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 1Z0907115 / 0261S02114 ECU fit an Octavia 2.0 Turbo?
It fits if your unit has the same VW number, 1Z0907115 – with no letter at the end – and Bosch number 0 261 S02 114. This used, fully working MED9.1 ECU comes from a 2006 Octavia 2.0 Turbo.
Engine Control Unit Skoda Octavia 2.0 Turbo Bosch MED9.1 1Z0907115 0261S02114
What sets the number 1Z0907115 apart is that it has no version letter at the end – this is the base version of this ECU. The unit is a Bosch MED9.1, a Motronic ECU for petrol direct-injection engines, fitted to a 2006 Octavia 2.0 Turbo. It manages injection, ignition and boost pressure. It is used, fully working and in good condition.
Numbers to check
- 1Z0907115 – VW/Skoda part number, without a version letter
- 0261S02114 – Bosch number, shown on the label as 0 261 S02 114
- MED9.1 – Bosch ECU family
ECUs numbered 1Z0907115A, B and so on are different versions. If the number in your car ends in a letter, look for a unit with the same suffix.
Possible symptoms of a fault
- no boost and limp mode,
- difficult starting or no start,
- intermittent communication with the unit during diagnostics,
- high-pressure fuel fault codes that keep returning despite repairs.
First check the fuses, earths and the wiring loom running to the ECU – these are quick and inexpensive steps.
How to choose the ECU variant
We prepare the unlocked variant in-house before dispatch, which usually takes 1–2 working days. Not all methods are always possible – PIN / CAR PASS, Virgin, IMMO OFF, auto-programming and clone depend on the part number, software and immobiliser. Ask before you buy what can be done with this unit.
We send the locked variant with the data and immobiliser of the previous Octavia. It suits garages that will unlock, program and adapt the ECU themselves. See: engine control unit variants.
