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 do I check whether ECU 03F906070ES will fit your Golf?
Compare two numbers from the label: VW number 03F906070ES and manufacturer number 5WP44755. If they match your unit, you can order this used, working ECU – locked or unlocked.
Engine Control Unit Volkswagen Golf 03F906070ES 5WP44755
This petrol engine ECU has a VW number ending in the letters ES – 03F906070ES – and manufacturer number 5WP44755. It comes from a Volkswagen Golf, where it managed injection and ignition using signals from the engine sensors. It is used, working and in good condition, and we check that the numbers on the label match before dispatch.
Numbers on the label
- 03F906070ES – VW part number
- 5WP44755 – ECU manufacturer number
The letters ES at the end of the VW number denote the software and hardware version, so it matters that they match. Do not treat the model and capacity as the deciding factor – it is the numbers that count.
When can the ECU be the cause of problems?
- the engine cranks on the starter but will not start,
- the diagnostic tool cannot connect to the ECU,
- the car stalls or goes into limp mode with no sensor faults,
- the unit has been damaged by water or a voltage surge.
First check the main power relay, fuses and wiring loom condition – a damaged wire can produce exactly the same symptoms as a failure of the unit itself.
How do we sell this ECU?
We offer unit 03F906070ES locked or unlocked. In the first case it holds the data and immobiliser of the previous car – it is intended for workshops that will unlock, program and match it themselves. In the second, we prepare it before dispatch, which usually takes 1–2 working days.
Not every method will be possible: PIN / CAR PASS, Virgin, IMMO OFF, auto programming or clone depend on the part number, software and immobiliser. So please ask before you buy. You will find a description of the options on the Engine control unit (ECU) variants page.
