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 03C906056EB ECU fit an Octavia 1.6 FSI?
It comes from a 2006 Octavia 1.6 FSI, but please confirm compatibility using the VW number and the Bosch number 0 261 S02 380. The unit is used and fully working.
Engine Control Unit Skoda Octavia 1.6 FSI Bosch 03C906056EB 0261S02380
FSI stands for a petrol engine with direct injection – and this Bosch ECU was matched to just such an engine in a 2006 Skoda Octavia 1.6. Unit 03C906056EB controls fuel injection, ignition and engine operation under varying load. The Bosch number of this unit is 0261S02380.
Numbers to compare
- 03C906056EB – VW/Skoda part number
- 0261S02380 – Bosch number (0 261 S02 380)
The suffix EB in the VW number identifies the software or hardware version. 03C906056 units with a different suffix may not fit, so compare the full number.
Typical fault symptoms
- the engine cuts out while driving for no obvious reason,
- misfiring on one or more cylinders even though the ignition system is fine,
- running in limp mode and poor throttle response,
- problems that appeared after welding, jump-starting or water ingress.
Check the earths, connectors and the unit's power supply first, and only then the ECU itself.
ECU supply variants
We prepare the unlocked ECU before dispatch; this usually takes 1–2 working days. The locked version is left unchanged – it contains the data and immobiliser of the vehicle it was removed from and is intended for garages that carry out unlocking, programming and adaptation themselves.
Which preparation method can be used (PIN / CAR PASS code, Virgin, IMMO OFF, auto-programming, clone) depends on the part number, software and immobiliser. Before buying, ask what is possible with this unit. Description: Engine control unit variants.
