The automatic transmission control unit (often designated as TCU or TCM) is a crucial electronic component responsible for smooth and trouble-free gear shifting. Its failure, most often caused by overheating, short circuits, or water damage, results in jerking, an inability to shift gears, or the vehicle entering limp mode. Purchasing a new module at an authorized dealership is a massive expense, which is why replacing it with a fully functional, used original is the most reasonable solution.

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.

Looking for a 03F906070D module for your Volkswagen Polo?
This used, working engine control unit has VW number 03F906070D and manufacturer number 5WP44629. It comes from a Volkswagen Polo with a petrol engine – confirm compatibility using the numbers on the label.
Engine Control Unit Volkswagen Polo 03F906070D 5WP44629
The VW number 03F906070D identifies this petrol engine ECU from a Volkswagen Polo. The label also carries the ECU manufacturer's number: 5WP44629. The module processes signals from the sensors and uses them to set the injection and ignition parameters.
Numbers on the label
- 03F906070D – Volkswagen (VW) part number
- 5WP44629 – ECU manufacturer's number
The letter D at the end of the number identifies the module version. As the engine size is not given, compare the whole number 03F906070D with your label.
Symptoms that may point to the ECU
- no spark or injection when cranking,
- the engine goes into limp mode on its own,
- hunting idle speed,
- stored internal ECU faults.
First check the fuses, power supply and earths – a loose earth produces very similar symptoms.
Preparation for fitting
You can choose between two versions. If your workshop has programming equipment, the locked version is enough – with the data and immobiliser from the donor car, to be unlocked and adapted by the workshop. We prepare the unlocked version in-house before the parcel is sent, which usually takes 1–2 working days.
The available method (PIN / CAR PASS code, Virgin, IMMO OFF, auto programming, cloning) depends on the part number, software version and type of immobiliser, so for the 03F906070D module we confirm it before you order. More information: ECU preparation options page.
Questions and answers
| Where can I find the number 03F906070D? |
|---|
| On the sticker on the ECU casing. Copy all the numbers from the label, including the letters at the end. |
| What should I send before ordering the unlocked version? |
| A photo of the label on your current ECU or all the numbers on it. Based on this, we will check which preparation methods are possible. |
| Can a workshop handle the locked version? |
| Yes, if it has equipment for programming and immobiliser adaptation. Without such equipment, it is better to choose the unlocked version. |
| Is the module working and covered by a warranty? |
| Yes – the ECU is used, working and in good condition. You will find the warranty period in the product features table. |
