Replace with a new set of gears. Below are detailed introductions about the types of rearview mirrors: 1. Interior rearview mirror: Allows the driver to confirm the rear view without significantly altering the forward line of sight while driving. 2. Exterior rearview mirror: Typically mounted on the doors of passenger vehicles. 3. Undermirror: Enables the driver to see areas beyond the front and rear wheels beneath the car body through a mirror positioned directly in front of the driver's seat. It also helps the driver spot people or obstacles near the wheels and vehicle sides when reversing or starting forward, preventing injuries, damage to objects or the vehicle, and ensuring convenience and safety for the driver.

Last time, the folding function of my car's rearview mirror broke, specifically the gear inside snapped. I'm the kind of person who enjoys DIY, and seeing the problem was simple, I decided to fix it myself. Taking off the rearview mirror cover wasn't difficult at all—just a small screwdriver did the trick. Inside, I found the gear shattered into pieces. I went online and bought an original replacement part for about twenty or thirty bucks, waiting for the delivery. When installing it, I took my time to avoid breaking any wire connectors, and applied a bit of lubricant to make the new gear move smoothly. After the repair, it folded as flexibly as new, saving me a trip to the repair shop. I usually pay more attention while driving now, avoiding frequent collisions with hard objects to prevent wear and tear. Doing it myself turned out to be simpler than I thought—watching more video tutorials to learn the steps can also help prevent similar issues. Next time something goes wrong, I'll fix it myself again.

Do I Need to Report to My Insurance If I Get Rear-Ended?

If your car is rear-ended and the other party is fully at fault, you do not need to involve your own insurance. The at-fault party should notify their insurance company, which will assess the damage and provide compensation. If the at-fault party does not have insurance, they are responsible for covering all damages. Below are the relevant provisions from the "Road Traffic Safety Law of the People's Republic of China": 1. Article 73: The traffic management department of the public security organ shall promptly prepare a traffic accident certification based on the on-site investigation, inspection, and relevant testing or appraisal conclusions, which serves as evidence for handling the traffic accident. The traffic accident certification shall specify the basic facts, causes, and responsibilities of the parties involved and shall be delivered to the parties. 2. Article 74: In case of disputes over compensation for traffic accident damages, the parties may request mediation from the traffic management department of the public security organ or directly file a civil lawsuit with the People's Court. If the parties fail to reach an agreement through mediation or do not fulfill the mediation agreement after it takes effect, they may file a civil lawsuit with the People's Court.

What is the fuel consumption of the Mazda Axela?

Mazda Axela's fuel consumption ranges from 5.2L to 6.2L. The naturally aspirated engine of the Mazda Axela demonstrates excellent fuel efficiency, largely due to the synergy between the engine and transmission, as well as reasonable driving logic and efficient operation. Here is the extended content: 1. Fuel consumption of different Axela versions: The 1.5L version of the Axela has a combined fuel consumption of 4.6-4.9L/100km; the 2.0L version has a combined fuel consumption of 4.9-5.4L/100km. 2. Combined fuel consumption: The reason for providing a range of combined fuel consumption is that different versions of the model have varying fuel consumption values, such as the flagship version and the premium version having certain differences in fuel consumption. Additionally, the fuel consumption tested by the Ministry of Industry and Information Technology is conducted indoors, which differs significantly from real-world usage scenarios, so it often fails to achieve such "ideal" fuel consumption.

Does Maybach 4S Store Offer Logo Replacement?

Maybach 4S stores do not offer logo replacement. Here are specific details about Maybach: 1. Background: Maybach and Maybach Motorenbau were a German ultra-luxury car brand and manufacturer active in Europe between 1921 and 1940. The founder of the company, Karl Maybach's father, Wilhelm Maybach, served as the Chief Technical Director of Daimler-Motoren-Gesellschaft (the predecessor of today's Daimler Group), indicating a deep connection between the two companies. In 1997, the DaimlerChrysler Group showcased a concept ultra-luxury four-door sedan named Maybach at the Tokyo Motor Show, officially reviving this German car brand after years of absence. 2. Company History: On February 9, 1846, Wilhelm Maybach was born in Heilbronn, Germany, with four siblings. Later, the family moved to Stuttgart. At the age of 10, Wilhelm Maybach lost both parents and became an orphan. Fortunately, when facing life difficulties, a charity organization saw the adoption notice in the Stuttgarter Anzeiger newspaper and agreed to take care of Wilhelm Maybach. During his education at Reutlinger Bruderhaus and Gustav Werner, the school's founder and director recognized Wilhelm Maybach's technical talent and nurtured him well, laying a solid foundation for his future development.

What Causes Idle Vibration in Passat?

Passat idle vibration is mainly caused by the following reasons: 1. Unstable oil pressure: If the fuel pump supply pressure is abnormal, or the intake pressure sensor value is incorrect and malfunctioning, it can cause idle vibration of the vehicle body. It is best to check the oil pressure and replace components if necessary. 2. Aging engine components: Aging engine components, such as worn engine mounts, can cause idle vibration of the vehicle body. Engine mounts are actually the shock absorption system of the engine, responsible for absorbing minor vibrations during engine operation. If the engine mounts are faulty, these vibrations will be transmitted to the steering wheel and the interior of the vehicle. 3. Excessive carbon buildup and dirt: A dirty engine throttle or excessive carbon deposits on the fuel injectors can also cause idle vibration. When there is excessive carbon buildup, the gasoline sprayed by the cold start injector will be largely absorbed by the carbon deposits, resulting in an overly lean mixture during cold starts and difficulty in starting. After the engine starts, the gasoline adsorbed on the carbon deposits will be sucked into the cylinder by the engine's vacuum and burned, making the mixture too rich. This causes the engine's combustible mixture to alternate between being too lean and too rich, leading to idle shaking.

Does shifting from P to R with a clunk sound damage the car?

Shifting from P to R with a clunk sound can be quite damaging to the car. Here is an introduction to related knowledge about gear shifting: 1. Standardized shifting is required: The rattling noise when shifting into reverse gear is caused by improper operation during the shift. If gear grinding occurs frequently, the gear crowns will wear down, resulting in incomplete gear engagement. Moreover, frequent operation like this creates a vicious cycle: the more grinding occurs, the more wear there is, and the more wear there is, the more grinding occurs. Incomplete gear engagement can lead to the phenomenon of gear disengagement with slight vibrations after shifting, at which point a major transmission overhaul is required. 2. Precautions: Switching an automatic transmission to R gear indicates that the transmission gear set has engaged with the reverse gear. If there is no braking force or resistance, the vehicle will definitely move, meaning the power transmission has already been connected. Even if you ignore the alarm or forcibly turn off the engine and park the car while in R gear, it will not provide effective parking function, because compared to the pawl locking function of P gear, the gears in R gear are not locked.
