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.

The control unit's role in the engine
The module contains memory holding the software and engine data, and in some cars the immobiliser data as well. That is why the software version matters as well as the part number. The module stores fault codes which, once diagnostic equipment is connected, help to establish whether the sensors, the wiring or the control unit itself is at fault.
How to match this part
We also stock other control units for this model and engine, with different numbers. Match the part by the number on the module, not by the model alone. The numbers on the module appear in two forms: split into groups or as one continuous string. We give both to make the part easier to find.
When the control unit needs replacing
- no power to the injectors or ignition coils,
- memory and checksum errors,
- the engine will not start even though the battery is in good order,
- the control unit reports an internal fault.
Note down the stored fault codes before removing the unit, as after the replacement they will help you judge whether the problem has been solved.
Locked or unlocked version?
With the unlocked variant, we prepare the module ourselves before dispatch - this usually takes 1-2 working days. In the locked variant, the control unit still holds the security coding and data of the car it came from, so it needs to be unlocked and programmed. Not all unlocking methods - PIN / CAR PASS, Virgin, IMMO OFF, auto programming or clone - are available for every number, as a lot depends on the software and the immobiliser. You will find the details here: locked vs unlocked engine control units. We are also happy to answer any questions before you buy.
