Are you having trouble with the heat on your Mercedes W123? The Mercedes W123 240D 300D 300TD 280E monovalve is notoriously unreliable. Recently Bosch discontinued the 0008302984 Mercedes W123 monovalve for 240D 300D 300TD etc. 

Our complete replacement kit eliminates the need for the Mercedes W123000830 2984 and replaces it with an easy-to-install and high flow vacuum actuated valve. Our new setup provides for faster control response, providing a more comfortable experience for your passengers. Because our newer valve is "high-flow" the coolant circulator pump is no longer necessary. 

Mercedes W123 240D 300D 300TD 0008302984 Monovalve Retrofit Kit Includes:

-OE type Pierburg vacuum solenoid made in Germany.
-Durable, high flow vacuum controlled heater valve with external control arm for verification of operation and long life.
-OE style semi-rigid polyamide vacuum supply and vent lines.
-All necessary vacuum elbows, silicone vacuum hose, and vacuum tees for conversion.
-New heater hose for associated components.
-Genuine Mercedes electrical connector and terminals for electrical connection.
