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 5WP42944AA on the 03L906023KB ECU mean?
5WP42944AA is the manufacturer's number – the 5WP… numbering belongs to Siemens VDO / Continental. On the Volkswagen side, the module carries number 03L906023KB, which is the basis for matching.
Engine Control Unit Volkswagen Continental 03L906023KB 5WP42944AA
Not every diesel ECU in a Volkswagen is made by Bosch – this unit was manufactured by Continental. That is shown by the number 5WP42944AA, printed on the label as 5WP42944 AA. The VW part number is 03L906023KB. The module manages fuel injection, starting and the running of the diesel engine, and stores fault codes in its memory. Condition: used, working, good.
Numbers to compare
- 03L906023KB – VW part number
- 5WP42944AA – Continental manufacturer's number (on the label: 5WP42944 AA)
The letters KB at the end of the VW number identify the software or hardware version. A module from the 03L906023 series with a different suffix is not necessarily a replacement, so always compare the full number.
Signs of a faulty ECU
- no start even though the fuel supply system is working,
- limp mode and restricted power,
- no connection with the diagnostic tool or internal module faults,
- the engine cutting out while driving.
Start by checking the connector, earths and power supply – in many cases that is enough to find the cause.
Available ECU versions
We dispatch the locked version with the data and immobiliser of the car it came from. This option is for workshops that unlock, program and adapt the Continental module themselves. The unlocked version is prepared before dispatch – this usually takes 1–2 working days.
The PIN / CAR PASS, Virgin, IMMO OFF, auto programming and clone methods are not available for every ECU; it depends on the number, software and immobiliser. Ask before buying. All the options are described here: ECU preparation options.
Questions and answers
| Can a Bosch ECU replace this Continental module? |
|---|
| Do not assume so. Match it by VW number 03L906023KB and the manufacturer's number. |
| Are 5WP42944 AA and 5WP42944AA the same number? |
| Yes, on the label the AA suffix is separated by a space. |
| Which version should I choose? |
| If you do not have a workshop that can program the ECU itself, choose the unlocked version – we will prepare it before dispatch. |
| What condition is the module in? |
| Used, working, in good condition. You will find the warranty period in the product features table. |
