- Description:
Genuine Audi Heater Core for your Audi, OEM part number 8E1-820-031, is a precision-engineered component designed to deliver consistent cabin heating and defrost performance for the Audi A4, S4, and RS4, including Cabriolet variants. Also referred to as an HVAC heater core or heatercore, this unit functions as a small radiator mounted within the dashboard, circulating hot engine coolant through its fins to transfer heat into the passenger cabin. When this component fails or develops leaks, you may notice fogged windows, a sweet coolant smell inside the vehicle, or complete loss of heat — all signs it needs immediate replacement. Choosing a genuine Audi OEM heater core over an aftermarket alternative matters significantly for this part. Heater cores must integrate precisely with the HVAC housing, coolant lines, and airflow channels specific to these models. Aftermarket versions frequently use thinner tubing and lower-grade aluminum alloys that are prone to premature pinhole leaks and reduced heat transfer efficiency. The genuine 8E1820031 meets Audi's exact dimensional and metallurgical specifications, ensuring a leak-free seal and long-term thermal performance without compromise. Whether you're searching for an Audi S4 RS4 A4 OEM heater core or simply part number 8E1-820-031, Audi Henderson is an authorized Audi dealer offering this genuine part backed by the manufacturer's warranty.
