Arnott VB-3831 Air Suspension Valve Block

The Arnott VB-3831 is a direct replacement air suspension solenoid valve block for select Audi, Bentley, and Volkswagen vehicles with factory air suspension. It routes compressed air from the compressor to the air springs and air struts, helping restore proper ride-height control and system response.

Built as a specific-fit replacement, this valve block addresses common OE valve block wear that can lead to air leaks, compressor strain, and moisture-related solenoid issues. It is a practical solution for Audi A6, Audi A8 Quattro, and Audi Allroad Quattro air suspension repair work.

Detailed Description

The VB-3831 is an OE-style air suspension valve block that manages air distribution from the compressor to the suspension air springs and air struts. Over time, valve block O-rings can dry out and leak, while moisture intrusion can affect the electrical solenoids inside the unit. Replacing the valve block can restore proper air routing and reduce unnecessary compressor cycling on vehicles such as the Audi A6, Audi A8 Quattro, and Audi Allroad Quattro.

This part cross-references Audi 4F0616013 and 4Z7616013 for the same application.

What It Helps Fix

• Air leaks at the suspension valve block
• Compressor running too often or for too long
• Uneven or inconsistent air spring inflation
• Slow suspension height changes
• Moisture-related solenoid performance issues

Installation Notes and Tips

Verify connector style, port count, and vehicle fitment before installation. Inspect air lines, seals, and surrounding suspension components for wear or contamination when replacing the valve block. After installation, clear any stored suspension fault codes and confirm the system reaches and holds the correct ride height.

Quality Assurance

Arnott supplies this VB-3831 as a replacement valve block for factory air suspension systems on select Audi, Bentley, and Volkswagen models. It is built to match the specified OE application and restore proper air distribution function.
