A faulty transmission control module (TCM) most often causes limp mode with the gearbox stuck in one gear, harsh jolts when you select D or R, erratic gear changes, flashing PRND letters and a gearbox or engine warning light. However, the same symptoms are often caused by a low gearbox oil level, a weak battery, a poor earth or a faulty sensor. To test a transmission control module, start by checking the battery and reading the fault codes with a diagnostic tool that can talk to the gearbox control unit, then check the power supply, the connector, the oil and the live data. Below we explain the symptoms, the diagnostic steps and what the most common fault codes mean.

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.

How do you recognise the 03L906012D ECU from a Volkswagen Crafter?
On the label you will find VW number 03L906012D, Bosch number 0 281 017 663 and the marking EDC17C54-3.39. We sell this used, working module locked or unlocked.
Engine Control Unit Volkswagen Crafter Bosch EDC17C54-3.39 03L906012D 0281017663
The EDC17 family consists of Bosch Electronic Diesel Control ECUs, and the EDC17C54-3.39 variant was used in the Volkswagen Crafter, among others. The module with number 03L906012D oversees common rail injection, fuel pressure and boost. When the ECU stops working, the engine usually will not start or runs in limp mode, and the diagnostic tool cannot see the module.
Numbers and markings
- 03L906012D – Volkswagen part number; the letter D is the version designation
- 0281017663 – Bosch number, as on the label: 0 281 017 663
- EDC17C54-3.39 – Bosch EDC17 ECU type
The same EDC17C54 family appears under many VW numbers. Compatibility is decided by the number 03L906012D including its final letter, not by the type designation alone.
Symptoms that may point to the ECU
- the engine will not fire, yet the pump and injectors are working,
- the engine warning light stays on and there are internal ECU faults in the memory,
- no connection with the module via the diagnostic port,
- the engine cutting out intermittently while driving.
Before deciding to replace it, measure the power supply and earths directly at the module connector.
Locked version or version prepared by us
If your workshop has programming equipment, choose the locked option. The ECU will arrive with the data and immobiliser of the previous car, and the workshop will unlock, program and adapt it itself.
We prepare the unlocked option before dispatch, mostly within 1–2 working days. Not every method is available for every ECU – PIN / CAR PASS, Virgin, IMMO OFF, auto programming or clone depend on the number, software and immobiliser. Ask about this before buying.
You will find a full description on the ECU preparation options page.
Questions and answers
| Will an EDC17C54-3.39 with a different VW number also fit? |
|---|
| Not necessarily. Compare the number 03L906012D – the family designation alone is not enough. |
| How long will I wait for the unlocked version? |
| Preparation usually takes 1–2 working days before dispatch. |
| Will the engine start after fitting the locked version? |
| No, it must first be unlocked, programmed and adapted to the immobiliser. |
| What condition is the ECU in? |
| Used, working, in good condition. You will find the warranty period in the product features table. |
Send a photo of the label to contact@auto24parts.com and we will check compatibility with your module.
