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 03L906018GJ on a Volkswagen Jetta ECU mean?
It is the Volkswagen part number under which the Bosch diesel engine ECU numbered 0281017286 is listed. The GJ suffix indicates a specific version of the module, so compare the full number when matching.
Engine Control Unit Volkswagen Jetta Bosch EDC17CP46 03L906018GJ 0281017286
The designation of this module from a Volkswagen Jetta contains three pieces of information: VW number 03L906018GJ, Bosch number 0281017286 and the EDC17CP46 family. EDC stands for Electronic Diesel Control, Bosch's line of ECUs for diesel engines. The computer manages injection, boost and the engine ancillaries based on sensor readings.
How to identify this ECU
- 03L906018GJ – Volkswagen part number – the main number to compare
- 0281017286 – Bosch number, written on the label as 0 281 017 286
- EDC17CP46 – ECU family designation given in the product name
The letters GJ at the end of the VW number are not decoration – they define the software or hardware version. A 03L906018 ECU with a different suffix may have different data, so compare the full number and the Bosch number.
When to suspect the engine ECU
- the engine will not fire although the starter and fuel supply are fine,
- stored communication errors with the engine module,
- sudden loss of power with working sensors and injectors,
- damage after moisture, a voltage spike or interrupted programming.
Check the connector, fuses and earths first – an oxidised pin can cause similar symptoms.
Versions to choose from
You can choose a locked ECU, with the data and immobiliser from the previous Jetta, intended for workshops that will handle the unlocking, programming and adaptation themselves. The other option is the unlocked version, which we prepare before dispatch, usually within 1–2 working days.
Not every preparation method – PIN / CAR PASS, Virgin, IMMO OFF, auto programming or clone – will work on every ECU. The part number, software and immobiliser decide, so please ask before you buy. Description of the options: ECU options page.
