Arnott VB-3499 Air Suspension Solenoid Valve Unit

Arnott VB-3499 Air Suspension Valve Block

Arnott VB-3499 is a new air suspension solenoid valve block for Mercedes-Benz air suspension systems. It is a direct OE replacement for the 2006-2012 Mercedes-Benz R-Class (W251) and is built to restore proper air distribution between the compressor, air springs, and air struts.

For Mercedes-Benz R350, R320, R500, R550, and R63 AMG applications, this valve block addresses common wear-related air leaks and control issues that can develop as original O-rings dry out or internal solenoids are affected by moisture.

Key Features

• Arnott NEW product line air suspension solenoid valve unit
• Direct OE replacement for the factory valve block
• Specific fitment for select Mercedes-Benz air suspension applications
• 3-pin terminal design with 3 connectors and 3 ports
• Male rectangular connector configuration
• Standard grade replacement with hardware included
• Cross-reference: Mercedes-Benz 2513200158

Product Details

The Arnott VB-3499 valve block controls how compressed air is routed through the suspension system. In normal operation, it distributes air from the compressor to the air springs and air struts so ride height and suspension response remain consistent. When the original block begins to leak or the solenoids degrade, the compressor may cycle more often and the system can lose pressure control. VB-3499 is engineered as a direct replacement for the OE unit on the Mercedes-Benz R-Class platform.

This part number, VB-3499, is also referenced for Mercedes-Benz OE part number 2513200158. It is a specific-fit component, not a universal valve block, and should be matched to the vehicle’s suspension configuration before installation.

Common Problems This Part Can Address

• Air leaks caused by dried or damaged valve block O-rings
• Compressor overwork from repeated pressure loss
• Moisture-related solenoid performance issues
• Uneven air distribution to the suspension corners
• Suspension warning lights or height-control faults related to valve block failure

Installation Notes

Confirm the vehicle’s suspension layout before ordering, especially on models noted as not suitable for vehicles with front air suspension. Verify connector style, port count, and OE part number match before installation. Clean the air lines and surrounding fittings during replacement to reduce the chance of contamination entering the new valve block. After installation, clear any stored suspension fault codes and check the system for leaks and proper ride-height operation.

Quality Assurance

Arnott’s NEW line is positioned as a direct OE-style replacement for factory air suspension components. VB-3499 is built for specific vehicle fitment and follows the original connector and port layout used on the application listed above.
