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 can you check whether the 61601.450.01 unit will fit an Ibiza 1.4?
Compare the label on your current ECU: Marelli number 61601.450.01 and VW number 03C906024AS should both match. This MY2 4HV.AS unit is used and in working order.
Engine Control Unit Volkswagen, Seat Ibiza 1.4 Magneti Marelli MY2 4HV.AS 03C906024AS 6160145001
Magneti Marelli number 61601.450.01 is the main distinguishing feature of this ECU – VW number 03C906024AS also appears with other Marelli numbers. The MY2 4HV.AS family unit manages the 1.4 petrol engine in the Seat Ibiza and Volkswagen models: it meters the fuel, sets the ignition and controls idle speed.
How to identify this unit
- 6160145001 – Magneti Marelli number, shown on the label as 61601.450.01
- 03C906024AS – VW part number
- MY2 4HV.AS – type designation
When matching, pay attention to both parts of the marking: the AS suffix in the VW number and the full Marelli number. Even a difference in the last digits may mean different software.
What to look out for when diagnosing
- the starter turns but the engine won't fire,
- no control of the fuel pump or injectors,
- internal ECU faults stored in memory,
- hunting idle speed with no mechanical cause.
Check the immobiliser too – a key that fails authorisation has a similar effect to a faulty unit.
How we prepare the ECU for dispatch
The unlocked version is prepared before the parcel is sent, usually within 1–2 working days. The method depends on the number 03C906024AS, the software and the vehicle's immobiliser – options include PIN / CAR PASS, Virgin, IMMO OFF, auto programming or cloning, but not every one is feasible for this unit. Please ask before buying.
The other option is the locked version – with the previous vehicle's data and immobiliser, intended for workshops that unlock, program and match the ECU themselves. Details of both options: ECU preparation options.
Questions and answers
| I have a 03C906024AS with a different Marelli number – what should I do? |
|---|
| Send us a photo of the label. We'll check whether the difference in Marelli numbers matters for your vehicle. |
| Will the 03C906024AS start the engine straight after fitting? |
| Not in the locked version – it needs to be programmed and matched to the immobiliser. With the unlocked version, it depends on the preparation method, which we agree before dispatch. |
| Is the unit in working order? |
| Yes, it is in working order and in good condition, although used. You will find the warranty period in the product features table. |
Before buying, get in touch: contact@auto24parts.com. Send the numbers from the label and we'll confirm the available preparation options.
