Is it normal to hear a ticking sound from the chassis after parking?

It is normal to hear a ticking sound from the chassis after parking. The reasons are as follows: The ticking sound from the chassis after parking is mostly the cooling sound of the catalytic converter, which is a normal phenomenon. Of course, there are other reasons, but most of the sounds produced after the car is turned off are caused by thermal expansion and contraction, so car owners don't need to worry. Source of the sound: The ticking sound from the chassis may be the cooling sound of the catalytic converter. The working temperature of the catalytic converter is very high, so when the car is turned off, the temperature drop requires a process. Moreover, it is mostly made of metal parts, so according to the principle of thermal expansion and contraction, a ticking sound will occur. The cooling sound of the exhaust pipe. The ticking sound from the exhaust pipe mostly comes from the front end of the exhaust pipe and the flexible connection. When the car is running, the temperature is high, and during the temperature drop process, the ticking sound is caused by the thermal expansion and contraction of the metal parts. Turbo cooling sound. Normally, the temperature of the exhaust gas produced by the car is around 700 degrees. After the car is turned off, the sound produced by the metal parts due to thermal expansion and contraction becomes more obvious. Abnormal noise caused by uneven cooling of the engine. After the car has been running for a while, the engine temperature will be very high. However, after the engine is turned off, the temperature drop rates of various parts are inconsistent, so the gaps between various parts of the engine will rub against each other due to thermal expansion and contraction, producing abnormal noise.

Is It Safe If There's No Notification After Running a Red Light for 7 Days?

If there's no notification after running a red light for 7 days, it doesn't necessarily mean it's safe. Typically, violation notification messages from traffic cameras are sent within 3 to 7 days, with the latest being around 13 days. However, some cities now offer "instant electronic police capture alerts," where you may receive an SMS notification within 5-10 minutes of being captured. But this notification does not confirm a violation; it merely serves as a capture alert. The final determination of whether it's a violation takes 3-7 days. If it is indeed a violation, you will receive another SMS notification. For traffic violations captured by surveillance cameras, vehicle owners usually do not receive violation notifications immediately. There is a delay, and the duration varies. After capturing a violation, electronic cameras need to transmit the relevant violation information to the traffic police management center through a dedicated channel. The information is then compiled and reviewed by relevant traffic police personnel. If confirmed as a violation, the system automatically retrieves the vehicle owner's phone number based on the license plate information and sends the violation details via SMS. After receiving the violation SMS, vehicle owners must go to the local traffic police department where the violation occurred to handle the matter within one month before the vehicle's annual inspection. Generally, if you suspect a violation, you can use 15 days as a benchmark. If no violation SMS is received within 15 days, it is likely that no violation was recorded. Traffic Violation Query Methods: Traffic violation queries refer to checking motor vehicle violations of traffic regulations through online platforms or query terminals. Methods include website queries, phone queries, SMS queries, and mobile app queries. Website Query: Search for "vehicle violation query" and input vehicle information to check. Phone Query: Dial local 114 (area code + 114) or 12580 to confirm traffic violations. Violations can only be processed at the location where they occurred or where the vehicle's license plate was issued. For on-the-spot violations, such as those directly caught by traffic police, processing must be done at the violation location. SMS Query: Open your phone's SMS interface, input the violation license plate number and color, and send it to 1062650001. Mobile App Query: Open the "Traffic Management 12123" app, select "violation query," and clear any unresolved violations.

Why Do White Cars Develop Black Marks After Waxing That Can't Be Wiped Off?

White cars develop black marks after waxing that can't be wiped off due to paint oxidation. Explanation of the cause: Paint oxidation is closely related to waxing. The phenomenon where waxing causes the paint to appear dull is due to this. The main component of car paint is resin, which naturally oxidizes. The basic components of car wax are also resin or petroleum-based products, which are prone to oxidation as well. In fact, they can even resonate with the paint surface, accelerating oxidation. Solution: First, polish the surface to remove the oxidized layer and scratches, then perform regular maintenance. Maintenance methods: Try to wax less frequently. If waxing is necessary, be sure to choose a high-quality wax, or else the paint may become dull again in a short time. Many car waxes contain abrasive particles, which can also damage the paint surface. Glazing is not recommended, as its components are similar to wax, differing only in application method. Over time, it can also dull the paint, though it offers slightly better hardness and durability than wax. If possible, consider getting a coating, but make sure to choose a reputable service provider and negotiate the price aggressively. For a more economical option, DIY coating is recommended—it has no negative effects and works well. The advantage is cost savings, while the downside is the effort required to apply it yourself. Precautions: Do not wax a new car unnecessarily. Some people wax their new cars immediately after purchase, which is not advisable. New cars already come with a protective wax layer, and premature waxing can remove this original coating, leading to unnecessary waste. Generally, new cars do not need waxing within the first five months. Waxing frequency should be adjusted based on driving and parking conditions. For cars parked in garages and driven mostly on good roads, wax every 3-4 months. For cars parked outdoors exposed to the elements, wax every 2-3 months. However, this is not a strict rule—wax whenever the body feels rough to the touch. Before waxing, wash the car with car shampoo to remove dirt and dust. Avoid using dish soap or soapy water, as they contain sodium chloride, which can damage the paint, wax film, and rubber parts, causing the paint to lose its shine and rubber parts to age. If no car shampoo is available, rinse with clean water and dry the car before waxing. Wax the car in a shaded area to prevent the body from heating up, as high temperatures reduce wax adhesion and affect the quality of waxing.

