What's the problem with the Audi Q5's air conditioning not cooling after running for half an hour?

The reasons why the Audi Q5's air conditioning stops cooling after running for half an hour are as follows: Insufficient or too little refrigerant: A common reason for car air conditioning not cooling is insufficient or too little refrigerant, which is likely due to minor leaks. Solution: You can observe through the sight glass on the top of the dryer. During normal operation of the air conditioning, if there are continuous slow bubbles in the sight glass, it indicates insufficient refrigerant. If obvious bubble flipping occurs, it means the refrigerant is severely insufficient. Excessive refrigerant: Too much refrigerant can also cause the air conditioning not to cool, as the proportion of refrigerant in the air conditioning system is strictly required. If the proportion is too high, it will affect heat dissipation. Similarly, adding too much cooling oil during maintenance can also reduce the heat dissipation of the system. Solution: Observe through the sight glass on the dryer. If no bubbles are seen in the sight glass during operation and none appear after the compressor stops, it definitely indicates excessive refrigerant. If the pressurized cooling oil is excessive, you will see relatively turbid bubbles in the sight glass during normal operation. Loose drive belt of the car air conditioning compressor: Car cooling relies on refrigerant, and refrigerant transmission depends on the air conditioning compressor, with the drive belt being a crucial moving part. If the drive belt is loose, the compressor may slip during operation, reducing transmission efficiency and compressor speed, thereby decreasing refrigerant delivery and causing the air conditioning not to cool. If the compressor drive belt is too loose, it should be tightened. If it cannot be turned by hand, it means the belt is too tight and should be slightly loosened.
