Detailed Description

The Arnott VB-3951 is an air suspension solenoid valve block that routes compressed air from the compressor to the air struts or air springs. Over time, valve block O-rings can dry out and leak, while moisture exposure can damage the solenoid electronics. When that happens, the suspension system may lose pressure control and the compressor may cycle more often than normal. This replacement valve unit is built for specific-fit applications and is intended for vehicles such as the 2003-2009 Mercedes-Benz E320, 2006-2009 Mercedes-Benz E350, 2003-2009 Mercedes-Benz E500, 2007-2009 Mercedes-Benz E550, 2007-2011 Mercedes-Benz CLS550, and 2003-2012 Maybach 57 and 62. This part cross-references URO 2113200158 for the same application. The Arnott VB-3951 part number is also commonly searched by owners servicing Mercedes-Benz E-Class and CLS-Class air suspension systems.

Common Problems This Part Can Help Address

• Air leaks caused by worn valve block O-rings
• Compressor overworking from pressure loss in the suspension circuit
• Moisture-related solenoid electrical faults
• Uneven or inconsistent air suspension height control
• Slow suspension response during air distribution

Installation Notes and Tips

Verify connector shape, terminal count, port count, and mounting points before installation. This is a specific-fit component, so confirm vehicle application by year, make, and model before ordering. Inspect the surrounding air lines, fittings, and compressor condition during replacement to help prevent repeat failures. Professional installation is recommended for air suspension service on Mercedes-Benz and Maybach vehicles.

Quality Assurance

Arnott manufactures this valve block with quality materials selected to match OE-level performance expectations. The VB-3951 is built as a direct replacement for the original valve block used in select Mercedes-Benz and Maybach air suspension systems.
