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.

Will ECU 441.0.4046-028.6 / 0261203964 fit your Skoda?
It will if your current ECU carries the same Skoda number 441.0.4046-028.6 and the Bosch number 0 261 203 964. This unit for a petrol engine is used, fully working and available in a locked or unlocked version.
Engine Control Unit Skoda Bosch 441.0.4046-028.6 0261203964
When the car stops responding to the key and diagnostics cannot see the engine unit, replacing the ECU is sometimes the only solution. This Bosch unit with the Skoda number 441.0.4046-028.6 runs a petrol engine – it controls injection and ignition. We do not give the model or engine size here: compatibility follows from the numbers on the label.
Numbers on the sticker
- 441.0.4046-028.6 – Skoda part number in the older format
- 441040460286 – the same number written without dots or a hyphen
- 0261203964 – Bosch number (0 261 203 964), from the petrol ECU series
The -028.6 ending is crucial: ECUs in the 441.0.4046 series with a different ending have different software. Also make sure the Bosch number matches.
Symptoms worth knowing
- no communication with the engine ECU,
- the engine cranks but will not fire, even though fuel is reaching the injectors,
- random cutting out while driving,
- visible signs of overheating or corrosion on the circuit board once the casing is opened.
Check the ECU power relay and fuses first – their failure looks similar.
Which version should you order?
We supply the ECU in two ways. The unlocked unit is prepared by us before dispatch (usually 1–2 working days). The locked unit is sent with the data and immobiliser of the car it came from – it is chosen by garages that will unlock, program and adapt it themselves.
The PIN / CAR PASS, Virgin, IMMO OFF, auto programming and cloning options are not universal; what can be done depends on the part number, software and immobiliser. Please contact us before you buy and have a look at the ECU options page.
