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 036906032B ECU for an Octavia 1.4?
This is a used, fully working Bosch unit, number 0261207124, from a petrol Skoda Octavia 1.4. Choose the locked version for a garage, or the unlocked one.
Engine Control Unit Skoda Octavia 1.4 Bosch 036906032B 0261207124
The engine control unit in the Octavia 1.4 determines the fuel quantity, ignition timing and idle speed – without a working unit, the engine will not run. This one is a Bosch unit, number 0261207124; the 0 261 prefix denotes an ECU for a petrol engine. The VW/Skoda number of the unit is 036906032B.
Numbers from the label
- 036906032B – VW/Skoda part number
- 0261207124 – Bosch number (0 261 207 124)
The letter B at the end of the VW number denotes a specific software or hardware version. When matching, compare both numbers – the 1.4 engine size alone is not enough.
Symptoms of unit failure
- the starter turns but the engine will not catch,
- sudden stalling once warmed up,
- no control of the fuel pump or cooling fan,
- the ECU does not respond to the diagnostic tester.
Also check the immobiliser and the key, as a start inhibit is often mistaken for an ECU fault.
Choosing a variant: locked or unlocked
Do you have your own equipment and experience with adaptation? Then the locked variant is enough – the ECU keeps the data and immobiliser of the previous car, and you carry out the unlocking, programming and adaptation yourself. If you would rather receive a ready-to-use unit, choose the unlocked variant; we prepare it before dispatch, most often within 1–2 working days.
Please note: PIN / CAR PASS, Virgin, IMMO OFF, auto-programming or clone are not always an option – it depends on the part number, software version and immobiliser. Ask us before ordering. Description of all options: engine control unit (ECU) variants.

| Will the 036906032B ECU start the engine straight after fitting? |
| Not in the locked version – it has to be unlocked and matched to the immobiliser. With the unlocked version, it depends on the preparation method agreed before purchase. |
| How long does it take to prepare the unlocked version? |
| Usually 1–2 working days before dispatch. We confirm the method beforehand, as it depends on the part number, software and immobiliser. |
