What is the refrigerant charging capacity for the Audi Q7?

When adding refrigerant, a pressure gauge is first used for testing, and it should be charged up to 2.5 pressure. Below are the methods for adding refrigerant to a car: 1. High-pressure side charging: This involves adding refrigerant from the bypass port (multi-purpose channel) of the compressor discharge valve (high-pressure valve), known as high-pressure side charging, where liquid refrigerant is added. This method is characterized by safety and speed, suitable for the first charging of the refrigeration system, i.e., after leak detection and vacuuming. However, it must be noted that the compressor should not be turned on during charging (with the engine off), and the refrigerant canister must be inverted. 2. Low-pressure side charging: This involves adding refrigerant from the bypass port (multi-purpose channel) of the compressor suction valve (low-pressure valve), known as low-pressure side charging, where gaseous refrigerant is added. This method is characterized by slower charging speed and can be used for supplementing refrigerant in the system.

What is the optimal age and mileage for a used car?

The optimal age for a used car is within 5 years, and the mileage should be under 50,000 kilometers. Below are some related introductions about used cars: 1. Optimal age and mileage: The optimal age is within 5 years, as environmental regulations are being upgraded rapidly, and annual inspection standards are becoming stricter. If the new car's market value is below 200,000, then the mileage should ideally be under 50,000 kilometers; if the new car's market value is between 200,000 and 700,000, then a mileage under 100,000 kilometers is still acceptable in terms of performance. 2. Considerations when purchasing: Check the brand and model—here, the model refers to the vehicle's specific type. Some brands are easier to maintain, with more available and cheaper spare parts, making such used cars more convenient for future use. Also, consider the price drop of the new car. If the new car's price is relatively stable and the price drops slowly, the used car's resale value will be higher.

What are the gear positions of Audi?

Audi gear positions include P, N, D, R, and S. The following is a related introduction to Audi gear positions: 1. P position: It is the parking and starting position. When this gear is engaged, the parking lock mechanism locks the transmission output shaft. 2. R position: It is the reverse gear. When this gear is engaged, the hydraulic system reverse gear oil circuit is connected, causing the drive wheels to reverse for reverse driving. When the vehicle is not completely stopped, do not forcibly shift to the "R" position, as this may damage the transmission. 3. N position: It is the neutral gear. When the neutral gear is engaged, the planetary gear system idles and cannot output power. 4. D position: It is the drive gear, also known as the forward gear. When the gearshift lever is in this position, the hydraulic system control device automatically connects the corresponding forward gear based on the throttle signal and vehicle speed signal. It can automatically shift up or down with changes in driving speed, achieving automatic transmission function. 5. S position: It is the sport mode. When the gearshift lever is in this position, the transmission control module receives the driver's command, and the vehicle enters sport mode.

Why does the car automatically shut off when stopping?

The following are the reasons why a car automatically shuts off when stopping: 1. Misoperation: Especially for beginners, such as shifting to the wrong gear, braking too hard, improper clutch-throttle coordination, or accidentally turning off the car with the key. Simply restart the engine. 2. Dirty throttle/idle speed control valve: This mostly occurs at idle speed, often accompanied by engine shaking. Lightly press the accelerator when restarting to provide fuel for ignition. It is recommended to clean the throttle promptly. 3. Fuel system failure: Causes include poor fuel quality, running out of fuel, fuel pump burnout, clogged fuel lines, faulty fuel pump fuse, or defective fuel pressure sensor. Inspect related components. 4. Ignition system failure: Includes spark plug issues, faulty ignition coil/module, or aging cylinder wires. Check related components. 5. Throttle or idle speed control valve failure: These are critical components of the engine intake system and relatively precise parts. Many cases of engine stalling or failure to start are due to damaged throttle assemblies or idle speed control valves.
