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.

How an engine control unit works
A modern engine control unit also monitors exhaust emissions and signals faults with a warning light. A module failure usually prevents the engine from running normally or puts it into limp mode. The module stores fault codes which, once a diagnostic tool is connected, help to establish whether the sensors, the wiring or the control unit itself is to blame.
How to match this part
Compare number 5WP46581 06 in full with the number on your control unit. Different versions were fitted to the same models, so it is the number that decides the match, not the model alone. The numbers given come from our listing; always compare them with the markings on your control unit.
How to recognise a faulty control unit
- the engine only runs intermittently,
- the control unit gets hot or resets,
- injector faults appear,
- the diagnostic tool cannot detect the module.
Before you buy a control unit, check the fuses, power supply, earth and sensors - a damaged wiring loom or crankshaft position sensor can also cause similar symptoms.
Which variant should you choose: locked or unlocked?
The unlocked variant means that we prepare the module for you before dispatch; this usually takes approx. 1-2 working days. The locked variant is a module with the previous vehicle's data; the unlocking, programming and matching to the car are carried out by your own garage. Whether the chosen method (PIN / CAR PASS, Virgin, IMMO OFF, programming, cloning) can be used depends on the specific control unit number, its software and the immobiliser. Before buying, send us the number of your control unit. More details: what locked and unlocked mean for an engine control unit.
