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 036906034EA ECU from a 2000 Lupo 1.4 fit your car?
If your Lupo has a unit with VW number 036906034EA and number 61600.638.00, then yes. This used, working Magneti Marelli IAW 4LV.SB ECU comes from a 2000 Volkswagen Lupo 1.4 (petrol).
Engine Control Unit Volkswagen Lupo 1.4 Magneti Marelli IAW 4LV.SB 036906034EA 6160063800
An ECU from a 2000 Volkswagen Lupo 1.4, designated IAW 4LV.SB by Magneti Marelli. VW number 036906034EA distinguishes it from other 036906034 units used in the Lupo. It runs the petrol engine: fuel injection, ignition and idle.
Numbers to compare
- 036906034EA – VW part number
- 6160063800 – Magneti Marelli number, as printed on the label: 61600.638.00
- IAW 4LV.SB – ECU type designation
The EA suffix is key here: 036906034 numbers with other letters are different ECU versions, often with different software. The car's model year helps, but it is no substitute for comparing the number.
What to look out for – symptoms
- the engine suddenly cuts out and is difficult to restart,
- engine warning light on with an ECU fault,
- no activation of the fuel pump or injectors,
- a damp or corroded unit connector.
Before buying, it is worth checking the fuses, relay and earths – wiring faults often look like an ECU failure.
How to choose a version
You have two options. The first is an unlocked ECU – we prepare it before dispatch, usually within 1–2 working days. The second is a locked ECU, with the data and immobiliser of the car it came from; this version is for workshops that will unlock, program and match it themselves.
Whether PIN / CAR PASS, Virgin, IMMO OFF, auto programming or a clone can be applied depends on the part number, software and immobiliser – please ask about this before you buy. Description of the options: ECU preparation options.
