Overview - Heater
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2022 Audi SQ5, 2022 Audi Q5 e, 2022 Audi Q5, 2021 Audi SQ5, and 2021 Audi Q5 e. However, it is still accessible from the selected car via links, so may be relevant.
- There are different versions and manufacturers of the heater and A/C unit. Individual components of the different heater and A/C units are similar but not the same. Interchanging components from different manufacturers is not permitted.
- The heater on a vehicle without an A/C system is the same as the heater and A/C unit on vehicles with a "Low" A/C system. The evaporator installed in the heater is without function, here it functions only as a place holder and to reduce noise.
- The expansion valve -C- is installed on a vehicle without an A/C system only to seal the pass-through in the grommet to the vehicle interior.
- The connections on the expansion valve (for the A/C system refrigerant lines) are connected on vehicles without an A/C system with a closure cap -A- (tightening specification of the nut -B- 8 Nm).
- The layout and the removing and installing of the different components of the heater is the same as on a heater and A/C unit of a "Low" A/C system.
- Removing and installing the heater is the same as on a "Low" A/C system heater and A/C unit. Naturally, the components that are only installed on the A/C system are omitted (emptying and filling the refrigerant circuit, removing and installing the refrigerant lines from the expansion valve).
