How It Works

The valve block controls how air is distributed from the compressor to the air springs and air struts on BMW air suspension systems. When the internal O-rings dry out or the solenoids are affected by moisture, the system can lose pressure control and place extra demand on the compressor. Arnott VB-3787 restores proper air routing for BMW 5 Series GT and 7 Series applications, including BMW 535i GT, 750Li, and ActiveHybrid 7 models.

This part cross-references WABCO 4722555610 and BMW 37206784137 for the same application.

Common Problems It Can Address

• Air leaks at the valve block
• Compressor running too often or for too long
• Uneven ride height from poor air distribution
• Moisture-related solenoid issues
• Loss of air suspension pressure control

Installation Notes

Confirm the connector style, terminal count, and port layout before installation. This is a specific-fit BMW air suspension solenoid valve unit, so matching the vehicle’s WABCO OES configuration is important. Inspect the compressor, air lines, and surrounding seals for contamination or wear before installing the new valve block.

Quality Assurance
