Air Suspension Valve Block 4N0616013A For Audi A8 A6 S8 A7L RS6

Constituent Structure of Valve Block

• Solenoid valve: Control the inflow or outflow of air, which is controlled by the electronic control unit (ECU) through signal instructions.

• Gas connection: A passage connecting an air source, such as an air compressor, to an air spring.

• Height sensor interface: Receive signals from the vehicle's height sensor to determine the amount of adjustment required.

• Pressure sensor: Measure the air pressure in the system to ensure safe operation.

Main Function

1. Height control: Based on the feedback signal from the height sensor, the distribution valve adjusts the air pressure in the air suspension to keep the vehicle at a predetermined height, regardless of how the load inside the vehicle changes.

2. Pressure distribution: The distribution valve is responsible for distributing the compressed air to the different air springs, ensuring the left and right or front and rear balance of the vehicle.

3. Automatic adjustment: When the vehicle is starting, driving or stopping, the distribution valve can detect changes in the height of the body in real time and automatically make adjustments.

4. Fault protection: Modern air suspension distribution valves are usually equipped with a fault diagnosis function. When a system anomaly occurs, the distribution valve can take emergency measures, such as locking a certain height to ensure basic vehicle availability.
