The reasons why the Audi A4 air conditioner only blows air but does not cool are as follows: 1. Lack of refrigerant in the car air conditioner: The car air conditioning system consists of multiple metal pipes with small gaps between them, leading to slight refrigerant leakage. Additionally, the drying bottle in the car air conditioning system absorbs moisture, which compresses some of the refrigerant. When the refrigerant level drops to a certain point, the cooling capacity of the car air conditioner decreases. 2. The car air conditioner compressor belt is too loose: When the belt driving the car air conditioner compressor is loose, the compressor slips during operation, resulting in reduced compressor speed and decreased refrigerant delivery, leading to the air conditioner not cooling. 3. The condenser of the air conditioner is too dirty: The main purpose of the condenser is heat dissipation, and a dirty condenser affects the heat dissipation effect. 4. The air conditioner filter has not been maintained or cleaned: A dirty filter affects the airflow, which in turn affects the cooling performance of the air conditioner.

What to Do When There's Abnormal Noise Upon Releasing the Accelerator?

When abnormal noise occurs upon releasing the accelerator, you should first check whether it is due to a cold start, inappropriate engine oil, or a backfire fault in the engine. Here are the detailed explanations: 1. Abnormal noise during cold start: When starting a cold engine, the oil pump cannot immediately establish oil pressure, causing insufficient lubrication of the valves and resulting in abnormal noise. After the car has been parked for a long time, the engine oil flows back to the oil pan. During a cold start, the oil pump cannot immediately establish oil pressure, especially in the upper part of the engine, leading to insufficient lubrication of the valves. The hydraulic lifters and mechanical rocker arms fail to operate properly, causing abnormal noise. Solution: Reduce the number of times the car is turned off. 2. Abnormal noise caused by inappropriate engine oil: If the engine oil viscosity is too high, it may not provide sufficient lubrication, leading to abnormal noise. Solution: Replace with the required gasoline.

How to Deal with Rust Spots on the Car Body?

The methods for dealing with rust spots on the car body are as follows: 1. Clay bar: You can use a clay bar to scrub the car body surface during washing. A clay bar is a paint-safe material that can remove stubborn stains from the car body surface. To remove rust spots on white car paint, you need to rub back and forth vigorously several times until clean. 2. Polishing: If the clay bar cannot remove rust spots on white car paint, you can use polishing to eliminate them. Polishing can also remove minor scratches on the car body. 3. Touch-up paint: When the above two methods fail to remove rust spots on white car paint, you can lightly sand the area and then use white touch-up paint to dab a small amount of paint. 4. Preventive measures for rust spots: Wash the car frequently, apply protective measures for the paint such as waxing, sealing, coating, or ceramic coating. Avoid parking under trees, as many trees secrete sap that is difficult to remove from the car. Also, wash the car immediately after rain, as 90% of rust spots on the car body are caused by acidic substances in rainwater.

Can a New Car with a Manufacturing Date Over 6 Months Be Accepted?

Vehicles with a production date exceeding 6 months are considered inventory cars. Due to prolonged storage, these inventory cars may experience issues such as degraded engine oil, battery depletion, premature paint deterioration, damp electronic components, and aging rubber parts. Continuing to drive such vehicles can significantly reduce their service life. Therefore, purchasing a brand-new car is more reliable. Below are methods to identify inventory cars: 1. Check the production date: Vehicles with a manufacturing date over half a year can be identified as inventory cars. 2. Inspect tire rubber for aging: Inventory cars stored outdoors are prone to rubber aging due to exposure to high temperatures, sun, and rain, as are other rubber components (wiper blades, sunroof seals, etc.). 3. Examine the chassis: Before purchasing, request the 4S store staff to lift the vehicle and check for shock absorber oil leaks and rust on the exhaust pipe and muffler.
