  • Open uri20150716 11956 18kl8kv

Part number 4B3121411 is a brand new, unused Genuine Audi/Volkswagen hvac heater control valve.

The heater control value is simply a control valve used to control the quantity of hot coolant entering your car's heater core. By turning on your interior fan, air passes over the heater core (like a mini radiator) and your car's interior becomes warmer. A faulty valve can leak coolant or be stuck (full hot, full cool, or anywhere in between), and must be replaced for driver comfort.
