Where is the air suspension distribution valve located on the Audi A8?

The air suspension distribution valve is generally located on the engine. The working principle of the air pump is as follows: The engine drives the air pump crankshaft via two V-belts, which in turn drives the piston to pump air. The pumped air is directed through pipelines into the air storage tank. Simultaneously, the air storage tank channels the stored air through another pipeline into the pressure regulator valve fixed on the air pump, thereby controlling the air pressure inside the storage tank. Introduction to the air valve: An apparatus used to either remove air from a sealed space or add air to it. Air pumps are categorized into electric air pumps, manual air pumps, and foot-operated air pumps. Electric air pumps utilize electricity as their power source, continuously compressing air to generate air pressure.
The air suspension distribution valve on the Audi A8 is usually hidden under the trunk. You can find it by lifting the floor mat in the trunk, located near the spare tire well or the small central area of the chassis. Its function is to control the flow of compressed air into each suspension airbag, keeping the car level and preventing bumps. If the valve gets clogged or leaks due to aging, the suspension may wobble, the warning light will turn on, and driving safety will be affected. I recommend not attempting to disassemble it yourself—have a professional shop inspect the air lines to avoid injury from high-pressure air. When driving, avoid scraping the undercarriage, and park away from damp areas to prevent rust. This component is ingeniously designed but prone to damage if not properly maintained. Address issues promptly to avoid more serious failures.
The distribution valve of the Audi A8 is usually found at the bottom of the trunk. Lift the carpet, and you can see the component next to the spare tire. It controls the airflow to the shock absorbers, ensuring the stability of the vehicle body. Once, while driving, the suspension warning light came on due to an air leak in this part, causing the car to tilt to one side and making it difficult to control. After sending it for repair, it was found that the valve had aged and was replaced, solving the issue. It's recommended to regularly check the pipeline connections at the 4S shop and avoid driving on bumpy roads for extended periods to prevent wear and damage to the valve body, which is a core component of the suspension system.
