Heater, Removing And Installing

WARNING: This page is about a different car, the 2021 Audi S4 and 2021 Audi A4 Quattro. However, it is still accessible from the selected car via links, so may be relevant.

The removal and installation is largely identical to the heater and A/C unit. Refer to FRONT HEATER AND A/C UNIT .

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).
