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 IAW 4LV.G 036906034AM unit fit my Golf 1.6?
It fits if your Golf with a 1.6 petrol engine has an ECU with the same VW number 036906034AM and Magneti Marelli number 61600.518.08. The unit is used and working.
Engine Control Unit Volkswagen Golf 1.6 Magneti Marelli IAW 4LV.G 036906034AM 6160051808
The AM suffix in the number 036906034AM distinguishes this ECU from many similar Magneti Marelli units used in the Golf 1.6. It belongs to the IAW 4LV.G family and is designed for a petrol engine – it controls the injectors, ignition coil and throttle. The manufacturer number is 6160051808.
Numbers to compare
- 036906034AM – VW part number
- 6160051808 – Magneti Marelli number, on the label 61600.518.08
- IAW 4LV.G – ECU family
Several versions of the 036906034 ECU, differing in the letters at the end, were fitted to the Golf 1.6. These letters denote the software or hardware version, so a replacement must have exactly the AM suffix.
Possible signs of a fault
- the car starts for a moment and then stalls straight away,
- the idle speed fluctuates or is too high,
- no spark or no injection with working components,
- the ECU does not respond to tester requests.
Before replacing it, check the main relay, fuses and the condition of the wiring at the unit connector.
Versions: locked or unlocked
We carry out the unlocking before dispatch – for the unlocked version this usually takes 1–2 working days. In the locked version, the unit keeps the data and immobiliser of the car it came from; this is the option for workshops that will unlock, program and match it themselves.
The available methods (PIN / CAR PASS, Virgin, IMMO OFF, auto programming, clone) vary depending on the part number, software and immobiliser, so please ask about them before you buy. More on the ECU preparation options page.
