Detailed description

SCG0406 is engineered as an OE-quality replacement for hydraulic suspension systems that rely on stable fluid circulation. Rein builds this hose assembly with OE rubber compound hose, zinc alloy coated carbon steel tubing, and OE-spec crimped connections to match the original design intent. It is a practical choice for Mercedes-Benz CL-Class and S-Class vehicles that need a replacement for the low-pressure line between the active suspension pulsation damper and tee. This part cross-references Genuine 2203200753 and 2209978182 for the same application.

Common repair concerns

• Hydraulic fluid seepage from aged hose material.
• Corrosion at tubing or end fittings.
• Loss of hydraulic pressure in the suspension circuit.
• Degraded hose flexibility from heat and age.
• Fitment issues caused by worn original connections.

Installation notes and quality

Confirm the vehicle’s hydraulic suspension routing before installation and inspect adjacent lines, brackets, and sealing points for wear. Rein recommends regular hydraulic fluid service for ABC systems, and the manufacturer notes that fluid condition directly affects system life. This part is leak tested to over 2000 PSI and includes a 24-month/24,000-mile warranty.
