To remove the heater from a 2003 Audi A6, first disconnect the battery and drain the coolant. Then, remove the dashboard and center console to access the heater core. Disconnect the heater hoses from the core, unbolt the mounting brackets, and carefully pull the heater core out of the housing. Reassemble in reverse order, ensuring all connections are secure and the system is properly refilled with coolant.
