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 do you check whether the 06J906027HD will fit your car?
Simply compare the sticker on your current ECU with the VW number 06J906027HD and the Bosch number 0 261 S10 331. The unit on offer is a used, working Bosch MED17.5.2.
Engine Control Unit Volkswagen Bosch MED17.5.2 06J906027HD 0261S10331
Replacing an engine control unit starts with reading the sticker – that is how you find out whether you need this exact version. This unit is a Bosch MED17.5.2 with the manufacturer number 0261S10331, designed for a Volkswagen with a direct-injection petrol engine. It is used, in working order and in good condition.
Numbers worth checking
- 06J906027HD – VW part number
- 0261S10331 – Bosch number, as written on the sticker: 0 261 S10 331
- MED17.5.2 – ECU type
The letters HD distinguish it from other 06J906027 ECUs. Each ending denotes a different hardware or software version.
Symptoms of a faulty engine ECU
- the fuel pump or radiator fan is not switched on, although the components themselves work,
- engine warning light with internal ECU fault codes,
- fuel pressure control faults even though the high-pressure pump and sensor are fine,
- injectors not being triggered during cranking.
Also check that the connector is not damp and that the power supply wires are not broken.
Locked or unlocked variant
You can order the 06J906027HD unit locked or unlocked. The former keeps the data and immobiliser of the previous car, so before fitting it needs to be unlocked, programmed and matched by a workshop. We prepare the latter before dispatch, usually in 1–2 working days.
PIN / CAR PASS, Virgin, IMMO OFF, auto programming or clone are not available for every ECU – the part number, software and immobiliser decide. Ask before you order. Also have a look at the ECU variants page.
Questions and answers
| What needs to be done after fitting this unit? |
|---|
| With the locked version: unlock it, program it and match it to the immobiliser. With the unlocked one, the scope of work depends on the preparation method, which we confirm before purchase. |
| Do 0261S10331 and 06J906027HD refer to the same ECU? |
| Yes. 0261S10331 is the number assigned by Bosch, and 06J906027HD is the Volkswagen part number – both describe the same unit. |
| Can I fit an ECU with a different final letter from 06J906027HD? |
| 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 the unit in and does it have a warranty? |
| The unit is used, in working order and in good condition. You will find the warranty period in the product features table. |
