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:

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.

Engine Control Unit Volkswagen 1.9 TDI Bosch 038906018HA 0281010243
The 1.9 TDI engine in a Volkswagen won't run without a working ECU – it calculates the diesel fuel quantity, sets the start of injection and manages starting. This Bosch unit carries VW number 038906018HA, and we describe its condition as used, in working order and good. The stored fault codes also make diagnostics easier.
Numbers to check on the casing
- 038906018HA – VW part number
- 0281010243 – Bosch number (0 281 010 243 on the label)
- 1.9 TDI – the engine the unit comes from
The 1.9 TDI engine alone does not determine compatibility, as many ECU versions were used under this designation. What counts is the VW number with its HA suffix, which indicates the software or hardware version.
Fault symptoms in the 1.9 TDI diesel
- difficult starting or no start, especially from cold,
- loss of power and switching to limp mode,
- injection circuit faults or internal ECU faults,
- no connection to the tester.
Before diagnosing the unit, check the power supply, earths and connector – the most common source of similar faults. It is also worth reading the fault codes before deciding on a replacement.
Versions on sale
Choose between the locked and unlocked version. The first holds the data and immobiliser of the previous vehicle and goes mainly to workshops that unlock, program and match the ECU to your Volkswagen themselves. The second is prepared before dispatch, usually within 1–2 working days.
The availability of methods (PIN / CAR PASS, Virgin, IMMO OFF, auto programming, cloning) depends on the part number, software and immobiliser, so check what is possible before buying. Description of the options: ECU preparation options.
