Arnott VB-4337 Air Suspension Solenoid Valve Unit - Rear

Arnott VB-4337 Rear Air Suspension Valve Block

Restore proper air distribution in the rear suspension with the Arnott VB-4337 air suspension solenoid valve unit. This direct replacement is built for specific applications and uses quality O-rings and electrical components to address common valve block failures in Audi, Porsche, and related rear air suspension systems.

Key Features

• Direct replacement air suspension solenoid valve block
• Specific fit for rear suspension applications
• Pin terminal type with 1 female oval connector
• 3 terminals and 7 ports for system routing
• Built with upgraded O-rings and electrical components
• Standard grade replacement for OE-style service
• Part number VB-4337 for easy identification

Detailed Description

The Arnott VB-4337 valve block controls how compressed air is routed from the compressor to the air struts or air springs. When the internal O-rings dry out or leak, the compressor can run longer than normal and moisture can damage the solenoid components. This replacement valve block is engineered to meet or exceed original equipment expectations for rear air suspension service on vehicles such as the Porsche Taycan, Porsche Panamera, Audi e-tron GT, and Audi RS e-tron GT.

This part cross-references 971616056 and 971616056B for the same application. Use VB-4337 when replacing a failing rear air suspension solenoid valve unit on supported Audi and Porsche platforms.

What It Helps Fix

• Rear suspension air leaks caused by worn valve block O-rings
• Compressor overwork from pressure loss in the valve assembly
• Slow or uneven air delivery to air struts or air springs
• Moisture-related solenoid electrical issues
• Suspension height control problems tied to valve block failure

Installation Notes and Tips

Verify the connector style, terminal count, port count, and rear position before installation. This is a specific-fit component, so match the vehicle application carefully on Porsche Panamera rear air suspension, Porsche Taycan rear air suspension, and Audi e-tron GT rear applications. Inspect air lines, seals, and related suspension components for contamination or wear before installing the new valve block.

Quality Assurance

Arnott manufactures this solenoid valve block with quality materials selected to match OE-level function and durability. The VB-4337 is intended as a direct replacement for the original rear valve block on supported applications.
