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
An engine control unit works in harsh conditions: changing temperatures, moisture and vibration. That is why it is worth checking the condition of the housing and connectors before buying. 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 0 261 207 696 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. If your control unit has a different number, write to us - we may have a version that suits your engine.
How to recognise a faulty control unit
- an engine fault appears after the battery has been replaced,
- the control unit's supply voltage is unstable,
- power drops once the car has warmed up,
- the engine goes into limp mode for no obvious reason.
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.
Locked or unlocked variant?
In the unlocked variant, we prepare the module before dispatch - this usually takes 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. The available methods, such as PIN / CAR PASS, Virgin, IMMO OFF, auto-programming or cloning, vary depending on the number, software and immobiliser. See our ECU preparation options and contact us before buying.
