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 ECU 045906019BB fits an Ibiza or Cordoba?
Compare the sticker on your ECU with ours: VW number 045906019BB and Bosch number 0281011074 (0 281 011 074). This used, working diesel module comes from a Seat Ibiza, Seat Cordoba or Volkswagen.
Engine Control Unit Volkswagen, Seat Ibiza, Seat Cordoba Bosch 045906019BB 0281011074
According to our records, Bosch module 045906019BB was used in the Seat Ibiza, the Seat Cordoba and Volkswagen vehicles. The ECU manages the diesel engine: injection, turbo boost and starting. When buying a replacement, what counts is that the numbers on the label match.
Numbers to check
- 045906019BB – Volkswagen part number
- 0281011074 – Bosch number from the diesel ECU series, on the label 0 281 011 074
When choosing a replacement, go by the number, not just the vehicle model. The BB suffix is the software and hardware version, so a module with a different letter may not work properly.
Typical symptoms
- the diesel turns over but will not fire up,
- the ECU does not respond when the tester is connected,
- loss of power and the engine warning light on with no other faults,
- module failure after moisture or a short circuit in the wiring.
The first step is to check the ECU power supply and earths – a wiring fault is sometimes mistaken for a damaged module.
Preparation options
ECU 045906019BB can be bought locked, i.e. with the data and immobiliser of the vehicle it came from – a solution for workshops that do the unlocking and adaptation themselves. The alternative is the unlocked version, which we prepare before dispatch, usually within 1–2 working days.
Not every method can be used with every ECU: PIN / CAR PASS, Virgin, IMMO OFF, auto programming or cloning. The number, software and immobiliser all play a part, so please ask before buying. Full description: ECU preparation options.
