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.

What does the letter P in the number 032906030P mean?
The letter P indicates the version of the Magneti Marelli IAW 1AV.V0 engine ECU numbered 61600.355.02. This used, working 032906030P module comes from a Volkswagen Polo 1.6 petrol.
Engine Control Unit Volkswagen Polo 1.6 Magneti Marelli IAW 1AV.V0 032906030P 6160035502
When looking for an ECU for a Polo 1.6 petrol, first check the letter at the end of the VW number – on this unit it is P, giving 032906030P. The module belongs to the Magneti Marelli IAW 1AV.V0 family and has manufacturer number 6160035502 (as shown on the label: 61600.355.02). It is responsible for fuel injection and ignition.
Numbers to compare
- 032906030P – Volkswagen (VW) part number
- 6160035502 – Magneti Marelli number, written on the label as 61600.355.02
- IAW 1AV.V0 – Magneti Marelli ECU family
The 02 ending of the Magneti Marelli number also identifies the version. If both numbers match the label in your car, the ECU is the right one.
Symptoms that may point to the 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.
Before deciding to replace it, inspect the connectors and wiring loom for corrosion and chafing.
Locked or unlocked version?
We offer this ECU in two versions. The locked one contains the data and immobiliser of the previous car – it is chosen by workshops that will unlock, program and adapt the module themselves. We prepare the unlocked one before dispatch, usually within 1–2 working days.
Not every preparation method is possible for every ECU: PIN / CAR PASS, Virgin, IMMO OFF, auto programming or clone depend on the number, software and immobiliser. Please ask us before buying. Details: ECU preparation options.
Questions and answers
| How long does it take to prepare the unlocked version? |
|---|
| Usually 1–2 working days before dispatch. Beforehand we confirm which unlocking method is possible for this unit. |
| Are 6160035502 and 032906030P the same ECU? |
| Yes, they are two numbers of one module: 032906030P is the VW number and 6160035502 is the Magneti Marelli number. |
| Does this module fit every Polo? |
| No. Different engine ECUs were used in this model, so compatibility is decided by the number on the label, not by the car model alone. |
| What condition is this part in? |
| Used, in good condition and fully working. You will find the warranty period in the product features table. |
