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:

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.

Will the 05L907309AH ECU fit your Volkswagen Crafter?
Compatibility is determined by the VW number 05L907309AH and the Bosch number 0281040142 (written on the label as 0 281 040 142). We offer this used, fully working Bosch MD1CS104 module in a locked or unlocked version.
Engine Control Unit Volkswagen Crafter Bosch MD1CS104 05L907309AH 0281040142
MD1CS104 is the Bosch ECU type designation, and the Bosch number 0281040142 with the 0 281 prefix indicates a diesel engine module. We list this part as an ECU for the Volkswagen Crafter, but before buying always compare the number 05L907309AH with the label on your own module – that is what decides compatibility.
Numbers to check
- 05L907309AH – Volkswagen part number; the AH suffix denotes the version
- 0281040142 – Bosch number (0 281 040 142)
- MD1CS104 – Bosch ECU type
You will find the numbers on the label on the casing. If your ECU has a different letter after 05L907309, get in touch before ordering.
When to suspect a faulty module
- the engine will not start although power supply and fuel are fine,
- no communication with the engine computer,
- numerous fault codes in other modules about lost signal from the ECU,
- failure after welding work, water ingress or a voltage spike.
First rule out damaged wiring and fuses – that is cheaper than replacing the ECU.
Unlocked or locked?
The unlocked version is an ECU we prepare before dispatch; this usually takes 1–2 working days. Not every method (PIN / CAR PASS, Virgin, IMMO OFF, auto programming, clone) can be carried out on every module – it depends on the part number, software and immobiliser, so please ask us before you buy.
The locked version holds the data and immobiliser from the previous vehicle. It is bought by workshops that unlock, program and adapt ECUs themselves. All options: engine control unit options page.
