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 does EDC16U1 mean on the 03G906016DJ ECU?
EDC stands for Bosch Electronic Diesel Control, and EDC16U1 is a family of diesel engine control units. This unit, numbered 03G906016DJ and 0281011883, comes from a 2004 Octavia 1.9 TDI and is fully working.
Engine Control Unit Skoda Octavia 1.9 TDI Bosch EDC16U1 03G906016DJ 0281011883
This unit also belongs to the Bosch EDC16U1 family of electronic diesel control units. In the 2004 Skoda Octavia 1.9 TDI, the 03G906016DJ ECU was responsible for fuel metering, injection timing and boost pressure. Bosch gave it the number 0 281 011 883.
Numbers and markings
- 03G906016DJ – VW/Skoda part number,
- 0281011883 – Bosch number (0 281 011 883 on the label),
- EDC16U1 – ECU family.
The 03G906016 and 03G906021 ECUs are different number series – do not swap them without checking. The DJ suffix, which identifies the unit version, also matters.
Fault symptoms
- no start, or starting only after several attempts,
- unexpectedly going into limp mode,
- no communication with the diagnostic tool,
- damage after the unit got wet or after a failed software update.
The first step is to check the power supply and earth and read the fault codes – a crankshaft position sensor fault can also prevent the engine from starting.
Choosing an option
For this ECU you can order a locked or an unlocked version. The first keeps the data and immobiliser of the Octavia it came from – useful for a workshop that unlocks, programs and matches units in-house. The second is prepared by us before dispatch, which usually takes 1–2 working days.
Depending on the part number, software and immobiliser, different methods are possible – PIN / CAR PASS, Virgin, IMMO OFF, auto programming or cloning. For 03G906016DJ we confirm them individually before you buy. Details on the ECU preparation options page.
