How to Replace the Heater Radiator in an Audi A3?

Model: Audi A3 8V, MK 3 - Years 2012-2019
Part: Heater core

To replace the cabin heater radiator in an Audi A3, open the glove compartment and completely unscrew its internal fixing screws. This will allow you to 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 heater radiator, which must be disconnected from pipes and connectors so that it can be extracted from its housing. This will allow you to install a new replacement part, reassembling all previously removed components.
