Heater Control Valve - Repair or Replace
A heater control valve diverts hot water (coolant, or antifreeze) from the radiator into the heater core in your vehicle’s cabin, resulting in soothing warm air. If your heat has stopped working, your 2003 Audi TT may require a replacement heater control valve.
