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 06J906026AR fit a Volkswagen 2.0 TFSI?
This ECU is intended for a Volkswagen with the 2.0 TFSI engine. It fits if your unit has the same VW number, 06J906026AR, or the Bosch number 0261201951 – it is a used, working Bosch MED17.5.
Engine Control Unit Volkswagen 2.0 TFSI Bosch MED17.5 06J906026AR 0261201951
The 2.0 TFSI direct-injection petrol engine needs an ECU that meters fuel precisely and controls the ignition – in this unit that role is performed by a Bosch MED17.5. The VW number 06J906026AR and the Bosch number 0261201951 identify the specific version of the unit. The ECU is used, in working order and in good condition.
Identifying the unit
- 06J906026AR – VW number
- 0261201951 – Bosch number, shown on the label as 0 261 201 951
- MED17.5 – Bosch ECU type
The 2.0 TFSI engine designation alone is not enough for matching. What counts is the number with the AR ending, which indicates the hardware or software version.
Symptoms of a faulty engine ECU
- interrupted or failed programming, after which the unit does not respond,
- the fuel pump or radiator fan is not switched on, although the components themselves work,
- fuel pressure control faults even though the high-pressure pump and sensor are fine,
- signs of moisture, corrosion or overheating on the connector and casing.
It is worth reading the fault memory first and checking the power supply and fuses, as the fault does not necessarily lie in the unit itself.
Locked versus unlocked version
A locked unit has the data and immobiliser of the car it was removed from stored in its memory. This is the solution for workshops: they will unlock, program and match it to the vehicle themselves. We prepare the unlocked one in-house before the parcel is sent, which usually takes 1–2 working days.
Which unlocking method can be used – a PIN / CAR PASS code, Virgin, IMMO OFF, auto programming or clone – follows from the part number, software and immobiliser. That is why it is worth asking before you buy. More: ECU preparation options.
Questions and answers
| Will the car start straight away once the 06J906026AR ECU is fitted? |
|---|
| Not with the locked version – the unit has to be unlocked, programmed and matched to the immobiliser. With the unlocked version it depends on the preparation method, which we agree before purchase. |
| Is 0 261 201 951 on the label the same number as 0261201951? |
| Yes, it is the same Bosch number – on the sticker it is written with spaces, in catalogues usually without. |
| Can I fit an ECU with a different final letter from 06J906026AR? |
| We do not recommend it without consulting us. The letter denotes the hardware or software version, so a different ending may mean it is not compatible. |
| What condition is this ECU in? |
| It is a used part, in working order and in good condition. You will find the warranty period in the product features table. |
