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:

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 28SA4486 on the 038906012AN ECU mean?
28SA4486 is the Bosch software number. The EDC15UM+ ECU also carries the VW number 038906012AN and the Bosch number 0 281 010 107 – it comes from a Skoda Fabia 1.9 SDI and is used and fully working.
Engine Control Unit Skoda Fabia 1.9 SDI Bosch EDC15UM+ 038906012AN 0281010107
The Fabia 1.9 SDI with the naturally aspirated diesel uses a Bosch ECU from the EDC15UM+ family. The label on this unit shows three numbers: VW 038906012AN, Bosch 0281010107 and the software number 28SA4486. The unit controls fuel metering and starting.
Numbers on the label
- 038906012AN – VW/Skoda part number
- 0281010107 – Bosch number, shown on the label as 0 281 010 107
- 28SA4486 – Bosch software number
- EDC15UM+ – ECU family
When matching, the most important number is the VW number with the AN suffix. The software number 28SA4486 helps confirm the version if two ECUs have similar markings.
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.
How we prepare the ECU for dispatch
If you want a unit that is ready to fit, choose the unlocked option – we prepare it before the parcel goes out, which usually takes 1–2 working days. Workshops with their own coding equipment often prefer the locked option: it keeps the data and immobiliser of the previous car, and the technician does the unlocking, programming and matching.
The available methods – PIN / CAR PASS, Virgin, IMMO OFF, auto programming or cloning – vary depending on the part number, software version and immobiliser. Get in touch before ordering and we will confirm the option for this unit. More on the ECU preparation options page.
