The automatic transmission control unit (often designated as TCU or TCM) is a crucial electronic component responsible for smooth and trouble-free gear shifting. Its failure, most often caused by overheating, short circuits, or water damage, results in jerking, an inability to shift gears, or the vehicle entering limp mode. Purchasing a new module at an authorized dealership is a massive expense, which is why replacing it with a fully functional, used original is the most reasonable solution.

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.

How can I check whether the 06A906033CL ECU will fit?
Read the label on your current ECU: the VW/Skoda number should read 06A906033CL and the Continental number 5WP40429 04. If so, this used, fully working unit from a petrol Octavia 1.6 is the right replacement.
Engine Control Unit Skoda Octavia 1.6 Continental 06A906033CL 5WP4042904
This unit was made by Continental, which took over the 5WP numbering from Siemens VDO. The ECU was fitted to a Skoda Octavia 1.6 with a petrol engine, where it handled fuel metering, ignition and idle control. In the Skoda parts system, it has the number 06A906033CL. It is used, fully working and in good condition.
Markings on the casing
- 06A906033CL – VW/Skoda number
- 5WP4042904 – Continental number; shown on the label as 5WP40429 04
The suffix "CL" in the number 06A906033CL is the version identifier – for the software or the electronics. Another variant from the same series may have different software, so choose a replacement by the full number.
What to look out for when diagnosing
- the engine warning light is on and internal ECU fault codes are stored,
- the engine only starts after several attempts, or not at all,
- the idle speed fluctuates or the engine stalls when braking,
- no communication with the engine module on the tester.
First measure the ECU supply voltage and check that the earth leads are not corroded.
Unlocked or locked version?
You can order each unit in two ways. We send the locked unit with the data and immobiliser of the previous Octavia; your garage carries out the unlocking, programming and adaptation. With the unlocked version, we do the work – we prepare the ECU before dispatch, usually within 1–2 working days.
The possible preparation method (PIN / CAR PASS, Virgin, IMMO OFF, auto-programming, clone) depends on the part number, software and immobiliser, so please ask us before you buy. See also: engine control unit variants.
Questions and answers
| Siemens or Continental – does it matter? |
|---|
| The 5WP numbering was used by Siemens VDO and later by Continental. What counts is that the numbers 06A906033CL and 5WP4042904 match. |
| Does the 06A906033CL ECU need programming after fitting? |
| The locked version requires programming and adaptation. With the unlocked one, it depends on the agreed preparation method. |
| What condition is the unit in? |
| It is a used part, fully working and in good condition. You will find the warranty period in the product specifications table. |
