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 038906018GM ECU fit my Octavia 1.9 TDI?
Yes, if your unit carries the VW number 038906018GM or the Bosch number 0 281 010 181. This used, fully working ECU from an Octavia 1.9 TDI is available locked or unlocked.
Engine Control Unit Skoda Octavia 1.9 TDI Bosch 038906018GM 0281010181
If an Octavia 1.9 TDI will not start or will not connect to the diagnostic tool, the engine control unit may be to blame. This Bosch unit has the number 0281010181 and the VW number 038906018GM. It controls injection and turbo boost and checks immobiliser authorisation when the engine is started. Before you order, compare the numbers on the label on your unit's casing.
Numbers to compare
- 038906018GM – VW/Skoda part number
- 0281010181 – Bosch number (label: 0 281 010 181)
The GM and GN versions differ by just one letter, but they are different ECUs – the letter indicates the software or hardware version. Check the number 038906018GM carefully.
What points to a faulty unit?
- the starter turns but the engine will not fire,
- the car goes into limp mode by itself,
- no injection control even though the injectors are working,
- corrosion or signs of moisture on the ECU connector.
It is a good idea to read the fault memory and check wiring continuity first – sometimes the loom is to blame, not the unit.
Locked or unlocked?
There are two options to choose from. The locked unit still holds the data and immobiliser of the car it came from – this option is for workshops that will unlock, program and match the unit themselves. The unlocked unit is prepared by us before dispatch, usually within 1–2 working days.
The preparation method depends on the part number, software and immobiliser, so PIN / CAR PASS, Virgin, IMMO OFF, auto programming or cloning are not always possible. Before buying, ask us what can be done for 038906018GM. Details: ECU preparation options.
