VW ID4/ID6 Steering column lock/Ignition immobilizer module –  1EA905861

The VW ID.4/ID.6 Steering Column Lock/Ignition Immobilizer Module with part number 1EA905861 is an important component of the vehicle’s ignition system and anti-theft system. This part combines two critical functions: steering column locking and ignition immobilization, both of which are designed to protect the vehicle from unauthorized use or theft.

Steering Column Lock:

• The module is responsible for locking the steering column when the vehicle is turned off and the key is removed (or when the vehicle is in the “off” position). This is a common anti-theft feature that prevents the steering wheel from turning, making it more difficult for thieves to drive the car away.
• When the vehicle is started, the module electronically releases the steering lock, allowing the steering wheel to move freely for normal driving.

Ignition Immobilizer:

• The ignition immobilizer is a critical security feature that prevents the vehicle from starting without the correct key or key fob. This system ensures that only authorized keys (those with the correct transponder chip) can start the vehicle.
• The immobilizer works by verifying the identification code from the key or key fob with the vehicle’s Engine Control Unit (ECU) or immobilizer module. If the code matches, the engine will start; if not, the system will prevent the vehicle from starting, protecting it from theft.

Anti-Theft Protection:

• The combination of the steering column lock and ignition immobilizer forms an effective anti-theft system. Without the proper key or key fob, both the steering column remains locked and the engine will be immobilized, making it very difficult for thieves to bypass the system and drive the car away.

Integration with Other Systems:

• The steering column lock/ignition immobilizer module works in conjunction with other vehicle security systems, such as the central locking system and keyless entry system. These systems are often integrated with the vehicle’s ECU or body control module to ensure proper operation of the vehicle’s security features.
