How to Replace the Heating Radiator in an Audi A3

Model: Audi A3 MK 2, 8P - Years 2003-2013
Part: Heater core

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.
