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.

What does the number 3T0907115 on a Bosch MED17.5 ECU mean?
3T0907115 is the VW/Skoda part number assigned to this unit, and 0261201795 (on the label 0 261 201 795) is the Bosch number. Together they identify a used, fully working MED17.5 ECU for a petrol Skoda.
Engine Control Unit Skoda Bosch MED17.5 3T0907115 0261201795
The MED17.5 family belongs to Bosch's Motronic engine control units – the letter D in MED stands for petrol direct injection. Unit 3T0907115 calculates the fuel quantity, ignition timing and throttle operation based on sensor signals. It comes from a Skoda with a petrol engine; we do not specify the model, because matching is decided by the numbers.
Identifying the unit
- 3T0907115 – VW/Skoda part number
- 0261201795 – Bosch number, as on the label: 0 261 201 795
- MED17.5 – Bosch Motronic ECU family with direct injection
The MED17.5 type alone is not enough to find a match, as this family comes in many software versions. Compare both the VW number and the Bosch number with the label.
Symptoms of a faulty MED17.5 ECU
- the engine will not start and the direct injectors receive no signal,
- the throttle does not respond and the car goes into limp mode,
- communication faults with the engine unit on the CAN bus,
- damage after a battery was connected with reversed polarity.
Before ordering a replacement unit, measure the supply voltage and check the earths and connectors – faults there produce similar error codes.
How to choose the ECU version
We offer the unit in an unlocked version – prepared before dispatch, usually within 1–2 working days – and a locked version with the previous vehicle's data and immobiliser. The latter is chosen by garages that unlock, program and adapt ECUs themselves.
PIN / CAR PASS, Virgin, IMMO OFF, auto programming, cloning – which method is feasible depends on the part number, software and immobiliser. Please contact us before ordering. All the options are described on the ECU preparation options page.
