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 036906034KA ECU fit a Polo or Seat with a 1.4 engine?
Yes, if your module shows the same VW number 036906034KA. We offer a used, working Magneti Marelli IAW 4TV.KA ECU for the 1.4 petrol engine in the Volkswagen Polo and Seat.
Engine Control Unit Volkswagen Polo, Seat 1.4 Magneti Marelli IAW 4TV.KA 036906034KA 6160130901
The same engine ECU was fitted to the Volkswagen Polo and to Seat models with the 1.4 petrol engine. It was made by Magneti Marelli, and the IAW 4TV.KA family covers modules controlling multi-point injection and ignition. Volkswagen gave it the number 036906034KA. In practice, it decides whether the engine starts, how smoothly it idles and when the engine warning light comes on.
Numbers on the sticker
- 036906034KA – Volkswagen part number
- 6160130901 – Magneti Marelli number; 61601.309.01 on the label
- IAW 4TV.KA – ECU type
ECUs in the 036906034 series differ in their final letters – here KA. The letters indicate the software or hardware version, so choose a replacement by the full number, not just by the make and engine size.
How to recognise a failure
- the engine does not fire after turning the key,
- the idle speed hunts or the engine stalls when braking,
- the engine warning light comes on with no visible sensor fault,
- the tester cannot connect to the ECU.
Before removing the module, check the connector for moisture and green deposits, and also check the engine earth.
ECU versions to choose from
You can buy the ECU locked or unlocked. The first option is a module with the data and immobiliser of the previous car – it makes sense if a workshop will unlock, program and adapt it itself. We prepare the second before dispatch, most often within 1–2 working days.
Which method will work – PIN / CAR PASS, Virgin, IMMO OFF, auto programming or clone – depends on the number, software and immobiliser in your car. So please ask before buying. You will find a description on the ECU preparation options page.
