A properly functioning ABS system is the foundation of road safety. Its main task is to prevent wheel lock-up during emergency braking, which allows the driver to maintain full control of the vehicle. The heart of this system is the electronic ABS pump controller. When it fails, the system stops working. A proper diagnosis of the problem allows you to avoid unnecessary costs and quickly restore brake efficiency.

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.

Which models use ECU 443907403G / Bosch 0280000739?
This ECU Engine controller is commonly listed for selected Volkswagen Passat and Volkswagen Jetta vehicles, and it is also found in some Seat Toledo 1.8 applications. The safest way to confirm compatibility is to match the numbers on your original unit.
You may see the same identifiers written differently, for example 443 907 403 G or Bosch 0 280 000 739—these are simply alternate label formats.
What do the numbers 443 907 403 G and 0 280 000 739 mean on the label?
443907403G is the vehicle manufacturer-style part number, while 0280000739 (often shown as 0 280 000 739) is the Bosch reference. Matching both references helps you choose the correct ECU version for your Volkswagen Passat or Jetta.
Even similar-looking ECUs can differ in configuration or software, so the exact combination 443907403G + 0280000739 matters.
What does the engine ECU actually do in a Passat/Jetta 1.8?
The engine ECU controls key engine functions during driving. It processes sensor data and manages items such as fuel delivery and ignition timing to keep the engine running smoothly.
That is why choosing the correct ECU by number—such as 443907403G and Bosch 0280000739—is essential for proper operation.
Typical symptoms of a faulty ECU (443907403G) in Volkswagen Passat/Jetta
A failing ECU can cause hard starting, rough running, power loss, stalling, or a Check Engine light. In some cases, diagnostics may show inconsistent fault codes or communication issues.
This unit is offered as a tested product with warranty and fast shipping to help you replace the ECU with more confidence.
Does Bosch ECU 0280000739 require coding/adaptation after installation?
Depending on the vehicle version and its electronic setup, an ECU replacement may require adaptation or coding after installation. This is most common when the ECU must be matched to other modules in the vehicle.
Exact part number matching (443907403G and 0280000739) makes installation and later operation much easier.
