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 can I find the numbers 032906030E and 61600.355.01?
Both numbers are on the sticker on the casing of the Magneti Marelli IAW 1AV.V0 ECU. This used, working 032906030E module comes from a Volkswagen Polo 1.6 with a petrol engine.
Engine Control Unit Volkswagen Polo 1.6 Magneti Marelli IAW 1AV.V0 032906030E 6160035501
Magneti Marelli made IAW 1AV.V0 ECUs for Volkswagen, and this unit, with the letter E in the number 032906030E, comes from a Polo 1.6 with a petrol engine. The manufacturer number is 6160035501, written on the label as 61600.355.01. The module controls fuel injection and ignition, and a fault in it usually makes normal driving impossible.
Identifying the module
- 032906030E – Volkswagen (VW) part number
- 6160035501 – Magneti Marelli number, written on the label as 61600.355.01
- IAW 1AV.V0 – Magneti Marelli ECU family
The letter E and the 01 ending are what identify this version. When ordering, compare both numbers, because 032906030 versions differ in software or hardware.
When might the ECU be faulty?
- 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 032906030E. Description of the options: auto24parts.com – ECU preparation options.
Questions and answers
| 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. |
| How long does it take to prepare the unlocked version? |
| Usually 1–2 working days before dispatch. Beforehand we confirm which unlocking method is possible for this unit. |
| Are 6160035501 and 032906030E the same ECU? |
| Yes, they are two numbers of one module: 032906030E is the VW number and 6160035501 is the Magneti Marelli number. |
| Is the module working and covered by a warranty? |
| Yes – the ECU is used, working and in good condition. You will find the warranty period in the product features table. |
