    Choose the Correct ECU Engine Control Unit Variant

    Not every ECU Engine Control Unit can be prepared in every available version. The available preparation method depends on the ECU manufacturer, vehicle model, immobilizer system and software version.

    Important: Please contact us before placing your order.
    We will verify your ECU part number and help you choose the correct preparation method for your vehicle.

    Email: contact@auto24parts.com

    Available ECU Preparation Variants

    1. Locked ECU

    This version is intended mainly for workshops and automotive electronics specialists. The ECU still contains immobilizer data and configuration from the previous vehicle.

    Before installation in another vehicle the ECU must be unlocked and programmed using professional diagnostic equipment.

    2. Unlocked ECU

    Depending on the ECU model and vehicle, different preparation methods are available. Not every ECU supports all options, therefore we recommend contacting us before purchasing.

    The ECU can be prepared in one of the following versions:

    a) ECU with PIN Code (CAR PASS)

    The ECU includes the original PIN (CAR PASS). After installation, the ECU must be reset, the PIN code entered and the immobilizer programmed using a compatible diagnostic tool.

    b) Virgin ECU

    A Virgin ECU has been cleared of all previous vehicle data and restored to factory-default status. After installation it must be programmed and adapted to the vehicle using professional diagnostic equipment.

    This is the standard preparation method for many ECUs when no other option is selected.

    c) Plug & Play (IMMO OFF)

    The immobilizer function is disabled inside the ECU. After installation, the engine can operate without standard immobilizer programming.

    Availability depends on the ECU model and software version.

    d) Plug & Play (AUTO PROGRAMMING)

    After installation, the ECU automatically adapts itself to the vehicle. No manual coding or programming is required under normal operating conditions.

    e) Plug & Play (CLONE)

    Your original ECU is cloned to another identical working unit. Immobilizer information, coding and configuration are copied so the replacement ECU can be installed without additional programming.

    Clone service requirements:

    The original damaged ECU must be sent to us. It should still allow data reading through diagnostic communication or direct memory access. If the required data cannot be recovered, cloning may not be possible.

    3. Complete Plug & Play Kit

    The complete kit includes the ECU together with the immobilizer components required to start the vehicle. Depending on the vehicle, the kit may include the ECU, immobilizer module, ignition lock, key, transponder, BSI or BCM module.

    All supplied components must be installed in the vehicle.

    Important Information

    • Available preparation methods depend on the ECU hardware and software version.
    • Not every ECU supports Virgin, IMMO OFF, AUTO PROGRAMMING or CLONE preparation.
    • Virgin ECUs require programming after installation.
    • Clone service requires the original ECU.
    • Preparation may extend dispatch time by approximately 1–2 business days.
    • Please send your ECU part number or a clear label photo before ordering.

    How to Choose the Correct ECU Variant?

    Simply send us the complete ECU part number or a clear photo of the ECU label. We will verify whether your controller can be prepared as Virgin, IMMO OFF, AUTO PROGRAMMING, CLONE or supplied as a complete Plug & Play kit.

    Tip: The ECU part number is much more important than the vehicle model alone. Always provide the complete Bosch, Siemens, Continental, Delphi, Magneti Marelli or Denso numbers whenever possible.

    • Burnt Automatic Transmission Control Module – Symptoms, Diagnosis, and an Effective Solution

      The automatic transmission is an incredibly complex system, combining advanced mechanics, hydraulics, and precise electronics. The brain of this entire operation is the transmission control module, commonly known as the TCM. In fractions of a second, this device analyzes data from speed sensors, throttle position, and engine RPM to make decisions about the perfect moment to shift gears.

      Unfortunately, due to harsh working conditions, these modules can be prone to serious failures. One of the most critical faults is the physical burning of the electronics inside the module. In the following article, we will take a closer look at this phenomenon, discuss the characteristic symptoms, and advise on the most cost-effective way to deal with this expensive problem.

    • Burnt ABS Pump Controller: Failure Symptoms and Why You Should Choose an Original Used Part

      The ABS (Anti-lock Braking System) is the foundation of active safety in every modern vehicle. Its main task is to prevent the wheels from locking during sudden braking, allowing the driver to maintain full control over the car in emergency situations. The brain of this entire system is the electronic controller, which is most often integrated with the hydraulic ABS pump.

      This device processes data from wheel speed sensors in fractions of a second and decides when to open and close the solenoid valves. Unfortunately, like any advanced electronics, this controller is prone to failure. One of the most serious issues is the complete burning out of the module. Learn how to recognize this fault, why you should avoid non-original aftermarket replacements, and how to permanently solve the problem.
