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.

Will the 06E906023A ECU fit a 2012 Volkswagen Touareg 3.0?
It will if your unit carries the same VW number, 06E906023A. This is a used Bosch MED17.1.6 ECU in working order, from a 2012 Touareg 3.0 petrol.
Engine Control Unit Volkswagen Touareg 3.0 Bosch MED17.1.6 06E906023A 0261S06050
In the 2012 Volkswagen Touareg with the 3.0 petrol engine, the powertrain is managed by a Bosch MED17.1.6 ECU. The MED family is Bosch Motronic for direct-injection engines – the unit controls the injectors, ignition, throttle and a large number of sensors. This unit's VW number is 06E906023A and its Bosch number is 0261S06050. With electronics this complex, a working engine control unit is essential for the whole vehicle to run properly, and a failure often shows up as faults in several systems at once.
Numbers to compare
- 06E906023A – Volkswagen part number
- 0261S06050 – Bosch number, shown on the label as 0 261 S06 050
- MED17.1.6 – Bosch ECU type
The VW number ending in A is the basis for matching. A different letter in that position would indicate a different software or hardware version, so don't buy a replacement on model year and engine size alone.
Most common fault symptoms
- the Touareg won't start although the starter motor turns,
- no communication with the engine control unit,
- limp mode, engine warning light and loss of power,
- faults reported in several systems at the same time.
Start with the unit's power supply and earths, and the battery – in this vehicle, low voltage can trigger a cascade of fault codes.
Locked or unlocked – the difference
The locked version is an ECU holding the donor vehicle's data and immobiliser, intended for workshops that unlock, program and match it themselves. The unlocked version is prepared before dispatch, which usually takes 1–2 working days.
Whether PIN / CAR PASS, Virgin, IMMO OFF, auto programming or cloning will work depends on the part number, software and immobiliser – please ask before buying. Full details on the page ECU preparation options.
