Detailed Product Overview

When an expansion valve begins to fail, refrigerant metering can become inconsistent and cabin cooling performance can drop. This URO replacement is designed for Mercedes-Benz applications including the SL500, SL600, S500, S600, E320, 190E, and other listed models, with coverage across 1984-2002 vehicles. The valve is engineered to match OE dimensions and handle the pressure and temperature demands of automotive air conditioning systems. Part number 1408300484 is also referenced for service and catalog lookup.

This part cross-references VEMO V30-77-0017 for the same application.

What It Helps Fix

• Weak or uneven cabin cooling
• Incorrect refrigerant flow through the evaporator circuit
