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.

Will the EDC16U34 ECU numbered 03G906021AB fit your Passat 2.0 TDI?
It will if your module has the same VW number 03G906021AB and Bosch number 0281012119. The EDC16U34 family alone is not enough – there are many versions within it.
Engine Control Unit Volkswagen Passat 2.0 TDI Bosch EDC16U34 03G906021AB 0281012119
Bosch EDC16U34 is the Electronic Diesel Control ECU family to which this module for the Volkswagen Passat 2.0 TDI belongs. The specific version is defined by VW number 03G906021AB and Bosch number 0281012119. The ECU manages fuel injection and boost based on sensor signals.
Numbers and designations
- 03G906021AB – Volkswagen part number with suffix AB
- 0281012119 – Bosch number, shown on the label as 0 281 012 119
- EDC16U34 – Bosch ECU family
Many EDC16U34 ECUs look identical but differ in their software. That is why the letters AB at the end of the VW number matter – they denote the software or hardware version.
Typical fault symptoms
- the Passat 2.0 TDI will not start although the starter motor works,
- the engine goes into limp mode with no sensor fault,
- the diagnostic tool cannot connect to the engine ECU,
- failure after water ingress, a voltage spike or failed programming.
Before ordering the module, rule out damage to the power supply, earths and the wiring loom at the connector.
Locked or unlocked – which to choose
A locked module holds the data and immobiliser of the donor Passat. It is ordered by workshops that will unlock, program and adapt it themselves. We prepare an unlocked module before dispatch – usually within 1–2 working days.
For EDC16U34 ECUs the various methods (PIN / CAR PASS, Virgin, IMMO OFF, auto programming, clone) may or may not be available – it depends on the part number, software and immobiliser. Please ask before you buy. Description: engine control unit options.
