Does Tesla have mandatory scrapping?

Tesla does not have mandatory scrapping. Among private passenger vehicles, 5-seat family cars and 7-seat SUVs, as well as non-commercial small and mini vehicles, have no usage lifespan limit. When the normal mileage reaches 600,000 kilometers, the state will guide the vehicle to be scrapped. The difference between guided scrapping and mandatory scrapping: Guided scrapping is a recommendation for scrapping, but if the vehicle still meets the requirements for continued use, it does not have to be scrapped. Mandatory scrapping means the vehicle must, without exception, be scrapped. There are four criteria for mandatory scrapping: 1. Reaching the prescribed usage period. 2. After repair and adjustment, the vehicle still does not meet the national standards for safety technical requirements for in-use vehicles. 3. After repair and adjustment or the application of control technology, the vehicle's emissions of pollutants or noise still do not meet the national standards for in-use vehicles. 4. Failing to obtain the motor vehicle inspection qualification mark for three consecutive inspection cycles after the inspection validity period expires.

What are the reasons for the poor cooling effect of the Magotan's air conditioning?

The poor cooling effect of the Magotan's air conditioning may be due to the following reasons: 1. Insufficient cooling capacity: First, determine if the air filter is clogged, leading to reduced airflow. This is a common issue. If the air is cool enough but the airflow is insufficient, it may feel like the cooling is inadequate. Replacing the air filter can resolve this. 2. If the air filter is not clogged but the airflow is still low: After checking the air conditioning system and finding no faults, this may be caused by excessive dust in the evaporator. Cleaning the air conditioning system is necessary. Generally, it is recommended to replace the air filter twice a year—once in winter and once in summer. Cleaning the air conditioning system should be done once every one or two years, depending on usage frequency, and should be performed in summer, as winter does not require cleaning for heating. 3. Dirty condenser: This is another reason for poor air conditioning cooling. The condenser is located in front of the radiator and is used to dissipate heat from the refrigerant. It can often become clogged with debris such as lint, leading to poor heat dissipation and reduced cooling performance. Simply rinsing it with a water gun during car washing can easily solve this issue.

How to Deal with Grooves on the Surface of Brake Discs?

Here are the methods to deal with grooves on the surface of brake discs: 1. If the grooves are not deep. You can remove the brake pads and smooth them with coarse sandpaper, then reinstall the polished brake pads. During use, the grooves on the brake discs can be eliminated. 2. If the grooves on the brake discs are deep. You can remove the brake discs and take them to a lathe workshop to grind off the grooves, which is known as resurfacing the brake discs. After installation, they can continue to be used. 3. If the grooves reach the wear limit. The brake discs need to be replaced. The following are the reasons for grooves on brake discs: 1. The brake pads are too hard, or the brake pads are severely worn, exposing metal parts that directly rub against the brake discs, causing grooves. At this time, there should also be a screeching sound. 2. There are sand particles or metal debris between the brake pads and discs, causing grooves after friction. 3. Normal wear of the brake discs. The maximum wear limit for brake discs is 2 millimeters. After reaching the limit, it is necessary to replace the brake discs with new ones.

What Causes the Noise Under the Steering Wheel When Driving on Rough Roads?

Here are the specific reasons for the noise under the steering wheel when driving on rough roads: 1. Check the car's shock absorbers. It is best to go to a 4S shop or repair shop and use a lift to raise the vehicle to inspect whether there are gaps in the shock absorbers or faults in the suspension. If the shock absorber is leaking oil, it may be due to a faulty oil seal gasket, and the shock absorber needs to be replaced. Generally, the service life of a shock absorber is 80,000-100,000 kilometers. When the car reaches 80,000 kilometers, the technician should be asked to check the condition of the shock absorbers during regular maintenance, and repair any faults promptly. 2. Excessive clearance in the steering tie rod ball joint may also cause noise when turning. In severe cases, it may lead to steering wheel shaking or uneven tire wear. The ball joint should be replaced at a 4S shop or repair shop as soon as possible. 3. Excessive clearance or looseness in the lower control arm. The lower control arm is an important component that maintains the elasticity of the car body and is part of the car's suspension. It connects the axle and the frame, helping to absorb the impact of rough roads on the car. Once the lower control arm fails, it should be replaced promptly at a 4S shop or repair shop.
