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.

The Audi A4 and Volkswagen vehicles with diesel engines – these are the cars this ECU was used in. It is a Bosch module with number 0281010226 and VW part number 038906019BR. It handles fuel metering and monitors the running of the engine. We do not state the engine size, so compare the numbers. The part is used, in working order and in good condition.
Numbers to check
- 038906019BR – VW part number
- 0281010226 – Bosch number, as printed on the label 0 281 010 226
The BR suffix in the VW number indicates the software and hardware version. 038906019 ECUs come in many versions, so compare the whole number.
Symptoms that may point to the ECU
- no start despite a working starter motor,
- the ECU does not respond to the diagnostic tester,
- limp mode with no sensor faults,
- failure after a voltage spike or water ingress.
First check the earths, power supply and the condition of the connector pins. If these are all in order and the symptoms persist, the module itself may be the cause. Reading the fault memory will help narrow down the diagnosis before you buy.
Locked or unlocked – your choice
If you choose the locked version, you will receive the ECU with the data and immobiliser of the previous vehicle – for workshops that will unlock, program and match it themselves. If you choose the unlocked version, you will get a module prepared before dispatch; this usually takes 1–2 working days.
Whether PIN / CAR PASS, Virgin, IMMO OFF, auto programming or cloning will be possible depends on the number, software and immobiliser. Please ask before buying. More: ECU preparation options.
