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?
In most cases gearbox adaptation / calibration is required using a diagnostic tester supporting the Selespeed system.

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.

1. Are the electronic modules tested before shipping?

Yes. Every electronic module, including ECU ENGINE CONTROLLERS, ABS pumps, BSI, BCM, comfort modules, transmission controllers and other automotive electronics, is electronically tested before shipping. We verify communication, power supply and basic operation to ensure the product is working correctly before delivery. This allows you to receive a tested and ready-to-install unit.

2. Does the module require programming or coding after installation?

It depends on the product version and the type of module. We offer VIRGIN, IMMO OFF and Plug & Play solutions. Information about programming or coding requirements is always included in the product description. In many cases, installation is possible without additional coding, while some modules may require adaptation using diagnostic equipment.

3. How can I choose the correct module for my vehicle?

The most important step is comparing the part numbers from your original module. Please check the Bosch, Siemens, Magneti Marelli, Continental or OEM manufacturer numbers on the label. If you are unsure, you can send us a photo of your original module or your vehicle VIN number and we will help verify compatibility.

4. Are the products covered by warranty?

      Water-Damaged Bosch 0281013691 / 4L0910401K ECU – Common Audi Q7 3.0 TDI Engine Control Unit Failure

      Water Damage in Bosch 0281013691 / 4L0910401K ECU – A Common Audi Q7 3.0 TDI Failure

      The Bosch 0281013691 / 4L0910401K engine control unit fitted to the Audi Q7 3.0 TDI 4L is well known for being vulnerable to water damage. In many cases, the issue is caused by the ECU’s location beneath the windshield cowl, where moisture and rainwater can accumulate over time due to blocked drainage channels.

      Symptoms of a failing ECU may appear gradually or occur suddenly after heavy rain, a car wash, or long periods of vehicle inactivity. Common signs include no communication with the engine control module, intermittent or complete no-start conditions, CAN bus communication faults, and in severe cases, a completely dead ECU in the Audi Q7 3.0 TDI.

      Similar problems frequently affect other Bosch EDC16CP34 units installed in the same location, including 0281012772 / 4L0907401, 0281012919 / 4L0907401, 0281013689 / 4L0910401M, and 0281013690 / 4L0910401L. These engine control units share nearly identical hardware architecture, with the main differences relating to software versions and vehicle-specific configuration used across different Audi Q7 3.0 TDI variants.

      In this article, we explain the most common failure symptoms of the 0281013691 / 4L0910401K ECU, the typical causes of water intrusion, CAN communication issues, and a practical solution in the form of a ready-to-install IMMO OFF Plug & Play engine ECU that works without immobilizer programming or data cloning.

      Mercedes, Fiat, Peugeot & Citroën Transmission Control Module – How to Choose and Repair the Right Gearbox ECU

      Automatic Transmission Control Module – Diagnostics, Common Fault Symptoms and TCM / EGS Repair

      The automatic transmission control module is one of the key electronic components responsible for gear shifting, communication with the engine ECU, and the overall operation of the automatic gearbox. A failure of the TCM, EGS, VGS, ISM or Dualogic module can lead to transmission limp mode, harsh shifting, inability to engage gears, CAN communication faults, “Transmission Fault” warning messages, or even a complete no-start condition.

      In many cases, the issue is related to the transmission electronics rather than a mechanical failure of the gearbox itself. Before considering an expensive transmission rebuild or replacement, it is highly recommended to perform proper diagnostics of the automatic transmission module and verify communication with the TCM or EGS controller.

      On the ECUSALE blog, we publish detailed guides covering the diagnostics, repair and selection of automatic transmission control modules for Mercedes, Fiat, Peugeot and Citroën vehicles. We explain the most common symptoms of faulty TCM and Dualogic units, the differences between VIRGIN, cloning and Plug & Play solutions, and when it is possible to repair the transmission controller without replacing the entire automatic gearbox.
