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.

Does the 032906030AB ECU fit a Polo 1.6?
Yes, if your current ECU has number 032906030AB and Magneti Marelli number 61600.355.03. This is a used, working IAW 1AV.V0 module from a Volkswagen Polo 1.6 petrol.
Engine Control Unit Volkswagen Polo 1.6 Magneti Marelli IAW 1AV.V0 032906030AB 6160035503
Version AB is one of the variants of the 032906030 ECU for the Volkswagen Polo 1.6 with a petrol engine. The module belongs to the Magneti Marelli IAW 1AV.V0 family, and its manufacturer number 6160035503 is written on the label as 61600.355.03. The ECU meters the fuel and sets the ignition based on signals from the sensors.
Markings on the casing
- 032906030AB – Volkswagen (VW) part number
- 6160035503 – Magneti Marelli number, written on the label as 61600.355.03
- IAW 1AV.V0 – Magneti Marelli ECU family
The version is determined by the letters AB at the end of the VW number and the 03 ending of the Magneti Marelli number. Both numbers must match the label in your car.
Symptoms of a faulty engine ECU
- the engine will not start, even though the starter turns and fuel is getting through,
- the engine warning light is on and the memory holds injection or ignition faults with no component failure,
- the diagnostic tester cannot connect to the ECU,
- the engine stalls or idles unevenly.
The first step should be reading the fault codes and checking the wiring – many faults lie in the cables, not in the module.
Locked or unlocked – which to choose?
The 032906030AB ECU can be ordered locked or unlocked. The locked version holds the data and immobiliser of the car it came from – your workshop then carries out the unlocking, programming and adaptation.
With the unlocked version we take care of the preparation and do it before dispatch (usually 1–2 working days). Bear in mind that whether a PIN / CAR PASS, Virgin version, IMMO OFF, auto programming or a clone can be used depends on the number, software and immobiliser – write to us before buying. See also ECU preparation options.
Questions and answers
| Can a workshop handle the locked version? |
|---|
| Yes, if it has equipment for programming and immobiliser adaptation. Without such equipment, it is better to choose the unlocked version. |
| Will the engine start straight away after fitting the 032906030AB? |
| Not with the locked version – the ECU must be programmed and adapted to the immobiliser. With the unlocked version it depends on the preparation method we agree before dispatch. |
| Can I fit an ECU with a different letter at the end of the number? |
| We do not recommend it without checking with us. The letter indicates the software or hardware version, so the safest choice is a module with an identical VW number. |
| Is there a warranty on the ECU? |
| Yes. We sell it used, working and in good condition. You will find the warranty period in the product features table. |
