A used genuine OEM AC compressor from an Audi, part number 4N0816803. This is the factory compressor for the 48-volt mild hybrid system, serving both the 3.0L turbo V6 and 4.0L turbo V8 MHEV engines. When the compressor fails, the most common symptom is a loss of cold air from the vents, often accompanied by a clicking or grinding noise from the belt-driven clutch. It also supports the hybrid battery thermal management.
