What causes the brake noise in Volkswagen Polo?

Here are the reasons for brake noise in Volkswagen Polo: 1. Rust on brake discs or pads: After prolonged parking, especially in humid weather or after rain, rust or dirt may form on the brake discs or pads. This issue can usually be resolved by driving for a while or by applying butter or specialized lubricant at the connection between the brake pads and calipers. 2. New brake pads: Similar noises may occur when braking in a new car or after replacing brake pads. New brake pads and discs require a break-in period, during which such noises are normal. However, if the noise persists after extended use, it indicates a problem. 3. Excessive wear on brake discs or pads: Both components are high-wear items that experience friction during every brake application. Over time, they naturally wear out, leading to noise when excessively worn. Regular inspection and replacement are necessary. Typically, brake pads should be replaced every 60,000-80,000 kilometers, while brake discs last 100,000-120,000 kilometers.

I've been repairing cars for several years and found that brake noise in Volkswagen Polo is quite common. There are several main reasons: the brake pads are worn too thin, or there are grooves or dirt on the brake discs, which can cause metal friction and produce a screeching sound; another reason is that the brake pad material is relatively hard, especially the original parts, which are more prone to noise in winter or humid weather; additionally, the calipers in the brake system may lack lubrication, causing parts to stick. I recommend first checking the thickness of the brake pads—generally, if they are below 3 millimeters, they should be replaced. If the noise persists for several days, take it to a professional shop immediately. Safety is no small matter; brake noise may indicate reduced braking performance, and if a problem occurs at high speed, it could be dangerous. Regular cleaning of the brake components during maintenance can help prevent such issues. In short, don't wait for a small problem to become a big one—timely action is the safest approach.

Why was the NV200 discontinued?

The reason for the discontinuation of the NV200: Due to extremely low market sales, with only 25 units sold in January 2020 and a total of 4,117 units sold throughout 2019, the manufacturer had to make the decision to discontinue the model from a product lifecycle perspective. 1. Body dimensions: The NV200 is an MPV model with a body length of 4400mm, width of 1695mm, height of 1847mm, and a wheelbase of 2725mm. 2. Exterior: The front features a multi-horizontal chrome strip design, with polygonal headlights on both sides. The side profile includes specially designed waistlines and sliding doors. 3. Interior: The interior features a large display screen paired with circular air vents, offering high practicality. However, the vehicle's configuration is relatively simple, with only the top trim equipped with two airbags and no ESP across the lineup. Compared to models in the same price range, the configuration appears overly basic. 4. Powertrain: The NV200 is equipped with a 1.6L engine, delivering a maximum power of 124 horsepower and a maximum torque of 153 Nm, paired with either a 5-speed manual or CVT transmission.

What are the differences between the vv7gt and vv7?

The main differences between the vv7gt and vv7 are concentrated in the rear section of the vehicle. Below are the specific distinctions between the two: 1. The front-end design of both models is nearly identical, with the styling changes primarily focused on the rear section of the doors. The vv7gt features a more refined rear end, adopting a fastback-style design that gives it a sportier visual appeal and a higher visual center of gravity. In terms of exterior design, the vv7gt shares the same front-end styling as the vv7, with the front bumper featuring the latest design, more three-dimensional lines, and a honeycomb grille design complemented by chrome accents. The lower air intake adopts a trapezoidal design, with strip-style front fog lights on both sides. Both models are equipped with ADB adaptive high beams and high-beam polar auxiliary lighting functions. 2. In terms of the side profile, the vv7gt and vv7 have similar waistline designs, both appearing very sleek, with blackened B and C pillars and five-spoke aluminum alloy wheels. The primary difference lies in the rear design—the vv7gt adopts a fastback-style design, resulting in a more sloped rear end.

What are the differences between the Patrol and the Terra?

The biggest differences lie in off-road performance, power, and torque, where the Terra is not as robust as the Patrol. Below are the specific differences between the two: 1. As a rugged SUV in the 200,000 price range, the Terra performs quite well, but compared to the Patrol, the Terra still falls short. Although their names are very similar, in terms of price, power, and performance, the Patrol is a step above the Terra. Additionally, the Patrol is a vehicle under Nissan, while the Terra is under Zhengzhou Nissan, primarily based on the Navara model. Therefore, the Terra is relatively more entry-level compared to the Patrol, and the two are completely different in their origins. 2. The front-end design of the Nissan Terra shares a similar design language with the Navara under the same brand, adopting the family-style "V-motion" design. The bold inverted V-shaped chrome strip design exudes a strong presence, and the size of the grille is very exaggerated. As an off-road SUV, the side design of this vehicle particularly highlights its off-road attributes. The approach angle is 32 degrees, the departure angle is 27 degrees, and the official minimum ground clearance is 225mm. These parameters demonstrate the vehicle's pronounced off-road characteristics.

Why can't the sunroof of the Jetour X70 close?

Jetour X70 sunroof may not close due to the presence of foreign objects inside the vehicle. Meaning of the sunroof: The left and right sides of the sunroof are two sliding rails that ensure the sunroof slides back and forth. At the front corners of the sliding rails on both sides are the sunroof's drainage holes. Common issues with the sunroof: Blocked or broken drainage pipes can result in water seeping out from the sunroof gap and dripping onto the interior. If broken, it can also cause water leakage in the car's A-pillar and C-pillar. Another issue is the aging of the sunroof's sealing rubber strip, leading to water leakage. Faults related to poor contact: If all power windows basically cannot work, the causes of such faults may include the grounding wire of the combination switch falling off, the main power wire falling off, poor contact of the relay, damage, or poor contact of the lock switch or not being closed. The repair method is to inspect and repair the circuit. If the power window is stuck, the causes may include deformation or damage of the window channel or loose screws of the window regulator.

What are the latest regulations for vehicle inspection?

The latest regulations for vehicle inspection are as follows: 1. Expanded exemption scope for private cars: On the basis of exempting non-operational mini and micro passenger vehicles with 6 seats or below from inspection within 6 years, non-operational small passenger vehicles with 7 to 9 seats (excluding minivans) within 6 years are now included in the exemption scope. Applicable vehicle types include non-operational small and micro passenger cars and non-operational large cars, but minivans are not included in the exemption. 2. Penalties for illegal modifications: Vehicles involved in traffic accidents causing casualties or illegal modifications will be penalized according to law. For vehicles that have not completed registration procedures for more than 4 years since the date of manufacture, they will still undergo annual inspection within 6 years as per the original regulations. Minivans, vehicles penalized for illegal modifications, and vehicles involved in traffic accidents causing casualties are not eligible for the exemption policy. 3. Optimized exemption cycle: For non-operational mini and micro passenger vehicles (excluding minivans) over 6 years but under 10 years, the inspection frequency is adjusted from once a year to once every two years.
