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.

Looking for a 7P0907401F ECU for a diesel Volkswagen?
This used, working Bosch EDC17CP44 module carries VW number 7P0907401F and Bosch number 0281017733 (label: 0 281 017 733). Choose the locked or unlocked version.
Engine Control Unit Volkswagen Bosch EDC17CP44 7P0907401F 0281017733
The number 7P0907401F looks different from the common 03L906… designations, so it is worth comparing it character by character. Behind this number is a Bosch EDC17CP44 – an ECU from the Electronic Diesel Control series that manages fuel injection in a diesel engine and monitors the sensors. You can establish the Volkswagen model from the numbers.
Numbers to compare
- 7P0907401F – VW number from the sticker on the casing
- 0281017733 – manufacturer's number, printed on the casing as 0 281 017 733
- EDC17CP44 – ECU variant from the EDC17 series
The letter F at the end of the VW number indicates the software or hardware version. Also check that the Bosch number on your ECU is 0 281 017 733.
Most common symptoms of a fault
- faults returning straight after being cleared, even though the wiring is sound,
- internal ECU faults stored in the fault memory,
- software cannot be read or written via the diagnostic port,
- no response after water damage, a voltage surge or failed programming.
Also check that the immobiliser or key is not to blame – in that case, replacing the ECU will not help.
Options for this ECU
We offer it locked or unlocked. If you choose the locked option, you receive the module with the previous vehicle's data, including the immobiliser – useful if your workshop will carry out the unlocking and adaptation itself. The unlocked option means we prepare the ECU before dispatch; as standard this takes 1–2 working days.
Before choosing the unlocked version, ask about the available methods. PIN / CAR PASS, Virgin, IMMO OFF, auto programming or cloning cannot be carried out for every number and software – much also depends on the immobiliser.
You can read more about the versions and preparation methods on the ECU preparation options page.
Questions and answers
| Are 0281017733 and 7P0907401F the same ECU? |
|---|
| Yes, they are two numbers of one module: 7P0907401F was assigned by Volkswagen, and 0281017733 by Bosch. |
| Is the EDC17CP44 marking alone enough for matching? |
| No. EDC17CP44 is a family covering many ECU versions; matching is decided by the VW number and the manufacturer's number. |
| Will the 7P0907401F ECU start the engine immediately after fitting? |
| Not the locked version – it has to be programmed and adapted to the immobiliser. With the unlocked version, it depends on the preparation method, which we agree before purchase. |
| What are the condition and warranty? |
| The ECU is used, working, in good condition. You will find the warranty period in the product features table. |
