Audi A4 A5 A6 CDN EA888 Gen2 Aircond Compressor 8K0 260 805 L - Used Original Parts

Diagnosis and Common Symptoms

The air conditioning compressor in the Audi A4, A5, and A6 (CDN/EA888 Gen2) is a variable displacement unit that often encounters mechanical fatigue or control valve failure. Technicians frequently see fault codes such as B108C (A/C Control Valve) or B10AE (High Pressure Sensor) when the system fails. Primary symptoms include the vents blowing ambient air while the vehicle is at a standstill, audible metallic grinding or "whirring" noises from the engine bay, and a noticeable lack of cooling despite the A/C button being engaged. If the compressor internal swash plate seizes, it can also lead to increased drag on the serpentine belt, causing premature wear on the tensioner.
