Individual variants may differ in price
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.

The engine control unit 0280800344 (0085459732) is a proven component that helps restore proper and stable engine operation in the Mercedes W124 200E.
Below you will find short information about the engine control unit with part numbers 0280800344 and 0085459732, used in the Mercedes W124 200E.
This ECU is used in the Mercedes W124 200E with a 2.0 petrol engine. Part numbers 0280800344 and 0085459732 refer to the same engine control module. To ensure correct fitment, it is best to confirm compatibility using the vehicle VIN.
Yes — both numbers refer to the same engine control unit. The only difference is the way the numbers are listed in Bosch and Mercedes catalogs. If the numbers match, the ECU is interchangeable and fits vehicles with the same engine configuration.
The most common symptoms include starting problems or uneven engine operation. The car may lose power or show diagnostic errors despite working sensors. Sometimes there is no diagnostic communication with the ECU. These symptoms often indicate an ECU issue.
In older models like the W124, Bosch ECUs do not always require immobilizer programming, but in some cases it is recommended to match ECU parameters with the vehicle. This should be done by an automotive electronics specialist. After proper adaptation, the module works correctly.
