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 03L906022JL and 03L906022QJ?
Both ECUs are Bosch EDC17CP14 units from a 2009 Superb 2.0 TDI, and both have the second number 03L906022GA. However, they differ in the main number and the Bosch number – this one has 03L906022JL and 0281015300, so it is a different software or hardware version.
Engine Control Unit Skoda Superb 2.0 TDI Bosch EDC17CP14 03L906022JL 0281015300 03L906022GA
EDC17CP14 is a family of Bosch ECUs for diesel engines, and the 03L906022JL unit is one of its members. It comes from a 2009 Skoda Superb 2.0 TDI. It controls injection and turbo boost, and the Bosch number 0 281 015 300 unambiguously identifies its hardware version.
How to identify this ECU
- 03L906022JL – main VW/Skoda number,
- 03L906022GA – second VW number,
- 0281015300 – Bosch number, shown on the label as 0 281 015 300,
- EDC17CP14 – ECU family.
The number 03L906022GA appears on several units, so it is not enough for matching. Compare 03L906022JL – the letters JL identify a specific version.
Fault symptoms
- the engine will not start and the unit does not respond,
- the car suddenly goes into limp mode,
- the glow plug light flashes,
- damage after a voltage surge or a failed software modification.
Start with the battery voltage and the earth leads, then read the fault codes with a diagnostic tool.
Locked and unlocked options – how do they differ?
The difference concerns the immobiliser and data. A locked unit still has them from the previous car – it is intended for workshops that will unlock, program and match it themselves. An unlocked unit is prepared by us before dispatch, usually within 1–2 working days.
PIN / CAR PASS, Virgin, IMMO OFF, auto programming, cloning – these are the possible methods, but their availability depends on the part number, software and immobiliser. Ask about 03L906022JL before ordering. Details: ECU preparation options.
