    Compatibility should always be selected primarily by part number. If your vehicle originally uses ECU 21586141-0A, 9664242980 or software version SW9664242980, this module may be the correct replacement.

    Application of ECU 21586141-0A 9664242980

    • Peugeot Partner – selected petrol versions
    • Citroën C2 – selected petrol versions
    • Citroën C3 – selected petrol versions

    • Citroën Berlingo – selected petrol versions

    Depending on vehicle version, the ECU may operate with PSA petrol engines such as 1.4 16V and 1.6 16V. Before purchase, compare the original ECU number because engine size or vehicle model alone does not guarantee compatibility.

        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.
