Audi AC Climate Control / Temp Unit (OEM 4B0820043AH) — a used genuine part from a donor vehicle. This unit manages the automatic climate control system, regulating cabin temperature and fan speed. When it fails, you may experience inconsistent temperature output, stuck blend doors, or the AC system blowing only hot or cold air regardless of settings. It was originally installed in Audi A6, A6 Quattro, and Allroad Quattro models with 2.7L turbo, 2.8L, or 4.2L V6/V8 gas engines.