Do tires that are six years old but rarely driven need to be replaced?

Tires that are six years old but rarely driven should be replaced. Reason explanation: You should replace tires for the sake of replacing them—it's a way to protect your car and take responsibility for your life. Tires have a limited lifespan. In fact, tires wear out and age over time. Even if they show no visible wear, tires should be replaced after four years from the date of manufacture, at least the front tires. The only exception is if you drive at low speeds. If the tires are worn down to the wear indicators and are over four years old, they should definitely be replaced (again, unless driven at low speeds). Additionally, you don’t necessarily have to replace all four tires at once—you can replace them in pairs as needed, which is a cost-saving approach. Like engine oil, there’s no strict standard for when to replace tires. Different grades of tires have varying resistance to heat and aging. Tires exposed to the hot, humid summers of the south will age differently than those in the mild, dry summers of the north. If your car is parked in an air-conditioned garage at home and at work, the tires will degrade differently. Tires left exposed to sunlight for long periods, frequently driven on rough roads, often underinflated, with damaged sidewalls, or patched multiple times should be replaced earlier. Regular inspection and maintenance can help extend tire life, but all tires will eventually wear out. Tire lifespan varies depending on driving habits, local climate, and how well they are maintained. Any worn or damaged tires will eventually need replacement. Tire introduction: Car tires are one of the most important components of a vehicle. They directly contact the road surface and, together with the suspension system, help absorb shocks during driving, ensuring a comfortable ride and smooth handling. They also provide good traction between the wheels and the road, improving the car's acceleration, braking, and off-road capability. Additionally, they bear the weight of the vehicle. The critical role tires play in a car’s performance is increasingly being recognized.

How to Perform Parallel Parking?

How to Perform Parallel Parking Operation: Operation Method: First, the driver should drive forward until the side mirror aligns with the vertical line between the two doors of the adjacent vehicle. When the lateral distance between the two vehicles is approximately 30 centimeters, the driver can turn the steering wheel to the right and begin reversing. When the left side mirror can see the right front headlight of the rear vehicle, the driver should turn the steering wheel to the left while continuing to reverse. Once the vehicle is fully within the parking space, the steering wheel should be returned to the center position. During this process, it is essential to use the vehicle's radar and rearview camera to avoid scraping surrounding vehicles. If executed correctly, this method ensures successful parallel parking. However, as a beginner, regular practice is necessary to build confidence and technical proficiency. If either aspect is lacking, attempting such a high-skill parking maneuver is not advisable. Introduction to Parallel Parking: Parallel parking is a component of the second subject in the driver's license test. It has become increasingly common in urban areas, especially as parking spaces in formal lots grow scarce. Many streets now have designated "parallel parking spaces" marked along their sides. Previously, parallel parking involved four poles placed on the ground to symbolize the corners of the parking space. Success was measured by whether the vehicle entered the space without touching these poles. After the implementation of new traffic regulations, parallel parking no longer uses poles; instead, boundary lines on the ground define the parking space. For learners of the C1 driver's license, the length of the parallel parking space is 1.5 times the vehicle's length plus 1 meter. The vehicle must be driven parallel to the parking space, then reversed into it without any pauses. As long as the vehicle stays within the boundary lines, the maneuver is considered successful.

Why Do Mercedes-Benz Sensors Fail?

Mercedes-Benz sensors may fail due to poor fuel quality, abnormal working voltage of spark plugs and ignition coils, and poor working condition of the three-way catalytic converter. Explanation of Reasons: Pay attention to fuel quality and try to avoid refueling at small gas stations. Check whether the working voltage of spark plugs and ignition coils is normal. Inspect the three-way catalytic converter to ensure it is functioning well and free from blockages. Once a sensor fails, the computer of the electronic fuel injection system will not receive information about the oxygen concentration in the exhaust pipe. If feedback control of the air-fuel ratio is compromised, it will lead to increased engine fuel consumption and exhaust pollution, as well as symptoms such as unstable idling, misfires, and surging. Damaged sensors should be replaced or repaired as soon as possible. Introduction to Sensors: Automotive sensors are input devices for the car's computer system. They convert various operational conditions of the vehicle, such as speed, temperature of various media, and engine operating conditions, into electrical signals for the computer, ensuring the engine operates in the optimal state. Sensors play an extremely important role in automobiles. If a sensor malfunctions, the corresponding device may not work properly or even cease to function. Among the many sensors, the speed sensor is relatively prone to failure. Symptoms include: unstable engine idling; momentary stalling or engine shutdown when starting or decelerating to a stop; reduced engine acceleration performance; discrepancies in the speed displayed on the dashboard; and the engine warning light turning on.
