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 GG ending in the number 03F906070GG mean?
The letters GG indicate a specific software or hardware version of the 03F906070 ECU. This unit, numbered 5WP44920, is used, in working order and fits a petrol Volkswagen with the same number.
Engine Control Unit Volkswagen 03F906070GG 5WP44920
The number 03F906070GG can be read in parts: the 906 070 section indicates an engine control unit, and the final letters GG its version. The unit comes from a petrol-engined Volkswagen and its label shows a second number, 5WP44920. It manages injection and ignition. It is used, in working order and in good condition.
Markings on the unit
- 03F906070GG – VW number with the ending GG
- 5WP44920 – number in the 5WP… format (Siemens VDO / Continental numbering)
When replacing the unit, the whole number counts – 03F906070 ECUs with a different pair of letters, e.g. GD or FB, are different versions. Also compare the second number on the label. If both match, you can be sure it is the same version of the unit.
Possible fault symptoms
- engine warning light and internal unit faults,
- no spark or injection even though the actuators are fine,
- rough idle,
- a problem after a voltage surge in the electrical system or water ingress.
First check the battery voltage and the condition of the unit's connector.
Locked or unlocked version?
The 03F906070GG ECU is available in two variants. In the locked version it keeps the data and immobiliser of the car it comes from – for workshops that will unlock, program and match it themselves. We prepare the unlocked version before dispatch, usually in 1–2 working days.
The availability of the methods – PIN / CAR PASS, Virgin, IMMO OFF, auto programming, clone – depends on the part number, software and immobiliser, so ask before you buy. Description: ECU preparation options.
