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 03G906016GS ECU fit a Superb 1.9 TDI?
Yes, provided your Superb has an ECU with an identical VW number – 03G906016GS. This used Bosch unit (0281012552) comes from a 2005 car with the 1.9 TDI engine and is fully working.
Engine Control Unit Skoda Superb 1.9 TDI Bosch 03G906016GS 0281012552
This unit worked in a Superb with the 1.9 TDI engine – a 2005 car. The Bosch 03G906016GS ECU reads sensor data, sets the fuel quantity and injection timing, controls the turbocharger and takes part in immobiliser authorisation. Bosch number: 0 281 012 552. Without a working unit, the engine will not fire even with a good starter and fuel supply.
Numbers to compare
- 03G906016GS – VW/Skoda number,
- 0281012552 – Bosch number; shown on the label as 0 281 012 552.
The letters GS at the end of the VW number denote a specific version. If your unit has a 03G906016 number with a different suffix, ask us before you order.
What might indicate a fault?
- the engine will not start or cuts out,
- the car loses power and goes into limp mode,
- ECU faults keep coming back despite being cleared,
- no communication during diagnostics.
Start by checking the power supply, earths and ECU connector – corrosion on the pins is common in older cars. It is also worth reading the fault memory with a diagnostic tool.
ECU versions
A locked ECU holds the data and immobiliser of the Superb it came from. It is bought by workshops that unlock, program and match it themselves. An unlocked ECU is prepared before dispatch, usually within 1–2 working days.
We treat every unit individually: depending on the part number, software and immobiliser, the PIN / CAR PASS code, a Virgin version, IMMO OFF, auto programming or cloning may be possible – but not always all of them. Ask about 03G906016GS before buying. More: ECU preparation options.
