A faulty transmission control module (TCM) most often causes limp mode with the gearbox stuck in one gear, harsh jolts when you select D or R, erratic gear changes, flashing PRND letters and a gearbox or engine warning light. However, the same symptoms are often caused by a low gearbox oil level, a weak battery, a poor earth or a faulty sensor. To test a transmission control module, start by checking the battery and reading the fault codes with a diagnostic tool that can talk to the gearbox control unit, then check the power supply, the connector, the oil and the live data. Below we explain the symptoms, the diagnostic steps and what the most common fault codes mean.

Important: Depending on the ECU type and vehicle model, not all of the options listed below may be available.
To select the correct option for your vehicle and ECU, please contact us before purchasing:
contact@auto24parts.com
1. Locked
This option is intended for professional workshops with the required specialist equipment and technical knowledge.
The ECU has been removed from a vehicle intended for recycling and still contains the immobilizer data and other information from the previous vehicle. Before it can be used in another car, it must be unlocked and then programmed using specialist automotive diagnostic equipment.
2. Unlocked
Several preparation methods may be available. The possible options depend on the ECU type, vehicle model and immobilizer system. Please contact us before purchasing, as some preparation methods are not available for every ECU.
Our electronics specialists can prepare the ECU in one of the following ways:
a) ECU with PIN code (Car Pass)
The PIN code is supplied, but programming with a suitable diagnostic tool is still required. After installing the ECU, it must be reset using the supplied PIN code and then programmed to the vehicle’s immobilizer system.
b) VIRGIN ECU
The data from the previous vehicle is removed and the ECU is restored to a clean, factory-like state. After installation, it must be programmed to the vehicle using a compatible specialist diagnostic tool. Unless another preparation method is specified in the product description, this is the standard unlocking option for most of our ECUs.
c) Plug & Play – IMMO OFF
The immobilizer function is disabled in the ECU. After installation, the engine can start without additional immobilizer programming. Please note that the vehicle will no longer have an active immobilizer function, and an immobilizer warning light or fault code may remain, depending on the vehicle model.
d) Plug & Play – Automatic Programming
After installation, the ECU automatically learns and saves the required vehicle data. No additional programming is normally required.
e) Plug & Play – 1:1 Clone
The data from your original ECU is copied to another fully functional ECU. The cloned unit is then ready for installation without additional programming.
You must send us your original ECU so that we can transfer its data to the replacement unit.
The original ECU must have working communication with the vehicle, a diagnostic tool or our programming equipment. If the required data cannot be read, a complete 1:1 clone may not be possible.
3. Complete Plug & Play Set
A complete matched set containing the ECU, immobilizer components and all other parts required to start the vehicle without additional programming. All components supplied in the set must be installed in the vehicle.
Important:
Dispatch time depends on the selected option. If an unlocked or specially prepared version is ordered, the preparation service usually requires an additional 1–2 business days.

Will ECU 03C906024AB fit your Fabia 1.4?
The easiest way to check is by the VW number on your current unit's label – this one is a Magneti Marelli MY2 from a 1.4 petrol Fabia. We sell it used and fully working, locked or unlocked.
Engine Control Unit Skoda Fabia 1.4 Magneti Marelli MY2 03C906024AB
Magneti Marelli MY2 is a family of ECUs for petrol engines, and this unit was fitted to a Skoda Fabia 1.4. Unit 03C906024AB manages fuel injection and ignition, adjusting them to the engine's load and temperature. As well as the VW number, it carries the additional marking MY228406.
Numbers to compare
- 03C906024AB – VW/Skoda part number
- MY228406 – additional Magneti Marelli unit marking
- MY2 – ECU family
The two-letter AB suffix in the VW number distinguishes this version from other 03C906024 ECUs – it denotes specific software or hardware. So compare the whole number, letters included.
Signs of a unit failure
- no start despite a good power supply and fuel delivery,
- faults on several sensors at once, even though each of them is working,
- rough running both cold and warm,
- loss of communication with the ECU after water ingress or a voltage spike.
Start by reading the fault codes and measuring the voltage at the connector – the wiring, not the unit, is often to blame.
Choosing a version: locked or unlocked
Do you have your own equipment and experience with adaptation? Then the locked version will do – the ECU retains the previous car's data and immobiliser, and you carry out the unlocking, programming and adaptation yourself. If you would rather receive a ready unit, choose the unlocked version; we prepare it before dispatch, usually within 1–2 working days.
Please note: PIN / CAR PASS, Virgin, IMMO OFF, auto programming or cloning are not always an option – it depends on the part number, software version and immobiliser. Please ask us before ordering. All the options described: ECU preparation options.
Questions and answers
| Will unit 03C906024AB replace a 03C906024 ECU with a different suffix? |
|---|
| Not always. A different suffix means a different version, so send us the numbers from your ECU before you buy. |
| How long does it take to prepare the unlocked version? |
| Usually 1–2 working days before dispatch. We confirm the method beforehand, as it depends on the part number, software and immobiliser. |
| Will ECU 03C906024AB start the engine straight after fitting? |
| The locked version will not – it has to be unlocked and matched to the immobiliser. With the unlocked version, it depends on the preparation method agreed before purchase. |
| Is the unit new? |
| No – it is a fully working used ECU in good condition. You will find the warranty period in the product specification table. |
