    0281017236 A6409003700 Engine ECU for Mercedes B-Class W245 B200 CDI 2.0

    The offered Bosch engine ECU 0281017236 with Mercedes part number A6409003700 is designed for the Mercedes-Benz B-Class W245 B200 CDI 2.0. The unit is supplied in VIRGIN condition, meaning it has been reset and prepared for programming and adaptation to another vehicle.

    This is not a Plug & Play version. After installation, the ECU requires programming and coding to the vehicle using suitable diagnostic equipment, most commonly Mercedes Star Diagnosis / Xentry. During the adaptation process, the control unit must be synchronized with the immobilizer system and vehicle configuration.

    Compatibility – 0281017236 A6409003700 ECU

    • Mercedes-Benz B-Class W245
    • B200 CDI 2.0 diesel
    • OM640 engine family
    • typically production years: 2005–2011
    • Bosch / Mercedes CR40 engine control unit

    Before purchasing, compare the part number from your original ECU label. The key references to verify are 0281017236 and A6409003700. Matching the part number is the safest way to ensure compatibility.

    ECU preparation

    The ECU has been fully tested, communication checked, and prepared in VIRGIN condition. This means it can be adapted again to another vehicle but requires programming after installation.

    Possible symptoms of a faulty engine ECU

    • no communication with the engine ECU,
    • engine will not start,
    • immobilizer or start authorization faults,
    • injector power supply problems,
    • irregular engine operation on the B200 CDI,
    • CAN communication errors or no start permission,
    • check engine light and stored ECU fault codes.

    Programming after installation

    After installing the 0281017236 / A6409003700 ECU, adaptation must be carried out in the vehicle. The recommended tools are Mercedes Star Diagnosis or Xentry. The process generally involves installing the ECU, connecting to the vehicle, performing engine ECU adaptation, and synchronizing it with the immobilizer system.

    • ECU engine controller and ABS pump manufacturers – how to choose Bosch, Delphi, Continental, Magneti Marelli, Siemens, FoMoCo, Visteon and ATE

      Basic Information 02-07-2026

      Most popular automotive electronics brands – how to choose the right module?

      On the ECUSale blog, we have prepared a practical guide to the most popular automotive electronics manufacturers, such as Bosch, Delphi, Continental, Magneti Marelli, Siemens, FoMoCo, Visteon, ATE and FPT. We explain which engine ECU controllers, ABS pumps, BCM, BSI, BSM modules and gearbox controllers are commonly found under specific brands.

      You will also learn why the most important details when choosing a replacement part are the ECU part number, OEM number, HW/SW version and vehicle configuration, not only the module’s appearance or manufacturer brand. We also explain when cloning, a Virgin version, Plug & Play preparation or IMMO OFF may be required.

    • Audi Q7 3.0 TDI Water Damaged Engine ECU| 4L1910401D & 4L0910401G IMMO OFF Plug & Play

      Basic Information 22-05-2026

      Audi Q7 3.0 TDI won’t start after heavy rain? The engine ECU could be water damaged

      One of the most common failures in the Audi Q7 3.0 TDI is water damage affecting the Bosch EDC17CP04 engine ECU. This issue frequently impacts units 0281015868 and 0281014174, which are mounted beneath the windscreen scuttle panel, an area highly exposed to moisture and blocked drainage channels that can lead to corrosion inside the ECU.

      In this article, we explain the typical symptoms of a failed Audi Q7 3.0 TDI engine control unit, when ECU cloning is still possible, and why in many situations an IMMO OFF Plug & Play solution is the fastest and most reliable repair option.

      0281015868 & 0281014174 – common ECU failures in the Audi Q7 3.0 TDI

      Learn why engine ECUs such as 4L1910401D and 4L0910401G are especially vulnerable to water ingress, which fault codes usually appear during diagnostics, and how professional ECU repair or replacement is performed for the Audi Q7 3.0 TDI.
