LANDNOVO 2123200358 Air Suspension Solenoid Valve Block for Mercedes-Benz ML/GL/R/S-Class, CLS & E-Class | Premium OE Replacement

LANDNOVO — Precision in Motion. Engineered by GB.

Brand New – 100% Original Equipment Performance.

Is your Mercedes-Benz ML, GL, R-Class, S-Class, E-Class, or CLS sitting unevenly, sagging, or displaying an Airmatic suspension warning light? The culprit is often a failed air suspension solenoid valve block. The LANDNOVO 2123200358 Air Suspension Solenoid Valve Block is a brand new, premium replacement engineered to restore your vehicle's air distribution and ride height control.

Manufactured to OE specifications, this valve block delivers 100% original equipment function, performance, and durability. It is a complete drop-in replacement for the original unit (OE 2123200358 / A2123200358 / 2513200058 / A2513200058 / 2123200658 / 2123200158) and is designed to distribute air from the compressor to each air spring and air strut with precision.

What Does the Air Suspension Solenoid Valve Block Do?

The air suspension solenoid valve block is the central control unit of your Mercedes-Benz Airmatic suspension system. It is responsible for distributing pressurized air from the compressor to each individual air spring or air strut, based on commands from the suspension control module[reference:0]. This precise distribution allows the vehicle to maintain proper ride height, level the chassis under varying loads, and adapt to changing road conditions in real time.

Over time, the O-rings inside the valve block can dry rot and leak air, causing the compressor to overwork or allowing moisture to degrade the electrical solenoid components[reference:1]. A failing valve block can lead to sagging suspension, uneven ride height, slow raising and lowering times, and premature compressor failure.

Symptoms of a Failing Valve Block

• Vehicle sagging – one or more corners sit lower than normal
• Uneven ride height – the vehicle sits unevenly from side to side
• Slow raising or lowering – the suspension takes longer than usual to adjust
• Compressor running constantly – the system tries to compensate for air leaks
• Airmatic warning light – the dashboard displays a suspension system warning
• Hissing noise – audible air leak from the valve block area

Installation Tips

• Professional installation highly recommended.
• Before installation, inspect all air lines and fittings for cracks, kinks, or other damage.
• Ensure the air suspension system is properly depressurized before removing the old valve block.
• After installation, the air suspension system should be professionally tested for leaks using diagnostic equipment.
• Inspect related components including the air compressor, air springs, and ride height sensors for wear or damage.
• Important: When replacing the air suspension compressor, always replace the relay before installing the new compressor, even if it seems to still work. This is a specification by the car manufacturer.
