    55250921 CFC328F.02 – Selespeed Gearbox Control Module Fiat 500

    55250921 / CFC328F02 is an original Selespeed gearbox control module used in Fiat 500 models equipped with the automated manual Selespeed transmission. The module is responsible for full control of gearbox actuators, gear shifting, clutch operation, and communication with other vehicle systems (including engine ECU, ABS, Body Computer).

    The most important selection criterion is compatibility by part number. If your module shows number 55250921 or system designation CFC328F.02 / CFC328F02, the offered control unit will be hardware compatible.

    Technical specification

    • OEM number: 55250921
    • Manufacturer designation: CFC328F.02 / CFC328F02
    • Transmission type: Selespeed (automated manual)
    • Application: Fiat 500
    • Condition: fully tested, bench-tested on diagnostic station
    • Warranty: yes

    Application – compatibility by part number

    The gearbox control module 55250921 CFC328F.02 was used in:

    • Fiat 500 1.2 8V (169A4.000) – approx. years 2008–2015
    • Fiat 500 1.4 16V (169A3.000) – selected versions with Selespeed transmission
    • Selected European market configurations with semi-automatic gearbox

    Function of the Selespeed gearbox control module

    The CFC328F.02 module is responsible for:

    • clutch actuator control,
    • managing gear selection and shifting,
    • control of the hydraulic system pressure,
    • CAN communication with other vehicle modules,
    • automatic and manual (sequential) mode.

    Failure of the control module may manifest itself as: inability to change gears, gearbox emergency mode, CAN communication errors, jerking during take-off, or transmission fault message.

    Why is compatibility by number 55250921 crucial?

    In the case of Selespeed transmissions, the same car model may appear with different control unit versions. Therefore:

    • we do not select only by car model,
    • we do not select only by production year,
    • we always verify by OEM number from the module label.

    If your control unit is marked CFC328F02 and number 55250921, this unit will be the correct choice.

    FAQ – Frequently Asked Questions (Q&A)

    Does control module 55250921 fit Fiat 500 1.2 8V from 2010?
    Yes, provided that the original module shows number 55250921 or designation CFC328F.02. Compatibility is always confirmed by part number.

    Difference between CFC328F.01 and CFC328F02 in Fiat 500 1.4 16V?
    These are different hardware and software versions. Control module CFC328F02 (55250921) should not be replaced without full number compatibility.

    Does 55250921 CFC328F.02 require programming after installation in Fiat 500?

    Which engines use gearbox control module 55250921 in model 500?
    Most commonly used in versions 1.2 8V (169A4.000) and selected 1.4 16V (169A3.000) with Selespeed transmission.

    Fiat 500 Selespeed – no gear change, could CFC328F.02 be faulty?
    Yes, one of the common causes of gear selection problems is failure of gearbox control module number 55250921, however full diagnostics is recommended before replacement.

        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.
