What are the maintenance items for an Audi Q5 at 120,000 kilometers?

Audi Q3 120,000-kilometer major maintenance items are as follows: Engine oil change: Changing the engine oil is a routine task for both minor and major maintenance, and the 120,000-kilometer maintenance is no exception. Engine oils include mineral oil, semi-synthetic oil, and fully synthetic oil, with quality increasing in that order. Transmission fluid change: During the 120,000-kilometer maintenance, changing the transmission fluid is a crucial item. The transmission is the link between the clutch and the driveshaft, with very precise internal gears. Frequent gear shifting can easily cause the transmission fluid to deteriorate, which then fails to provide cooling and lubrication, making the transmission more susceptible to damage. Therefore, it is recommended to change the transmission fluid according to the maintenance manual. Coolant change: The replacement interval for car coolant is generally two years, which aligns well with the 120,000-kilometer major maintenance cycle. Coolants usually come in two colors: pink and blue. Since the cost of coolant is not high, it is advisable to replace it as per the car's maintenance manual.

Is It Serious If a Car Engine Has Air Leakage?

It is still possible to drive a car with an engine air leak. However, if the intake pipe leaks, it may suck in dust, sand, or other debris from the outside, leading to increased wear on the cylinder walls or piston rings. An engine air leak can cause abnormal idling and signal irregularities. Any air leakage in the engine will result in unstable operation and insufficient power under various working conditions. Methods for checking air leakage: 1. Visual Inspection: The observation method is the simplest and most intuitive way to detect issues. When the engine shows symptoms, make full use of observation to check if there are faults in the cylinders and spark plugs. If the spark plug electrodes have excessive carbon deposits and are wet with engine oil, it indicates poor piston ring sealing causing oil leakage. 2. Repeated Testing: Infer the location of the fault by testing and observing different outcomes. Check the pressure in the cylinders to understand the cause of the problem based on pressure changes. For example, use a pressure gauge to measure the pressure. If the pressure rises significantly, it indicates piston ring wear. If the pressure remains unchanged, it suggests air leakage from the valves or cylinder gasket. 3. Experience Comparison: This method is more suitable for experienced car owners who can roughly deduce the cause after comparing throttle responses.

Can I call 112 for vehicle removal?

You cannot call 112 for vehicle removal. You can dial 122 instead. 122 is a department established by China's public security traffic management authorities to handle public traffic accident reports, dispatch police officers to deal with various alerts and assistance requests, and also accept public reports, complaints, and inquiries regarding traffic management and traffic police law enforcement. In such cases, the traffic police can be utilized to address situations where someone intentionally refuses to move their vehicle. Alternatively, you can use Alipay's "One-Click Vehicle Removal" feature. Open Alipay, find "City Services," click on "One-Click Vehicle Removal," enter the license plate number and location, and submit. The other vehicle owner will then receive a call notification from the "Traffic Management 12123" system. You can also call 114. 114 cannot directly provide the owner's phone number, but by providing the license plate number and location of the vehicle that needs to be moved to the operator, your call will be directly transferred to the other owner's mobile phone without revealing their number. After dialing 114, provide the license plate number, and 114 will transfer the call to the owner. To better protect the owner's privacy, the owner's phone number is only transferred, not disclosed. However, there is a prerequisite: the owner must apply to China Unicom to bind their mobile phone number to their license plate number and activate this service.

When reversing into a parking space, if the left side is wider, which way should I turn the steering wheel?

When reversing into a parking space, if you see from the rearview mirror that the left side is wider, turn the steering wheel to the left to adjust the distance between both sides to be roughly equal. If the right side is wider, turn the steering wheel to the right until the distances on both sides are similar. The principle of turning the steering wheel towards the wider side when reversing means: 1. Taking left-side reversing as an example, if you notice that the distance between the car and the left edge of the parking space is too large, turn the steering wheel to the left. If the distance between the car and the left edge is too narrow, immediately turn the steering wheel to the right to correct the position and ensure the car enters the space properly. 2. For right-side reversing, observe the right rearview mirror to monitor the distance between the car body and the right edge of the parking space while reversing. If the distance between the car and the left edge is too large, turn the steering wheel to the left; if the distance between the car and the left edge is too narrow, immediately turn the steering wheel to the right. 3. Again, taking left-side reversing as an example, during the reversing process, the car body will form an angle with the parking space. Observe the left rearview mirror to check the width and distance between the car body and the edge of the parking space.

How often should the fuel filter of Audi Q5 be replaced

Audi Q5 fuel filter should be replaced after driving 40,000KM or 42 months, whichever comes first. If not replaced in time, it will not be able to filter impurities and other functions. Over time, it will cause insufficient fuel supply and insufficient power of the car engine. If the filter is found to be very dirty before reaching the above mileage, it also needs to be replaced. It should be noted that when replacing the fuel filter, the car's engine oil, oil filter, and air filter should also be replaced. After installation, it is necessary to develop the habit of checking the sealing of the interface to avoid oil leakage. The fuel filter is referred to as the fuel filter. There are carburetor type and electronic injection type fuel filters. For gasoline engines using carburetors, the fuel filter is located on the inlet side of the fuel pump, with low working pressure, and generally uses a nylon shell. For electronic injection engines, the fuel filter is located on the outlet side of the fuel pump, with high working pressure, and usually uses a metal shell. The filter element of the fuel filter mostly uses filter paper, and some use nylon cloth or polymer materials. The main function of the fuel filter is to filter impurities in gasoline. If the fuel filter is too dirty or blocked. In-line filter paper fuel filter: Inside this type of fuel filter, folded filter paper is connected to both ends of the plastic or metal filter. After the dirty oil enters, it passes through layers of filter paper from the outer wall of the filter to the center, and clean fuel flows out.
