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 does 047906030N / 5WP432905 differ from version 5WP432602?
The VW number is the same; the Siemens number differs, which may indicate a different build of the unit. This one, from a Felicia 1.3, is labelled 5WP4329 05 and is used and fully working.
Engine Control Unit Skoda Felicia 1.3 Siemens 047906030N 5WP432905
The Siemens number 5WP432905 is the feature that distinguishes this ECU from other 047906030N units for the Felicia 1.3. It comes from a petrol Skoda Felicia 1.3 and is responsible for fuel injection and ignition. On the label, the Siemens number is written with a space: 5WP4329 05.
Numbers on the label
- 047906030N – VW/Skoda part number
- 5WP432905 – Siemens number (as on the label 5WP4329 05)
If your Felicia has a 047906030N ECU with a different Siemens number, please ask us about compatibility before you buy. The letter N identifies the software or hardware version, and the 5WP number specifies the build more precisely.
How to recognise a faulty ECU
- the engine cuts out while driving for no obvious reason,
- misfiring on one or more cylinders despite a working ignition system,
- running in limp mode and poor throttle response,
- problems that appeared after welding, a jump start or water ingress.
First check the unit's earths, connectors and power supply, and only then the ECU itself.
Which version should you order?
There are two versions to choose from. With the unlocked one, we prepare the unit for your car before dispatch – usually within 1–2 working days, using a method chosen to suit the part number, software and immobiliser. PIN / CAR PASS, Virgin, IMMO OFF, auto programming or cloning are possible, but not always all of them, so please ask before you buy.
The locked one retains the previous car's data and immobiliser. It is an option for garages that handle unlocking, programming and adaptation themselves. We explain how it works on the ECU options page.
Questions and answers
| My ECU has the number 5WP432602 – will this one fit? |
|---|
| The VW number 047906030N is the same, but the Siemens numbers differ. We will confirm compatibility once we have seen a photo of the label. |
| Can I fit the locked version myself? |
| Only if you have the equipment for unlocking, programming and adaptation. Without it, you are better off choosing the unlocked version. |
| What should I send before ordering the unlocked version? |
| A photo of the label on your current ECU, or all the numbers from it. On that basis, we will establish which preparation method is possible. |
| What warranty does this unit have? |
| You will find the warranty period in the product specification table. The ECU is used, fully working and in good condition. |
We will help you choose the right version – send the ECU numbers to contact@auto24parts.com.
