This used Audi OEM blower motor (part 8K1820021C) is the genuine HVAC fan removed from a donor vehicle. It also replaces 8K1820021B and 8K1820021A. The blower motor/fan circulates cabin air; a failing unit often causes weak airflow or a whining noise. Fits engine options including 2.0T, 3.0 supercharged, and TDI variants.
