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 03C906024AS ECU differ from the 03C906024H version?
Both units share Marelli number 61601.363.04, but have a different VW number suffix and a different type designation – here MY2 4HV.AS. When choosing an ECU for an Ibiza 1.4, go by the full VW number.
Engine Control Unit Volkswagen, Seat Ibiza 1.4 Magneti Marelli MY2 4HV.AS 03C906024AS 6160136304
The MY2 4HV.AS designation indicates a Magneti Marelli ECU from the MY2 family, designed for the 1.4 petrol engine. This unit carries VW number 03C906024AS and was used in the Seat Ibiza and in Volkswagen models. It is responsible for fuel injection and ignition, so any fault is immediately noticeable in the way the engine runs.
Markings on the label
- 03C906024AS – VW part number with the AS suffix
- 6160136304 – Magneti Marelli number, written 61601.363.04
- MY2 4HV.AS – ECU type
The AS suffix distinguishes this unit from other 03C906024 ECUs. The Marelli number is sometimes shared by several versions, so please give us both numbers from the label when ordering.
Typical fault symptoms
- the engine warning light stays on and cleared faults return immediately,
- the engine jerks, loses power or goes into limp mode,
- the tester cannot see the ECU,
- starting problems after water ingress or a voltage spike.
The first step should be measuring the supply voltage and checking the earths – only then replace the unit.
Two options to choose from
If you have a workshop with your own programming equipment, choose the locked version: the ECU retains the data and immobiliser from the vehicle it came from, and you carry out the unlocking, programming and matching yourself. The unlocked version is prepared in-house before dispatch – this usually takes 1–2 working days.
Not every method can be used on every unit: PIN / CAR PASS, Virgin, IMMO OFF, auto programming or cloning. It depends on the part number, software version and type of immobiliser, so before buying, ask what is possible for the 03C906024AS. More on the page ECU preparation options.
