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.

Where should I look for the number 036906034DT on a Lupo 1.4 ECU?
Number 036906034DT is printed on the label on the casing, together with Magneti Marelli number 61600.637.00. We offer this IAW 4LVUB unit as a used, working engine control unit for the petrol Volkswagen Lupo 1.4.
Engine Control Unit Volkswagen Lupo 1.4 Magneti Marelli IAW 4LVUB 036906034DT 6160063700
The label on the 036906034DT ECU carries two numbers: the Volkswagen one and the Magneti Marelli one (61600.637.00). The IAW 4LVUB is a Magneti Marelli ECU that manages fuel injection and ignition of the petrol engine in the Volkswagen Lupo 1.4. When the unit fails, the engine often will not start at all and the tester cannot see the ECU. In that case, replacing it with a unit with an identical number solves the problem.
Numbers on the label
- 036906034DT – VW part number
- 6160063700 – Magneti Marelli number, printed as 61600.637.00
- IAW 4LVUB – type designation
The letters DT at the end indicate the ECU version. 036906034 units with a different ending have different software or hardware, so check the full number before placing your order.
Is the ECU to blame? Typical symptoms
- no start with a working battery and starter,
- the engine stalls after running for a few seconds,
- incorrect injector activation,
- no connection to the ECU during diagnostics.
It is worth ruling out problems with the unit's earth and power supply, as well as corrosion on the plug pins, beforehand.
Locked or unlocked – which to choose?
The ECU in the locked version holds the stored immobiliser and data of the donor car; it is chosen by workshops that unlock, program and match it themselves. We prepare the unlocked version in-house before dispatch – normally within 1–2 working days.
Not every method is possible for every part number: PIN / CAR PASS, Virgin, IMMO OFF, auto programming or clone. It depends on the part number, software and immobiliser – please ask before ordering. Details: ECU preparation options.
