Why does it make a clunking sound when shifting to D gear?

Introduction to the reasons for the clunking sound when shifting to D gear: 1. Shifting without stopping the car completely: When parking, you should first bring the car to a complete stop before shifting the gear lever from D gear to P gear. If you shift to P gear before the car is fully stopped, the P gear lock hook inside the transmission will hit the gear, producing a clunking sound. This operation can cause the lock hook to wear or even break, and in severe cases, it can lead to transmission failure. 2. Incorrect operation sequence when parking on a slope: For automatic transmission models, the P gear relies on the lock hook to engage the gear to keep the car stationary. When parking on a slope, you should first apply the handbrake and then shift to P gear, allowing the handbrake to bear the vehicle's sliding force. If you shift to P gear first and then apply the handbrake, the sliding force will be entirely borne by the P gear lock hook, causing tension between the lock hook and the gear. This will result in a noise when shifting from P gear to other gears. 3. Malfunction in the gearshift mechanism: Many automatic transmission models with gear levers actually use mechanical structures to shift gears. Over time or due to corrosion, the connecting parts of the gearshift mechanism can become loose or stuck, leading to noise when shifting gears. 4. Wear and tear on transmission gears: The transmission is a precision component, and the gears are the most critical part. The meshing of transmission gears is extremely tight, leaving no room for any gaps. However, because of this tight meshing, wear and tear are inevitable. Over time, significant gaps can develop between the gear teeth, resulting in noise when shifting gears.

BAC of 20mg~40mg/100ml or driving under the influence without entering the city center: 1-2 months driver's license suspension and a fine; 2. BAC of 60mg~80mg/100ml or a second offense within one year: 3 months driver's license suspension and a fine; 3. BAC of 80mg~100mg/100ml or drunk driving without entering the city center: up to 15 days of detention, 3-6 months driver's license suspension, and a fine; 4. BAC exceeding 100mg/100ml or drunk driving in the city center: 15 days of detention, 6 months driver's license suspension, and a fine.

What are the tips for point deduction questions in the driving test?

Here are some tips for point deduction questions in the driving test: 1. Scoring cycle: A scoring cycle lasts 12 months. If the points are fully deducted within a cycle, you must undergo education and retake the test. 2. Point reset: The reset of driving license points is not at the end of the year but depends on the date you obtained the license. 3. Point deduction scenarios: In the subject one test, there are no scenarios of deducting 1 or 2 points; the most frequent deductions are 6 and 12 points. 4. Speeding: Speeding less than 20% results in a 3-point deduction; speeding less than 50% results in a 6-point deduction; and speeding more than 50% results in a 12-point deduction.

What to Do When the BMW Trunk Switch Fails?

You can use the key to open the trunk, remove the interior trim, and measure whether the electric motor has power. If there is power, the issue is with the motor; if there is no power, the issue is with the wiring. More knowledge about the trunk is as follows: 1. Introduction: The car trunk mat, also called the car boot mat, refers to the mat placed at the bottom of the car trunk. The car trunk is a place for storing items, and its role should not be overlooked. 2.

How to Deal with Fogging Inside the Car During Summer Rain?

Fogging inside the car during summer rain can be addressed by applying anti-fog spray, using the air conditioning's cooling and heating functions. Here are the solutions for summer rain-induced car fogging: 1. Preventive methods like applying anti-fog spray: Spray a small amount of anti-fog agent on the car windows (inner surface) and wipe it clean to remove dirt and stains. While polishing the glass, a thin transparent protective film is formed, effectively preventing water vapor from condensing into fog. 2. Anti-fog spray method: Utilize the air conditioning's dehumidification function to reduce air humidity and eliminate fog. 3. Air conditioning warm air method: During summer rain, you can also blow warm air onto the windows to quickly raise the temperature of the front glass, reducing the temperature difference between the inner and outer surfaces. This helps prevent excessive fogging on the windshield promptly. However, it should be noted that the rear and side windows heat up more slowly, requiring more time to completely remove all fog.

Are new cars exempt from inspection for 6 years?

New cars are exempt from inspection for 6 years. The 6-year exemption for new cars means that the vehicle does not need to undergo on-site inspection at a vehicle inspection station for the first 6 years, but the owner still needs to conduct a periodic check every two years. During the first 6 years, in the second and fourth years, the owner only needs to complete some related procedures, while in the sixth year, the owner must take the car to the inspection station for an on-site inspection. Only after passing the inspection can the owner receive the inspection mark. Below is an introduction to the vehicle inspection requirements: 1. Commercial passenger vehicles: Inspected once a year for the first 5 years; after 5 years, inspected once every 6 months; 2. Trucks and large or medium-sized non-commercial passenger vehicles: Inspected once a year for the first 10 years; after 10 years, inspected once every 6 months; 3. Small and mini non-commercial passenger vehicles: Inspected once every 2 years for the first 6 years; after 6 years, inspected once a year; after 15 years, inspected once every 6 months; 4. Motorcycles: Inspected once every 2 years for the first 4 years; after 4 years, inspected once a year; 5. Tractors and other motor vehicles: Inspected once a year. Commercial motor vehicles that pass the safety technical inspection within the specified inspection period do not need to undergo repeated safety technical inspections; 6. Vehicles that exceed the scrapping age cannot be transferred (sold or bought) but can continue to be used: For transactions, the owner can first apply for the vehicle’s scrapping certificate (to deregister the vehicle’s file) at the vehicle management office, and then proceed with the transaction.
