Individual variants may differ in price
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:

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.

The ECU engine controller 03L906023PG and 5WP42941AA is a proven part that ensures proper and stable engine operation in Volkswagen vehicles.
The Ecu engine controller with part numbers 03L906023PG and 5WP42941AA is responsible for managing engine operation in Volkswagen vehicles. It controls fuel injection, cooperates with sensors and regulates combustion parameters, ensuring smooth, efficient and manufacturer-compliant engine performance.
This Ecu engine controller was installed in selected Volkswagen models with diesel engines. Exact compatibility depends on the production year and engine version, so before purchase it is recommended to compare part numbers or contact us for VIN verification.
The most reliable method is checking the numbers on your current unit. If the housing shows 03L906023PG or 5WP42941AA, compatibility is confirmed. You may also send us a photo of your old Ecu engine controller for verification.
The best results come from entering the full part number, e.g. 03L906023PG. It is also worth checking alternative formats such as 5WP42941AA, as different catalogues may use different numbering formats.
In most cases, adaptation, programming or cloning of the Ecu engine controller is required after installation to ensure correct cooperation with the immobilizer and vehicle electronics. This is a standard procedure when replacing ECU units in Volkswagen cars.
In our store we offer two variants of the Ecu engine controller: a locked version and a virgin (logged-out) version. Before choosing, please read the variant descriptions carefully to select the best option for your vehicle and planned installation.
If the Ecu engine controller 03L906023PG / 5WP42941AA is in stock, shipping usually takes place within 24–48 hours. The current processing time is always listed in the product description.
In such a case, contact us with the part number and vehicle model. We will help you select the correct Ecu engine controller or propose a compatible solution.
