Parts for your 2020 Audi Q5-Heater tap

Understanding the Heater Tap in the 2020 Audi Q5

If you're looking into the heating system of the 2020 Audi Q5, you might come across the term heater tap and wonder if this part is relevant or even present in this model. The straightforward answer is that the 2020 Audi Q5 does not utilise a traditional heater tap. This might seem confusing at first, especially if you are used to hearing about heater taps in older or simpler automotive heating systems.

A heater tap is a valve that controls the flow of engine coolant into the heater core. In many older vehicles, this valve allowed the driver to regulate the amount of hot coolant passing through the heater core, which in turn adjusted how warm the cabin would get. It's a mechanical part designed to stop or allow coolant flow, somewhat like a gatekeeper to the vehicle's heating system.

However, modern vehicles including the 2020 Audi Q5 often use more advanced systems that do not require a heater tap. Instead of a simple tap for coolant flow, the Q5 features an electronically controlled climate control system. The temperature regulation happens primarily through electronic blend doors inside the HVAC (heating, ventilation, and air conditioning) system, which mix hot and cold air to achieve the desired cabin temperature.

This setup means the heater core in the 2020 Audi Q5 is almost always fed with a steady stream of coolant, which is constantly heated by the engine's cooling system. The temperature changes the occupants feel inside the vehicle come from the careful blending of this warm air with cooler air rather than by mechanically controlling coolant flow to the heater core.

Given this system design, the heater tap is not used because it's essentially rendered obsolete by the advances in electronic climate control. The 2020 Audi Q5's system is more precise, faster to respond, and offers a higher level of comfort and convenience than what a mechanical heater tap could provide.

This also means maintenance and servicing are different. Instead of checking or replacing a heater tap, technicians focus on maintaining the entire HVAC system - ensuring the electronic controls, blend doors, and climate sensors are all functioning properly. Coolant maintenance remains important too, because the heater core relies on warm coolant, but the regulation of air temperature is not mechanical.

By moving away from mechanical taps to electronic air control, Audi improves reliability. Mechanical taps can wear out, become stuck, or leak, leading to uneven heating or coolant loss. The modern electronic system avoids these problems and provides a better overall ownership experience for drivers of the 2020 Q5.
