To replace the cabin heating radiator in the Audi A3, open the glove compartment to access the screws that secure it from the inside and outside. Remove the panel, the carpet underneath it, and the side panel of the footwell on the passenger side.

Behind this panel, you will find the cabin heating radiator, which needs to be disconnected from the pipes and connectors so it can be extracted from its housing. You can then install a new one by refitting all the previously removed parts.
