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 can I check whether the 03L906021A ECU will fit?
Compare VW number 03L906021A and Bosch number 0281019932 (on the sticker 0 281 019 932) with the label on your module. This is a used, working Bosch EDC17C64 for a diesel engine, offered locked or unlocked.
Engine Control Unit Volkswagen Crafter Bosch EDC17C64 03L906021A 0281019932
We offer this Bosch EDC17C64 ECU as a part for the Volkswagen Crafter, but when matching, the numbers matter most, not the model name. The number 03L906021A and Bosch number 0281019932 clearly identify the module version. EDC17 is the Bosch Electronic Diesel Control family of diesel engine ECUs.
How to identify this module
- 03L906021A – Volkswagen part number
- 0281019932 – Bosch number (0 281 019 932); the 0 281 prefix denotes a diesel ECU
- EDC17C64 – ECU type
The surest match is an identical VW number. The letter A at the end denotes the software or hardware version, and a module with a different letter may not work with your car.
Faults where it is worth checking the ECU
- no start despite a working starter motor,
- stored internal faults in the EDC17C64 module,
- communication problems during diagnostics,
- power restriction not caused by the sensors.
Before replacing it, rule out damage to the wiring loom, earths and the fuses supplying the ECU.
Choosing an option
We sell the 03L906021A ECU in two ways. The unlocked version is prepared before dispatch, usually within 1–2 working days. The locked version retains the data and immobiliser of the previous vehicle and is intended for workshops that will unlock, program and adapt it themselves.
For the unlocked version, the possible methods – PIN / CAR PASS, Virgin, IMMO OFF, auto programming or clone – depend on the number, software and immobiliser, so we agree them before purchase. See also the ECU preparation options.
