• Direct replacement air suspension solenoid valve block
• Specific-fit design for confirmed Audi applications
• 6-port valve block layout
• 1 female oval connector with 3 pin terminals
• Built with upgraded O-rings and electrical components
• Designed to meet or exceed original equipment standards

How the Valve Block Works

The air suspension solenoid valve block routes compressed air from the compressor to the air struts or air springs. When the internal seals dry out or the electrical solenoids degrade, the system can lose pressure control and force the compressor to work harder. Arnott VB-4339 is engineered as a direct OE-style replacement for those failure points on Audi air suspension systems, including rear applications on models such as the Audi A6 Quattro, A7 Sportback, A8 Quattro, and RS6 Avant.

This part cross-references Audi 4N0616013 and 4N0616013A for the same application.

Common Problems This Part Can Address

• Air leaks caused by worn or dry-rotted valve block O-rings
• Compressor overwork from pressure loss in the suspension circuit
• Slow or uneven air spring or air strut operation
• Moisture-related electrical solenoid issues inside the valve block
• Suspension height control faults tied to valve block failure

Installation Notes

Verify connector style, port count, and vehicle application before installation. This unit uses a pin terminal layout, a single female oval connector, and a 6-port configuration. Because fitment varies by model year and position, confirm the exact Audi application in the fitment list before replacing the original valve block. Professional installation is recommended for air suspension repairs to ensure proper sealing and system calibration.

Quality Assurance

Arnott manufactures this valve block using quality materials selected to meet or exceed original equipment expectations. The VB-4339 is built as a standard-grade replacement for Audi air suspension systems where reliable air routing and electrical control are required.
