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.

What does the number 441.0.4046-024.6 on the Felicia 1.3 ECU mean?
It is the Skoda part number in the format used on older Felicias; it is sometimes also given without dots as 441040460246. The unit carries Bosch number 0261203544 and is used and fully working.
Engine Control Unit Skoda Felicia 1.3 Bosch 441.0.4046-024.6 0261203544
Bosch 0261203544 is a petrol engine control unit – the start of the number, 0 261, already tells you that. It comes from a Skoda Felicia 1.3, where Skoda gave it its own number, 441.0.4046-024.6. It controls fuel injection and ignition, and without it the engine will not start.
Numbers to compare
- 0261203544 – Bosch number (shown on the label as 0 261 203 544)
- 441.0.4046-024.6 – Skoda part number
- 441040460246 – the same Skoda number written without separators
A Skoda number in this format has no version letter of the kind typical of VW, so compare it in full, including the digits after the hyphen. At the same time, check that the label on your unit shows Bosch number 0261203544.
What to check before replacing it
- the engine cranks but will not fire, and the fuel pump does not run,
- hunting idle or hesitation when pulling away,
- a stored internal ECU fault code,
- noticeably higher fuel consumption with no sensor fault.
Before you replace the ECU, check the fuses, the main relay and the engine earth connections.
Preparation before dispatch
We send this ECU in the variant you choose. We prepare the unlocked unit before dispatch – usually within 1–2 working days. The locked unit is left with the data and immobiliser of the previous car; this option is for garages that unlock, program and adapt ECUs themselves.
Not every method – PIN / CAR PASS, Virgin, IMMO OFF, auto-programming, clone – will work with every unit, as it depends on the part number, software and immobiliser. Please ask before you buy. Details: engine control unit variants.
