To change the heater core on an Audi TT, you'll need to start by draining the coolant and removing the dashboard, which involves disconnecting various electrical components and removing bolts. Next, access the heater core by removing the HVAC housing, then disconnect the hoses and remove the old heater core. Install the new heater core, reassemble the HVAC housing, reconnect the hoses, and reassemble the dashboard before refilling the coolant and checking for leaks. Always refer to a repair manual for specific details and safety precautions.
