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.

Used original engine control unit, number 7541459, inspected before sale. Matched by the numbers in the listing.
What does number 7541459 mean on BMW engine control units?
Engine control unit 7541459 is a used electronic module that manages engine operation. It is intended for BMW, and it is matched by the numbers in the listing, not by the car make alone. The listing does not state the car model or year, so we do not give them in the description and match the part by its numbers. The listing also gives the markings DME. They help tell the control unit versions apart, but the full part number is what decides compatibility.
Where to find the numbers on an engine control unit
The numbers as written in the listing and as a single string, the way catalogues list them:
- 7541459, car manufacturer's original number,
- 0261208388, control unit manufacturer's number.
Compare the numbers with the original control unit in your car, and if any of them differs, write to us before buying.
Control unit variant
This listing is for a control unit in the following variant(s): Locked / Unlocked. We describe the differences between the variants (locked, unlocked, Virgin, IMMO OFF, Plug and Play, clone, full set) on the ECU preparation options page. Before buying, send us the numbers from the label and we will confirm which variant is available for that number.
Symptoms of a faulty engine control unit
- the engine will not start although the starter motor works and there is fuel,
- the engine warning light comes on and does not go out,
- the diagnostic tester cannot connect to the control unit,

Questions and answers
| Where do I find number 7541459 on my control unit? |
