★ Top Answer
The AudiA3's heater control valve is located on the heater core. A key sign of a malfunctioning heater control valve is the absence of warm air from the heater. When the valve breaks or becomes stuck, it may limit or stop the flow of coolant to the heater core. The lack of coolant flow to the heater core results in the heater being unable to generate warm air for the interior. Another common indicator of a heater control valve problem is coolant seepage, as the valve may wear out or develop cracks over time. Additionally, leaks can occur due to excessive corrosion from exposure to aged or contaminated engine coolant.
