Restore your Mercedes‑Benz ride level with this direct‑fit Air Suspension Solenoid Valve Block. When the factory valve develops a fault, your SUV’s chassis can sag, trigger persistent suspension warning lights, or deliver a harsh, uneven ride. This replacement unit takes over pressure regulation exactly where the original part mounts, bringing smooth damping back to every corner. Engineered from a reliable rubber, steel, and aluminum blend, it handles repeated air cycling without warping or developing slow leaks.

Benefits & Tips

  • Silence dashboard alerts – Installing a fresh valve block clears common suspension error codes and lets the self‑leveling sensors recalibrate accurately.
  • Balance dual systems – Models equipped with twin air compressors usually get longer life when you swap both valve blocks simultaneously to match wear cycles.
  • Settle the ride fast – Park the vehicle on level ground overnight after installation so the air bags fully deflate and establish even floor clearance.

Specifications

  • Function – Centralized air pressure distribution for automatic height control.
  • Construction – Rubber seals bonded to steel brackets and an aluminum housing core.
  • OEM cross‑references – A2123200358, 1663200204, A251320005, 2123200358.
  • Unit weight – 0.75 kilograms per block.

Package includes:

  • One (1) Air Suspension Solenoid Valve Block assembly.

Installation reminder: Always disconnect the negative battery terminal before unplugging the electrical connector. Inspect nearby air lines for dry rot while the old unit is out, and torque mounting bolts to manufacturer spec to prevent vibration noise over time.
