. This number is specific to Mercedes-Benz and reflects the ECU's compatibility with the vehicle's software and configuration.

Why It’s Important:

Even if the Bosch part number matches, the Mercedes part number must also match to ensure the ECU works correctly with the vehicle's immobilizer, engine, and other systems.

Example:

If your original ECU has the Mercedes part number A 642 150 12 91, the donor ECU must have the exact same number.

Why Matching Part Numbers is Crucial

Failure to match the Bosch and Mercedes part numbers can result in:

1. Immobilizer Issues: The ECU may not communicate with the vehicle's immobilizer, preventing the engine from starting.
2. Software Conflicts: The donor ECU may not have the correct software for your vehicle's configuration.
3. Hardware Incompatibility: Differences in hardware design could lead to improper functioning or damage to the vehicle's systems.

By carefully matching the part numbers and verifying compatibility, you can avoid these issues and ensure a successful ECU replacement.

We don't keep or sell many ECU donor units due to their numerous variations.
It's recommended to buy a replacement unit that exactly matches your original
one. Once you've acquired the matching ECU module, you can send us the
replacement ECU module and the original ECU module for cloning programming process.

Replacement with EDC17CP46 After Emissions Recall

Following the Mercedes-Benz emissions recall (related to updated emissions standards and compliance), many vehicles originally equipped with the EDC17CP10 were upgraded by dealers to the newer EDC17CP46 ECU.

• Why the Replacement?
  
  The EDC17CP46 features updated hardware and software designed to meet stricter emissions regulations while maintaining performance. This replacement was often performed as part of the recall to ensure compliance with updated standards.
• Impact on Vehicles:
  
  Vehicles that underwent this replacement required the new ECU to be programmed and adapted to the vehicle’s systems using dealer-grade tools like Mercedes-Benz Xentry.

Key Points to Note

• The EDC17CP10 was a robust and widely used ECU for OM642 engines during 2009-2012.
