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.

Where can you find the number 03E906033D on your ECU?
Look for the sticker on the unit's casing – next to the VW number 03E906033D it shows the number 5WP40192 05. We are offering a used, working petrol engine control unit.
Engine Control Unit Volkswagen 03E906033D 5WP4019205
On this ECU, the number 03E906033 is followed by just one letter – D. The unit comes from a petrol-engined Volkswagen and carries a second number, 5WP4019205. It controls injection, ignition and engine operation based on sensor readings. It is used, in working order and in good condition.
What is on the label
- 03E906033D – VW number with the ending D
- 5WP4019205 – 5WP… number (Siemens VDO / Continental numbering), as written on the label: 5WP40192 05
The label is usually stuck on top of the casing; sometimes you need to remove the unit to read it. The letter D defines the version – a 03E906033 unit with a different ending is a different ECU.
Symptoms of a faulty ECU
- the engine will not start, although the starter motor cranks normally,
- uneven revs and loss of power,
- injector, coil or throttle circuit faults,
- the ECU does not respond during diagnostics.
Before you order a new unit, inspect the connector for corrosion and check the power supply fuses.
Locked or unlocked
We prepare the unlocked 03E906033D ECU before dispatch – this usually takes 1–2 working days. The locked one has the previous car's data and immobiliser stored; it is bought by workshops that will unlock, program and match the unit themselves.
Whether PIN / CAR PASS, Virgin, IMMO OFF, auto programming or clone can be used depends on the part number, software and immobiliser, so ask us before you buy. You will find a description here: ECU preparation options.
