Arnott VB-4336 Air Suspension Solenoid Valve Unit

BMW Air Suspension Valve Block Replacement

The Arnott VB-4336 air suspension solenoid valve unit is a direct replacement for a failing BMW valve block. It is built with quality O-rings and electrical components to meet or exceed original equipment standards for BMW air suspension systems.

Compatible With BMW 750i, 750Li, 760Li, 760i, X5 without front air suspension, 745i, 745Li, 525i, 530i, 540i, and 528i applications across the listed model years.

Key Features

• Direct replacement air suspension solenoid valve block
• Specific fit design for the listed BMW applications
• Blade terminal type with 3 terminals
• 2 female connectors with rectangular connector shape
• 3 ports for air distribution from the compressor
• Standard grade construction using quality sealing and electrical components
• Arnott part number VB-4336 for easy identification

How It Works

The valve block routes compressed air from the compressor to the air struts or air springs. On BMW air suspension systems, worn O-rings can dry out and leak, while moisture and age can damage the solenoid electrical components. Replacing the valve block restores proper air routing and helps maintain consistent suspension operation. This part cross-references BMW 37221092349 and 37226778773 for the same application.

Common Problems It Can Help Solve

• Air leaks caused by deteriorated valve block O-rings
• Compressor overwork from repeated air loss in the suspension system
• Slow or uneven air spring or air strut inflation
• Electrical solenoid faults inside the original valve block
• Suspension performance issues on BMW air suspension-equipped vehicles

Installation Notes

Verify connector style, terminal count, and port layout before installation. This is a specific-fit component, so confirm vehicle application by year, make, model, and suspension configuration. Professional installation is recommended for BMW air suspension repair to ensure proper sealing and system function.

Quality Assurance

Arnott manufactures this valve block as an OE-style replacement using quality materials selected for air suspension service. The VB-4336 is engineered to meet or exceed original equipment requirements for the listed BMW applications.
