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 is the difference between the 03G906016K and 03G906016DJ ECUs?
Both units belong to the EDC16U1 family and come from an Octavia 1.9 TDI, but they have different VW number suffixes and different Bosch numbers – they are different ECU versions. This unit has the number 03G906016K, Bosch 0281012237 and software 1039S07818.
Engine Control Unit Skoda Octavia 1.9 TDI Bosch EDC16U1 03G906016K 0281012237
The short K suffix distinguishes this ECU from other 03G906016 units used in the Octavia 1.9 TDI. The unit comes from a 2004 car and belongs to the Bosch EDC16U1 family. As a diesel engine control unit, it determines the fuel quantity, injection timing and turbocharger operation, and also takes part in key authorisation.
How to identify this ECU
- 03G906016K – VW/Skoda part number with the K suffix,
- 0281012237 – Bosch number, shown on the label as 0 281 012 237,
- 1039S07818 – Bosch software number,
- EDC16U1 – ECU family.
When replacing, stick to the number 03G906016K. A unit from the same family but with a different letter may have software that does not suit your engine.
Symptoms of a faulty engine control unit
- the engine cranks but will not fire, even though fuel is getting through,
- power drops and ECU faults appear in the memory,
- the engine warning light stays on after starting,
- the unit does not respond to the diagnostic tool.
Start by inspecting the connectors and wiring loom near the ECU – a chafed wire produces very similar symptoms.
Which option should you order?
If the ECU is going to a workshop with programming experience, the locked option is enough. The unit then holds the donor car's data and immobiliser, and the technician will unlock, program and match it. The unlocked option is prepared before the parcel is sent; this usually takes 1–2 working days.
Before you choose, ask about the methods available for 03G906016K. PIN / CAR PASS, Virgin, IMMO OFF, auto programming and cloning are not always possible – it depends on the part number, software and immobiliser. Read more on the ECU preparation options page.
