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.

Does the 038906012HC unit fit a 2004 Octavia 1.9 TDI?
It does if the label on your ECU shows the VW number 038906012HC or the Bosch number 0 281 011 311. This unit comes from a 2004 Octavia 1.9 TDI; it is used and fully working.
Engine Control Unit Skoda Octavia 1.9 TDI Bosch 038906012HC 0281011311
This Bosch engine control unit was removed from a 2004 Skoda Octavia 1.9 TDI. It has the VW number 038906012HC and the Bosch number 0281011311 – the 0 281 series covers diesel engine control units. The unit controls fuel injection and works with the immobiliser. If your Octavia cuts out, will not start or the diagnostic tool cannot see the ECU, comparing the numbers is a good place to start.
Markings on the casing
- 038906012HC – VW/Skoda part number
- 0281011311 – Bosch number (shown on the label as 0 281 011 311)
The car's year helps, but it does not guarantee compatibility. The full number decides – the HC suffix indicates a specific software or hardware version.
How can you tell the ECU has failed?
- the engine has cut out and will not restart despite repeated attempts,
- the engine warning light stays on permanently,
- loss of communication with the diagnostic tool,
- limp mode even though the sensors are working.
Before replacing the ECU, check the fuses, earths and wiring loom – a damaged connector produces similar symptoms.
Two options to choose from
You can buy this unit in one of two versions:
- locked – with the previous vehicle's data and immobiliser; for workshops that will unlock, program and match it themselves,
- unlocked – prepared by us before dispatch, usually within 1–2 working days.
Whether PIN / CAR PASS, Virgin, IMMO OFF, auto programming or cloning will work in your case depends on the part number, software and immobiliser – ask before you buy. More: ECU preparation options.
