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.

Does the 06A906018GR ECU fit a Volkswagen or Skoda 2.0?
It fits if your current unit has the same VW number and Bosch number 0 261 206 923. This is a used ECU in working order for the 2.0 petrol engine.
Engine Control Unit Volkswagen, Skoda 2.0 Bosch 06A906018GR 0261206923
A two-litre petrol engine in a Volkswagen or Skoda needs a working ECU to run smoothly and start without trouble. This Bosch unit, VW number 06A906018GR and number 0 261 206 923, runs the 2.0 engine: it meters the fuel, controls the ignition and responds to sensor signals.
Markings to check
- 06A906018GR – VW part number
- 0261206923 – Bosch number, as shown on the label: 0 261 206 923
The letters GR distinguish this unit from other 06A906018 ECUs, such as the GH version. The final letters of the VW number denote the software or hardware version.
Symptoms that may point to the ECU
- the engine starts briefly and then dies,
- no connection to diagnostics despite a working OBD socket,
- incorrect control of the ignition coils or injectors,
- the engine shutting down by itself while driving.
Before replacing it, measure the power supply and the continuity of the wires between the ECU and the components.
How we prepare the ECU for dispatch
The unlocked version is prepared before the parcel is sent, usually within 1–2 working days. The method depends on the number 06A906018GR, the software and the vehicle's immobiliser – options include PIN / CAR PASS, Virgin, IMMO OFF, auto programming or cloning, but not every one is feasible for this unit. Please ask before buying.
The other option is the locked version – with the previous vehicle's data and immobiliser, intended for workshops that unlock, program and match the ECU themselves. Details of both options: ECU preparation options.
Questions and answers
| Will it fit every 2.0 petrol engine? |
|---|
| No. The VW number and Bosch number decide the match, not the engine size alone – different ECU versions were used in 2.0 vehicles. |
| Is adaptation needed after replacing the ECU? |
| Usually, yes – after fitting, it is worth carrying out the matching and checking the fault memory. The scope of work depends on the version you choose; we'll advise before you buy. |
| Is there a warranty on the ECU? |
| Yes. You will find the warranty period in the product features table. The unit is used, in working order and in good condition. |
