What causes high low pressure and normal high pressure in the Audi C7's air conditioning system?

Audi C7 air conditioning system exhibiting high low pressure and normal high pressure is typically caused by a faulty or damaged expansion valve. Here are the specific details about the expansion valve: 1. Symptoms of a clogged expansion valve: When the car's air conditioning is turned on, it fails to cool properly. Measuring the pressure in the air conditioning lines with a pressure gauge will show excessively high high pressure and excessively low low pressure, indicating expansion valve failure. 2. Symptoms of a damaged expansion valve: The low-pressure pipe doesn't feel cold to the touch, the dryer and condenser may frost over, both high and low pressures become abnormal, and the high-pressure pipe temperature becomes irregular. 3. Function of the expansion valve: The expansion valve serves as a throttling device. High-temperature, high-pressure liquid refrigerant passes through the expansion valve's throttle orifice, becoming low-temperature, low-pressure mist-like hydraulic refrigerant, creating conditions for refrigerant evaporation.

Is the car film applied on the inside or outside?

Automotive window film should be applied to the inside of the car glass. If applied to the outside, it is prone to erosion by wind and frost, leading to faster aging and reduced service life. The following are the functions of window film: 1. Automotive window film refers to applying a thin film-like substance to the front and rear windshields, side windows, and sunroof of a vehicle. This film is also called solar film or explosion-proof and heat-insulating film. 2. Its main functions are to block ultraviolet rays, partially block heat, and prevent injuries caused by sudden glass breakage. At the same time, based on the one-way perspective performance of the solar film, it achieves the purpose of protecting personal privacy. 3. In addition, it can also reduce the damage to items and people inside the car caused by ultraviolet radiation, and to some extent, achieve the effect of saving fuel consumption. 4. Reduce air conditioning energy consumption. Applying heat-insulating film can compensate for the loss of air conditioning cooling capacity, instantly lowering the temperature inside the car, thereby achieving a certain degree of fuel savings.

Will the Audi A4L particulate filter get clogged?

Audi A4L particulate filters can get clogged. When the accumulated particulates reach a certain level, the particulate filter will automatically ignite to burn and expel them, which is known as the 'regeneration' process of the particulate filter. The general procedure for cleaning the particulate filter using cleaning equipment is as follows: First, remove the particulate filter and place it on the testing equipment. Then, use the probe on the equipment to check the clogging condition of the particulate filter. Next, preheat the cleaning equipment to 300°C, place the particulate filter inside, and adjust the temperature to 600°C for oxidation treatment of the carbon deposits. After the treatment is completed, cool the particulate filter and then use a high-pressure blowing tool for cleaning. Once the cleaning is done, use professional measuring equipment to record the data of the particulate filter. After completing the above steps, reassemble the particulate filter and install it back into the vehicle.

What is the emission standard for a 2004 vehicle?

The emission standard for 2004 vehicles is China II (National Standard II). There are several ways to check your vehicle's emission standard: through the environmental protection label issued during vehicle inspection, by inquiring at the vehicle management office, or by checking the vehicle model catalog information on the Motor Vehicle Environmental Protection Network. Below are the methods to check your vehicle's emission standard: 1. The simplest and most direct way is to look at the vehicle's environmental protection label, which has clear markings on the back (however, environmental protection labels have not been issued since 2017). 2. Log in to the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center to inquire. 3. Bring the original or a copy of the vehicle registration certificate to the vehicle management office for inquiry (this is the most accurate method). 4. For new vehicles, you can check the vehicle's factory certificate. However, the vehicle certificate is usually kept at the vehicle management office. Therefore, when purchasing a new car, it is recommended to make a copy for future reference. 5. Make a rough judgment based on the year the vehicle was registered.

What type of engine oil should be used for Audi Q2L maintenance?

Audi Q2L maintenance uses 5W-40 or 5W-30 engine oil. The following are the specific details of car maintenance items: 1. Engine oil and oil filter replacement: Mainly for the maintenance of the lubrication system. The primary function of the lubrication system is to effectively lubricate various components of the car engine to prevent excessive wear. The oil filter's function is to remove various impurities from the engine oil to ensure the normal operation of the lubrication system. The oil filter should be replaced along with the engine oil during an oil change. Under normal circumstances, the car should be serviced every 5,000 kilometers. 2. Filter element replacement: The air filter element filters the air before it enters the cylinder, removing impurities, dust, sand, and other foreign objects. The cleaning and maintenance of the air filter element depend on the usage environment. The gasoline filter element is usually replaced after driving 20,000 kilometers. 3. Spark plug replacement: Spark plugs are consumable parts and should be replaced every 20,000 kilometers. In addition, components such as brake fluid, transmission oil, battery, throttle, fuel injector, and brake pads are all inspection items during routine maintenance, and their maintenance should be carried out based on usage conditions.
