1 Answers
Regarding the reasons and solutions for the hissing sound when the Audi A6 air conditioner is turned on, the following are detailed: 1. System malfunction: The abnormal noise in the air conditioner is often due to moisture or air in the system's refrigerant. Solution: Replace the refrigerant. 2. Compressor electromagnetic clutch issue: Since the compressor frequently operates under high load, transitioning from low to high speeds, the demands on the electromagnetic clutch are high. Additionally, the electromagnetic clutch is installed close to the ground and often comes into contact with rain and dirt. When the bearings inside the electromagnetic clutch are damaged, abnormal noise occurs. Solution: Inspect and repair the compressor.
