Audi car air conditioning vents may produce abnormal noise due to several different reasons. Here are the specific causes: Abnormal noise in the air conditioning duct: The air filter has not been replaced for a long time, or there are foreign objects such as leaves in the duct. Abnormal noise from the air conditioning compressor: Poor heat dissipation of the air conditioning system or blocked pipelines can cause compressor noise. Excessive internal pressure in the compressor can reduce its service life, so immediate action is required. Component failure: Failure of the generator or the tensioner bearing of the air conditioning belt, or loss of the automatic belt adjustment function of the tensioner, resulting in abnormal noise.

Do new cars come with a safety hammer?

Generally, new cars do not come with a safety hammer, and you need to purchase one separately. Below is the relevant information: 1.
