The engine control unit (often referred to as ECU or ECM) is the most important electronic module in every modern vehicle. It acts as the main computer managing the operation of the power unit, analyzing signals from numerous sensors in real-time. It is responsible for precise fuel dosing, ignition timing, boost pressure, and the operation of exhaust gas treatment systems. When this crucial component fails, normal operation of the car becomes impossible. When faced with electronic problems, many drivers consider complicated diagnostics, circuit testing, and attempting to repair integrated circuits. In practice, the fastest, safest, and most cost-effective solution is to replace the damaged component with a fully functional, original used part from the aftermarket.

Attention : Depending on the type of engine controller and car model, not every variant from the list below is available.
To choose the correct variant for your car and model engine controller please contact with us :
1.Locked: This variant is intended for workshops that have specialized equipment and knowledge.
Engine computer removed from a car intended for recycling with data saved from the previous car and immobilizer. To use this controller it is required to unlock it and then perform the programming procedure. For this purpose, it is necessary to use specialized diagnostic equipment for electronics.
2.Unlocked: There are many variants of the possible unlock device , so please contact us before purchasing because, depending on the type and model of the car or controller itself make some unlocking options not possible.
The controller can be prepared for assembly by our electronics in various ways: the list below
a) ECU with read PIN code (CAR PASS) - Required programming by diagnostic device. After the assmbly of the ecu to the car you need to reset that controller by typing in the pin code, and then performing the procedure of programming the immobilizer to your car
b) Cleaned Ecu out of the data of the previus car (VIRGIN). The ECU is reset to factory settings, prepared as clean. After installation in the car, it requires programming by using a specialized diagnostic device (STANDARD Unlocking of most of our ECUs if not specified the unlocking form)
c)Plug & Play (IMMO OFF) - excluded immobilizer, it has removed the safety codes from the ecu. Once its connected ecu to the car the engine runs and it does not require any programming, but it does not have the immobilizer function. - No need additional programming
d) Plug & Play (AUTO PROGRAMMING) - after assembly the ecu in the car, ECU will automatically program itself to your car. Does not require any programming
e) Plug & Play (CLON) - a cloned controller prepared for installation in a car without the need for programming. This device is copied 1 to 1 from the old device and the data is transferred to another properly working computer by our electrician service technician
Have to send us the damaged driver from which the data will be transferred to another, properly working computer.
Broken ecu HAS to have working communication with the car or diagnostic device , without proper communication Security code cant be cloned.
3.Complete: Plug & Play complete set ecu with immobilizer and all elements needed to start the vehicle without need for additional programming. Have to replace all the elements sent by us in your car.
Attention :
Delivery time depends on the selected variant: if the unlocked version is selected,
the unlocking service takes an additional time of around 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
