Arnott VB-3427 Air Suspension Solenoid Valve Unit

Arnott VB-3427 Air Suspension Valve Block

Arnott VB-3427 is a new air suspension solenoid valve block for Mercedes-Benz vehicles with factory air suspension. It replaces the failing OE valve block that controls air distribution from the compressor to the air springs and air struts on the Mercedes-Benz S-Class (W222) and Maybach applications.

Built as a direct replacement, this valve block addresses common air management faults caused by aging seals and moisture exposure. It is a specific-fit component for 2014-2020 Mercedes-Benz S-Class and 2016-2020 Maybach models, including AMG and Hybrid variants, where equipped.

Key Features

• Direct replacement air suspension solenoid valve block
• Specific-fit design for Mercedes-Benz air suspension systems
• 5-port, 5-connector configuration with oval male connector
• 3-terminal pin layout for OE-style electrical connection
• Standard-grade replacement with hardware included
• Cross-reference: Mercedes-Benz 0993200058
• Part number VB-3427 for ordering and identification

Detailed Description

The Arnott VB-3427 valve block regulates compressed air flow to the suspension system, helping maintain proper ride height and air spring operation. Over time, valve block O-rings can dry out and leak, which can cause the compressor to run excessively or allow moisture to affect the solenoid components. This replacement is intended for Mercedes-Benz S-Class, Maybach, and related models listed in the fitment data, including 2014-2020 Mercedes-Benz S-Class W222 applications and 2016-2020 Maybach models. If you are searching for a Mercedes-Benz S-Class air suspension valve block replacement or a VB-3427 air suspension solenoid valve unit, this part matches the OE application requirements.

Arnott’s NEW product line focuses on replacement suspension components for vehicles with factory air systems, and VB-3427 follows that approach with a direct-fit valve block for the listed Mercedes-Benz applications.

What It Helps Address

• Air leaks caused by worn valve block O-rings
• Compressor overwork from pressure loss in the suspension circuit
• Moisture-related solenoid degradation
• Uneven or unstable air spring pressure control
• Faults tied to a failing OE air suspension valve block

Installation Notes

Verify the connector style, terminal count, and port layout before installation. This part uses a pin terminal type, 5 connectors, 5 ports, and a male oval connector shape. Confirm vehicle fitment by model year and, where listed, VIN break information before replacing the original valve block. For 2015 Mercedes-Benz S500 and S550 applications, the fitment note specifies compatibility from VIN A005153 and up.

Fits 2014-2020 Mercedes-Benz S63 AMG, 2015-2020 Mercedes-Benz S65 AMG, 2014-2017 Mercedes-Benz S550, 2014-2020 Mercedes-Benz S-Class W222 variants listed in the fitment data, and 2016-2020 Mercedes-Benz Maybach models where equipped with air suspension.

Quality Assurance

Arnott supplies replacement suspension components engineered for OE-style fit and function. VB-3427 is a new replacement part built to match the listed Mercedes-Benz air suspension applications and OE cross-reference 0993200058.
