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.

Where can you find the number 03C906057M on the ECU casing?
The VW/Skoda number 03C906057M is printed on the ECU sticker, usually next to the Bosch number 0 261 201 328. This used unit for the 1.6 petrol engine is fully working and available in two versions.
Engine Control Unit Skoda 1.6 Bosch 03C906057M 0261201328
A 1.6 engine that cranks but will not fire, or cuts out straight after starting – that is the typical situation in which a garage suspects the ECU. Unit 03C906057M, made by Bosch, manages fuel injection and ignition in the 1.6 petrol Skoda. The model is not specified, so match it using the numbers on the label.
Numbers to compare
- 03C906057M – VW/Skoda part number; the 03C 906 … format denotes an engine control unit
- 0261201328 – Bosch number, on the label 0 261 201 328 (the 0 261 series covers petrol ECUs)
The letter M at the end of the VW number indicates the software or hardware version. A unit with a different ending, for example 03C906057 with another letter, is not necessarily a replacement.
Typical signs of a fault
- the engine will not start or cuts out after a few seconds,
- one of the injectors or an ignition coil is not being triggered,
- no communication with the engine unit during diagnostics,
- problems that appeared after welding on the car or after a voltage spike.
First rule out the immobiliser and key and check the ECU's power supply – only then replace the unit.
How do we prepare the ECU?
You can choose the locked unit – with the donor car's data and immobiliser – if your garage will carry out the unlocking, programming and adaptation itself. The other option is the unlocked version, which we prepare before dispatch, usually within 1–2 working days.
What can be done (PIN / CAR PASS, Virgin, IMMO OFF, auto programming, cloning) depends on the part number, software version and immobiliser – not everything is possible with every ECU, so please ask before you buy. You will find a description on the ECU options page.
