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.

What does the number 443907403G on an engine ECU mean?
It is the Volkswagen part number under which Bosch supplied the 0280000739 ECU (0 280 000 739 on the label). According to our data, the module was used in the Volkswagen Passat, Volkswagen Jetta and Seat Toledo with a 1.8 petrol engine.

The same engine ECU can fit several cars from the group – as is the case with the 443907403G module, which according to our data was used in the Volkswagen Passat, Volkswagen Jetta and Seat Toledo with a 1.8 petrol engine. The manufacturer is Bosch, and its designation is 0280000739. Starting and smooth running of the engine depend on the ECU working properly.
Markings on the casing
- 443907403G – Volkswagen (VW) part number
- 0280000739 – Bosch number, written on the label as 0 280 000 739
The final letter G distinguishes this module from other versions numbered 443907403. So whatever the make of car, compare the complete number from the label.
Symptoms that may point to the ECU
- the engine will not start, even though the starter turns and fuel is getting through,
- the engine warning light is on and the memory holds injection or ignition faults with no component failure,
- the diagnostic tester cannot connect to the ECU,
- the engine stalls or idles unevenly.
The first step should be reading the fault codes and checking the wiring – many faults lie in the cables, not in the module.
Locked or unlocked – which to choose?
The 443907403G ECU can be ordered locked or unlocked. The locked version holds the data and immobiliser of the car it came from – your workshop then carries out the unlocking, programming and adaptation.
With the unlocked version we take care of the preparation and do it before dispatch (usually 1–2 working days). Bear in mind that whether a PIN / CAR PASS, Virgin version, IMMO OFF, auto programming or a clone can be used depends on the number, software and immobiliser – write to us before buying.
