Here are the reasons why the Polo's air conditioning is not cooling: 1. Lack of refrigerant. 2. Dirty condenser. The following are symptoms indicating the need to add refrigerant: 1. Usage exceeding 5 years. 2. The external unit fan does not blow hot air in summer. 3. Frost formation on the high-pressure pipe (thin pipe) in summer. 4. Ice formation or mist blowing from the internal unit in summer. 5. The thick pipe at the external unit's copper pipe connection does not feel hot to the touch in winter. Below is additional information about car air conditioning: 1. Car air conditioning includes cooling devices, heating devices, and ventilation devices. 2. This integrated system makes full use of the limited space inside the car, featuring a simple structure and easy operation, making it a popular modern car air conditioning system internationally.

What Causes a Motorcycle Spark Plug to Flood?

Motorcycle spark plug flooding can be caused by: 1. Improper operation: Prolonged use of the choke while riding can lead to spark plug flooding; 2. Overly rich air-fuel mixture; 3. Engine oil burning issues. Solutions for motorcycle spark plug flooding: 1. Check if the engine has oil burning problems; 2. Inspect the air filter, clean the carburetor, and properly adjust the carburetor's air-fuel mixture, main jet needle position, and lower the float level. The spark plug is a crucial component of a gasoline engine's ignition system. It introduces high-voltage electricity into the combustion chamber, causing it to jump across the electrode gap and generate a spark, thereby igniting the combustible air-fuel mixture in the cylinder. A spark plug mainly consists of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell, with the side electrode welded to the shell.

What Causes the Squeaking and Friction Noise in the Steering Wheel of a New Car?

The reasons for the squeaking and friction noise in the steering wheel of a new car are: 1. Friction between plastic components; 2. The clock spring in the steering wheel; 3. Noise from the stabilizer bar. The steering wheel is a wheel-shaped device used to control the direction of cars, ships, and airplanes. Its function is to convert the force applied by the driver to the edge of the steering wheel into torque and transmit it to the steering shaft. Precautions for using the steering wheel: 1. Do not place your hands too close together on the steering wheel; 2. The amplitude and speed of steering wheel rotation should match the turning angle of the car and the vehicle's speed; 3. When the car is stationary, avoid turning the steering wheel to prevent damage to the steering system and tire wear; 4. On different roads, the grip strength on the steering wheel should vary—hold it firmly but not too tightly. When adjusting direction, use gentle force, make small and quick adjustments.

What is the fault when the ESP light is on in an Audi A6?

Audi A6 ESP light on indicates a fault in the Electronic Stability Program system. The ESP system is a general term for systems or programs designed to enhance vehicle handling performance while effectively preventing loss of control when the vehicle reaches its dynamic limits. Whenever the ESP system detects a discrepancy between the driver's input and the actual movement of the vehicle, it immediately stabilizes the vehicle through selective braking or engine intervention. The Audi A6 is a mid-to-large-sized car under FAW-Volkswagen Audi. Taking the 2004 Audi A6 2.8L Technology Leader as an example, its dimensions are 4886mm in length, 1810mm in width, and 1475mm in height, with a wheelbase of 2850mm. The body adopts a 4-door, 5-seat sedan structure, with a fuel tank capacity of 70 liters, a curb weight of 1560kg, and a trunk capacity of 487 liters.

What Causes High Radiator Temperature but Fan Not Spinning?

Reasons for high radiator temperature but fan not spinning: 1. The thermostat is functioning properly, the upper and lower water pipe temperatures are consistent, but the fan does not spin—possibly due to a faulty coolant temperature sensor; 2. The fan itself is damaged; 3. Poor contact in the fan power supply wiring; 4. Low coolant level in the radiator; 5. A faulty thermostat. The radiator is part of the car's cooling system, typically consisting of an inlet tank, outlet tank, header, and radiator core. Most car radiator fans operate via electronic temperature control, meaning the fan only starts spinning when the engine coolant reaches the required temperature. If the temperature is too low, the radiator fan will not spin. Therefore, when encountering a non-spinning fan issue, the first step should be to check whether the coolant temperature meets the required threshold.
