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.

Is the 036906034KG the right ECU for a Polo 1.4?
Yes, if your current module has the same VW number 036906034KG and Magneti Marelli number 61601.315.01. We sell a used, working IAW 4TV.KG from a Volkswagen Polo 1.4 petrol.
Engine Control Unit Volkswagen Polo 1.4 Magneti Marelli IAW 4TV.KG 036906034KG 6160131501
This Magneti Marelli IAW 4TV.KG ECU came to us from a Volkswagen Polo 1.4 with a petrol engine. The VW part number is 036906034KG, and the manufacturer number 6160131501 is written on the label as 61601.315.01. The module converts sensor data into control signals for the injectors and ignition.
Identifying the module
- 036906034KG – Volkswagen (VW) part number
- 6160131501 – Magneti Marelli number, written on the label as 61601.315.01
- IAW 4TV.KG – Magneti Marelli ECU family
The letters KG at the end of the VW number identify the module version. A 036906034 ECU with a different ending may have different software.
Symptoms that may point to the ECU
- the engine will not run at all, even though the power supply is fine,
- the engine warning light comes on intermittently and the faults return after clearing,
- incorrect control of the injectors or ignition coils,
- increased fuel consumption and rough idling.
Before buying, it is worth ruling out a weak battery, the main relay and the earth leads.
Versions available
When choosing the version, think about who will do the programming. If a workshop does it, a locked module is enough – it keeps the data and immobiliser from the previous car. If you would rather receive an ECU ready for the next steps, choose the unlocked version – we prepare it before dispatch, usually within 1–2 working days.
The unlocking methods (PIN / CAR PASS, Virgin, IMMO OFF, auto programming, clone) do not suit every ECU – it depends on the number, software and immobiliser. Before buying, ask what is possible for the 036906034KG. Description of the options: auto24parts.com – 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 036906034KG? |
| 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. |
