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 the KQ suffix in 03L906022KQ mean?
The letters KQ denote a specific software or hardware version of the 03L906022 ECU. This Bosch EDC17CP14 module (number 0281015380) is used and working, available locked or unlocked.
Engine Control Unit Volkswagen Bosch EDC17CP14 03L906022KQ 0281015380
Bosch assigned this ECU the number 0 281 015 380, and Volkswagen 03L906022KQ. The 0 281 prefix clearly indicates a diesel engine ECU, and the EDC17CP14 family belongs to the Bosch Electronic Diesel Control series. The module controls injection and responds to sensor signals; we do not state the specific Volkswagen model.
Numbers on the label
- 03L906022KQ – VW catalogue number; the letter suffix indicates the version
- EDC17CP14 – Bosch Electronic Diesel Control ECU family
- 0 281 015 380 – Bosch number as written on the sticker; in catalogues without spaces: 0281015380
To order, the full VW number including the letters KQ must match. The Bosch number is additional confirmation that it is the same module.
How does an ECU fault show itself?
- software cannot be read or written via the diagnostic port,
- internal ECU faults stored in the fault memory,
- faults returning straight after being cleared, even though the wiring is sound,
- the engine cutting out or jerking while driving even though the ancillaries are working.
Before removal, check the power supply and earths, and read the fault memory of the other control units.
Choosing the ECU version
There are two options to choose from. The unlocked version is prepared before dispatch, which usually takes 1–2 working days. The locked version reaches you with the data and immobiliser of the car it came from; unlocking, programming and adaptation are then carried out by a workshop.
Whether PIN code / CAR PASS, Virgin, IMMO OFF, auto programming or clone will be possible for the 03L906022KQ ECU depends on its number, software and immobiliser. Before buying, ask which solution suits your car.
You will find a full description of the options here: ECU preparation options.
Questions and answers
| Is the ECU tested and covered by a warranty? |
|---|
| Yes, it is a working used module in good condition. You will find the warranty period in the product features table. |
| Is the EDC17CP14 marking alone enough for matching? |
| No. EDC17CP14 is a family covering many ECU versions; matching is decided by the VW number and the manufacturer's number. |
| Will the 03L906022KQ ECU start the engine immediately after fitting? |
| Not the locked version – it has to be programmed and adapted to the immobiliser. With the unlocked version, it depends on the preparation method, which we agree before purchase. |
| Who can program the locked version? |
| A workshop or auto electronics specialist with equipment for programming ECUs and adapting immobilisers. If you do not have access to this, choose the unlocked version. |
