Audi A4 steering gear failure reasons are as follows: Heavy steering failure causes: The power steering system contains a large amount of air, leading to abnormal car steering; Foreign objects in the steering hydraulic pipeline cause the steering pump flow control valve to stick; Loose connections in the power steering system result in steering fluid leakage; Excessive wear of the steering gear piston cylinder, poor oil seal sealing, or control valve sticking or damage. Abnormal noise during steering causes: Overloading of the steering system leads to excessive wear of the stator and rotor inside the steering pump, causing irregular movement of the oil in the pump and producing abnormal noise; Loose installation of the steering gear or pump on the bracket, internal wear of the steering gear, and improper adjustment of the gear and rack.

How many months at most can a car's annual inspection be overdue?

There is no concept of postponement or exceeding the time limit for motor vehicle annual inspections. No matter how many days past the deadline, it is considered illegal. However, it depends on the situation. If it is only overdue within the month of the inspection date, generally there is no issue and you can participate in the annual inspection normally. If it exceeds one month past the inspection date, it is considered an illegal act of missing the inspection. Consequences of overdue annual inspection penalties: 1. Relevant regulations: According to the regulations, if a vehicle does not undergo the annual inspection within the specified time, the public security authorities will impose a warning and a fine of 200 yuan. If caught by traffic police on the road, a fine of 200 yuan and 3 demerit points will be imposed. 2. Insurance companies will not compensate: If a car does not undergo the annual inspection on time and is involved in a traffic accident during operation, the party involved will bear full responsibility, and the insurance company will not provide compensation. 3. Forced scrapping: If a car does not undergo safety technical inspections for three consecutive years and fails to obtain the motor vehicle inspection qualification mark, it will be subject to forced scrapping.

What is the reason for no internet connection on BMW's in-car WiFi?

The reason for no internet connection on BMW's in-car WiFi is either the mobile phone has insufficient balance or the vehicle is parked in an area with poor signal. Below are the relevant explanations: 1. Insufficient mobile phone balance: It is necessary to confirm whether the mobile phone being used has insufficient balance, resulting in the inability to use data traffic normally. In-car WiFi provides certain convenience for drivers while driving, thereby enhancing the driving safety of the vehicle. 2. Poor signal in the parking area: The lack of internet connection on BMW's in-car WiFi may be due to poor signal in the area where the vehicle is parked. You can try again in a different location, or you can turn off the vehicle's infotainment system and mobile phone and then reconnect.

How to Practice Driving Without a Sense of Direction?

Practice techniques for driving without a sense of direction: 1. Gentle steering: When adjusting the direction of the vehicle, steer gently and smoothly. Pay attention to the conditions behind and in front of the vehicle, making slight adjustments with small angles to gradually correct the driving direction. 2. Avoid abrupt or fast movements: Never change the vehicle's direction too abruptly or quickly while driving. For example, if the vehicle is initially tilting to the right, an overly aggressive adjustment might cause it to tilt to the left or even cross the road edge line, leading to test failure. During high-speed driving (e.g., in the third driving test), adjust the vehicle's direction by turning the steering wheel just two or three finger-widths, preferably in several small steps. 3. Posture: Sit upright and straight while driving, look far ahead, and keep your grip on the steering wheel relaxed. Ensure the vehicle's direction aligns with your line of sight. The farther you look ahead, the sooner you can detect any issues with the vehicle.

What are the penalties for mixing passengers and cargo in a van?

Mixing passengers and cargo in a van results in a deduction of 6 points, a fine ranging from 500 to 2000 yuan, and the vehicle will be detained by traffic police until the illegal status is rectified. Below are relevant details: Definition of mixing passengers and cargo: This generally refers to using a truck to carry passengers or using a passenger vehicle to transport goods. If only the trunk or roof rack of the van is used to carry goods, this does not constitute mixing passengers and cargo. However, if goods are piled up on the rear seats or even the front seats, this is considered mixing passengers and cargo and is illegal. Traffic police can enforce penalties, and offenders will face point deductions and fines if caught.

What are the rules for the reverse parking test in Subject 2?

Detailed introduction to the rules of reverse parking in Subject 2: 1. Failure to enter the parking space: Some students tend to get nervous during the test. The system judges that the main reasons for not entering the parking space are too fast speed, poor clutch control, and inaccurate stopping point, resulting in failure in the first test item of Subject 2. 2. Crossing the line during reverse parking: There are many situations where the line is crossed during the test. For example, turning the steering wheel too late, the car body not being straight, or the speed being too fast. 3. Not following the prescribed route: Due to nervousness during the test, some students directly proceed to the next test item after completing the right reverse parking, ignoring the left reverse parking. Some students directly perform the left reverse parking first and then the right reverse parking, which is also unqualified. 4. Scoring standards for reverse parking: Not following the prescribed route sequence, the car body crossing the line, failure to enter the parking space, the project completion time exceeding 210s, and not having both front wheels touch the ground beyond the control line before reversing will all result in a deduction of 100 points. Stopping for more than 2s during the process will result in a deduction of 5 points per time.

How Often Should You Change the Oil for a Scooter?

For a new scooter, change the oil every 1,000 kilometers initially, and then every 3,000 kilometers thereafter. Below is an introduction to the functions of engine oil: The Lubricating Role of Engine Oil: Between the piston and cylinder, as well as between the main shaft and bearing bush, there is rapid relative sliding. To prevent excessive wear of parts, an oil film needs to be established between the two sliding surfaces. A sufficiently thick oil film separates the surfaces of the relatively sliding parts, thereby reducing wear. The Auxiliary Cooling Role of Engine Oil: Due to its relatively low specific heat value and its location inside the engine, engine oil itself does not have a cooling function. However, as the engine generates heat from fuel combustion during operation, the engine oil can carry the heat back to the oil tank and then dissipate it into the air, assisting the radiator in cooling the engine. The actual cooling is performed by the water outside the engine casing.
