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 03F906070A on a Golf ECU mean?
It is the VW part number which, together with manufacturer number 5WP44602, identifies this petrol engine ECU. The unit is used and working; you can order it locked or unlocked.
Engine Control Unit Volkswagen Golf 03F906070A 5WP44602
The number 03F906070A ends in a single letter – A – and it is this suffix that distinguishes it from other ECUs with a similar base number. This used, working petrol engine ECU comes from a Volkswagen Golf and also carries manufacturer number 5WP44602. It controls injection and ignition based on sensor signals. We do not state the engine capacity, so base your choice on the numbers on the label.
Numbers on the label
- 03F906070A – VW part number, group 906 denotes an engine control unit
- 5WP44602 – ECU manufacturer number
Many versions with different final letters are found with this base number. The letter denotes the software and hardware version, so compare 03F906070A in full, together with the 5WP number.
When to suspect the engine control unit?
- the engine will not start despite a working power and fuel supply,
- the diagnostic tool cannot see the unit,
- the engine warning light is on and an ECU fault is stored in the memory,
- the engine runs unevenly with no fault in the coils and sensors.
Before ordering a replacement, check the fuses and earth leads.
Locked or unlocked – the differences
The main difference concerns the data in the memory. A locked ECU holds the data and immobiliser of the previous car – it is bought by workshops that will unlock, program and match the unit themselves. We prepare the unlocked unit before dispatch, usually within 1–2 working days.
The method (PIN / CAR PASS, Virgin, IMMO OFF, auto programming, clone) depends on the part number, software and immobiliser; not every one will be possible with 03F906070A. Ask before you buy. Description: Engine control unit (ECU) variants.
