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.

How can I check whether the 03G906018CT ECU fits a Golf 2.0 TDI?
Compare VW number 03G906018CT and number 5WP45534AC with the label on your module. This is a used, fully working PPD1.2 ECU from a Golf 2.0 TDI, available locked or unlocked.
Engine Control Unit Volkswagen Golf 2.0 TDI PPD1.2 03G906018CT 5WP45534AC
The PPD1.2 designation refers to Simos PPD1.2 ECUs designed for diesel engines. In this unit from a Golf 2.0 TDI, the module carries VW number 03G906018CT, in the 03G 906 0xx format typical of engine control units. The second number, 5WP45534AC, belongs to the Siemens VDO / Continental numbering system.
Numbers of this module
- 03G906018CT – Volkswagen part number; CT denotes the version
- 5WP45534AC – Siemens VDO / Continental number
- PPD1.2 – ECU family
The car model and engine size alone are not enough for matching. What decides is the number 03G906018CT together with the final letters, which denote the software or hardware version. You will find the numbers on the label on the casing.
Symptoms of a faulty diesel ECU
- the engine cranks but will not fire,
- sudden stalling at low revs,
- difficulty connecting during diagnostics,
- limp mode and reduced power.
Before replacing it, check that the cause is not a damaged wiring loom, relay or earth – such faults produce very similar symptoms.
How we prepare the ECU
For the unlocked version we prepare the module before dispatch; this usually takes 1–2 working days. The possible method – PIN / CAR PASS, Virgin, IMMO OFF, auto programming or clone – depends on the part number, software and immobiliser, so please ask first what is available.
In the locked version the ECU holds the data and immobiliser from the previous vehicle; the workshop carries out the unlocking, programming and adaptation. Details: ECU options.
