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.

How does the 03L906018QN ECU differ from other EDC17C46 versions?
They all belong to the Bosch EDC17C46 family, but 03L906018QN is a specific version with Bosch number 0 281 019 117 – the letters QN define its software or hardware. The unit is used and fully working.
Engine Control Unit Skoda Bosch EDC17C46 03L906018QN 0281019117
The 03L906018QN engine control unit was made by Bosch as part of the EDC17C46 family, designed for diesel engines. The number 0281019117 is the manufacturer's designation, and 03L906018QN is the VW/Skoda part number. The unit comes from a Skoda; as the model is not known, the numbers decide compatibility.
Numbers to compare
- 03L906018QN – VW/Skoda number, version QN
- 0281019117 – Bosch number, shown on the sticker as 0 281 019 117
- EDC17C46 – family designation
03L906018 versions with different letters are not automatically interchangeable. Check that your ECU shows exactly 03L906018QN or Bosch number 0281019117.
Most common fault symptoms
- the engine will not start or only runs for a moment,
- reduced power appearing for no reason,
- the diagnostic tester cannot see the engine control unit,
- a fault after a voltage surge, e.g. from an incorrect jump-start.
Before you remove the ECU, make sure the problem does not lie with the immobiliser, the key or the power supply.
Preparation for fitting
You do not have to have the used ECU unlocked by us. The locked version, which retains the data and immobiliser of the car it came from, is usually bought by garages – they unlock, program and adapt it themselves. We get the unlocked version ready before dispatch; this normally takes 1–2 working days.
The range of options can vary: PIN / CAR PASS code, Virgin, IMMO OFF, auto-programming or clone are available depending on the part number, software version and type of immobiliser. Write to us before ordering and we will check this for 03L906018QN. Description on the engine control unit – variants page.
