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.

Where on the ECU is the number 03C906024AF?
The VW number and Marelli number 61601.424.02 are printed on the label on the unit's casing. This used IAW 4HV.AF ECU in working order comes from a 2006–2007 vehicle with a 1.4 petrol engine.
Engine Control Unit Volkswagen, Seat, Skoda 1.4 Magneti Marelli IAW 4HV.AF 03C906024AF 6160142402
Three Group brands – Volkswagen, Seat and Skoda – used the Magneti Marelli IAW 4HV.AF ECU numbered 03C906024AF. The unit runs the 1.4 petrol engine in 2006–2007 vehicles and is responsible for injection, ignition and idle speed. Number 61601.424.02 is the designation in Magneti Marelli numbering.
Numbers on the label
- 03C906024AF – VW part number
- 6160142402 – Magneti Marelli number (61601.424.02)
- IAW 4HV.AF – ECU type
The 03C906024 base number is shared by many 1.4 ECUs, but the AF suffix identifies a specific version. Order a unit with the same suffix as the ECU in your vehicle.
Symptoms of a faulty unit
- the engine suddenly cuts out and won't restart,
- poor throttle response or running in limp mode,
- a series of sensor faults, although the sensors turn out to be fine when checked,
- damage after a voltage surge, e.g. after an incorrect jump start.
The first thing to check is the ECU's fuses and main relay.
ECU option
We offer two options. The first is an unlocked ECU – prepared by us before dispatch (usually 1–2 working days). The second is a locked ECU, with the data and immobiliser of the previous car, for workshops that carry out unlocking, programming and matching themselves.
The possible unlocking method – PIN / CAR PASS, Virgin, IMMO OFF, auto programming or cloning – is determined case by case, as it depends on the part number, software and immobiliser. For the 03C906024AF we will confirm it before you buy. See also: ECU preparation options.
