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.

Looking for a Bosch 0261S06066 ECU for your Volkswagen?
This is exactly that unit – Bosch number 0261S06066 (on the label: 0 261 S06 066) and VW number 06J906026FK. The MED17.5 ECU is used, in working order and in good condition.
Engine Control Unit Volkswagen Bosch MED17.5 06J906026FK 0261S06066
Sometimes the Bosch number on the sticker is easier to read than the VW number – on this unit it is 0261S06066, corresponding to the Volkswagen number 06J906026FK. The ECU belongs to the MED17.5 family, i.e. Bosch Motronic for direct-injection petrol engines. It controls fuel metering and ignition based on sensor data.
How to identify this ECU
- 06J906026FK – VW part number
- 0261S06066 – Bosch number, written 0 261 S06 066
- MED17.5 – ECU family
The FK ending defines the hardware or software version – the neighbouring number 06J906026FH is already a different ECU.
Typical failure symptoms
- signs of moisture, corrosion or overheating on the connector and casing,
- injectors not being triggered during cranking,
- fuel pressure control faults even though the high-pressure pump and sensor are fine,
- limp mode with reduced power that the sensor readings do not explain.
Before you order a new unit, check the fuses, power supply relay and engine earths.
How do we prepare this ECU?
We sell the 06J906026FK ECU in two variants. We prepare the unlocked one before dispatch; this usually takes 1–2 working days. The locked one keeps the data and immobiliser of the previous vehicle, and unlocking, programming and matching it is left to the workshop.
Not every method is possible for every unit – PIN / CAR PASS, Virgin, IMMO OFF, auto programming or cloning depend on the part number, software version and immobiliser. Before you choose the unlocked version, ask us about the options. Description of the variants: description of ECU variants.
Questions and answers
| Will the car start straight away once the 06J906026FK 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 a matching start of the VW number enough? |
| No. The final letters denote a specific version – always compare the full number. |
| What details should I send before ordering the unlocked version? |
| The numbers from the label of your current ECU or a clear photo of it. Based on these, we will check which unlocking methods are possible. |
| 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. |
