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.

What does the number 5WP4024501 on the 06A906033DC ECU mean?
It is the Siemens VDO number of this unit, written on the label as 5WP40245 01. The VW number is 06A906033DC – together they identify a used, working petrol engine control unit.
Engine Control Unit Volkswagen Siemens VDO 06A906033DC 5WP4024501
Siemens VDO is the manufacturer of this ECU, and the number 5WP4024501 comes from its numbering system. Volkswagen gave the unit the number 06A906033DC. The ECU runs a petrol engine: using sensor signals, it determines the fuel quantity, ignition timing and idle speed. The unit is used, in working order and in good condition.
Numbers on the label
- 06A906033DC – Volkswagen part number, ending DC
- 5WP4024501 – Siemens VDO number, shown on the label as 5WP40245 01
On the sticker the Siemens number is split by a space before the last two digits. The DC ending in the VW number describes the version – 06A906033 ECUs with other letters, e.g. DR or AS, have different software or hardware.
Symptoms that point to the unit
- the engine stalls when stationary or cannot hold its revs,
- no spark or injection even though the components are fine,
- engine warning light on and ECU memory faults,
- the unit does not respond to the tester.
Check the earths, power supply and connector first – the cause often lies there rather than in the ECU itself. Read the fault codes as well.
Two variants of the 06A906033DC ECU
Locked: a unit with the previous car's data and immobiliser, aimed at workshops that will carry out the unlocking, programming and matching themselves. Unlocked: we prepare it before dispatch, which usually takes 1–2 working days.
Remember that not every method – PIN / CAR PASS, Virgin, IMMO OFF, auto programming or clone – is available for every unit; it depends on the part number, software and immobiliser. Ask before you buy. You will find a description on the ECU preparation options page.
