It fits a wide range of Mercedes models (CL, CLS, GL, GLE, GLS, ML, R, S classes) across model years listed below and replaces OEM numbers including 2123200358. The unit helps restore reliable air routing when the original valve block has leaks, failed solenoids, or electrical faults.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this valve block restore proper suspension function?\u003c\/h3\u003e\n\u003cp\u003eThe valve block receives pressurized air and uses internal solenoids and ports to route that air to individual air struts. When a circuit fails, air leaks or a solenoid stops switching, the system can’t hold height — replacing the valve block resolves those distribution faults. Installation returns controlled air flow to each wheel so the car can level and the ECU can manage height corrections.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSix ports: compressor feed, four air spring outlets, and reservoir connection\u003c\/li\u003e\n  \u003cli\u003eDirect-fit replacement for listed Mercedes part numbers\u003c\/li\u003e\n  \u003cli\u003eRestores sealed air routing to prevent slow leaks and uneven ride height\u003c\/li\u003e\n  \u003cli\u003eWorks with the vehicle’s existing harness and ECU signals\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this part fit my Mercedes model and year?\u003c\/h3\u003e\n\u003cp\u003eThis Humoony valve block matches a long list of Mercedes variants — verify compatibility with the vehicle’s model code and year.
