BMW 320 may produce a buzzing sound when driving, which could be caused by bearing ablation in a certain part. Relevant information about the BMW 3 Series is as follows: 1. Exterior: The original sporty style of the 3 Series has been further retained, featuring a polygonal double-kidney grille and new angel-eye headlights. A groove has been added below the headlights in the middle position, with the bumper lines extending into the groove to connect with the headlights. From the side view, the new car remains very sleek, with the rear-wheel-drive setup resulting in a long hood and short rear end, complemented by a continuous waistline and the new Hofmeister kink. The rear of the new car also follows the family design, with L-shaped elongated taillights, a flat rear end, and dual single exhaust pipes. The new BMW 320/330 models feature a dual-exhaust layout, and the 330 version also includes a small carbon fiber spoiler on the trunk lid. 2. Interior: The overall interior design style of the new BMW 320/330 models is very similar to the current BMW 5 Series and BMW 7 Series. It is equipped with numerous high-tech features: a multifunctional leather steering wheel, a 12.3-inch full LCD instrument panel, a parking assistance system, electric adjustment for the front seats, a driver's seat with memory function, an intelligent connected driving cockpit (including BMW navigation system, BMW Intelligent Personal Assistant, remote software upgrade, etc.), a 10.25-inch central control touchscreen, advanced three-zone automatic air conditioning, independent rear air conditioning, HUD head-up display, wireless phone charging, and various other technological functions. 3. Powertrain: The 320i/320Li and 330i/330Li all use the B48 series 2.0T turbocharged engine, but with different power outputs. The 320i has a maximum power of 115KW, delivering 156 horsepower, while the 330i has a maximum power of 190KW, delivering 258 horsepower. Both are paired with an 8AT transmission.

Does a 2013 car still need inspection in 2021?

A vehicle registered in January 2013 that underwent annual inspection in 2020 will still require inspection before the validity period expires in 2021. The new inspection regulations, effective from November 20, 2020, allow vehicles inspected within ten years to receive a 2-year valid motor vehicle inspection certificate. Relevant information is as follows: New Inspection Policy: The policy expands the scope of motor vehicle exemption from inspection. In addition to the existing exemption for non-operational mini and small passenger vehicles with 6 seats or fewer within 6 years, it now includes non-operational mini and small passenger vehicles with 7 to 9 seats (excluding vans) within 6 years. For non-operational mini and small passenger vehicles (excluding vans) older than 6 years but less than 10 years, the inspection frequency is adjusted from annually to once every two years. Additional Information: Vehicle owners can apply for an inspection certificate up to three months before the expiration of the current inspection period at the local vehicle management office. Before applying, all traffic violations and accidents related to the vehicle must be resolved.

What Causes the Metal Friction Sound from Brake Pads?

Metal friction sounds from car brake pads can be caused by excessively hard brake pads, excessive wear of the brake pads, excessive wear of the brake disc or brake drum, rust on the brake caliper, slow return of the brake master cylinder, among other reasons. Below are the replacement standards for brake pads: Mileage: Under normal driving conditions, the front brake pads should be replaced approximately every 30,000 to 50,000 kilometers, and the rear brake pads every 60,000 to 100,000 kilometers. Once severe wear is detected, they should be replaced promptly. Wear Level: Generally, new brake pads are about 1.5 centimeters thick. If they wear down to one-third of their original thickness, meaning less than 5 millimeters, it is recommended to replace them immediately; If a metal friction sound is heard during braking, this may indicate that the brake pads have worn down to their minimum thickness, causing the limit indicators on both sides of the pads to contact and rub against the brake disc, producing abnormal noises—prompt replacement is necessary; If the brake pedal feels lighter than usual, or if braking feels laborious and ineffective, it indicates severe wear and insufficient thickness of the brake pads, requiring immediate replacement.

What is the difference between buying a car from an auto trade company and a 4S store?

Here are the specific differences between buying a car from an auto trade company and a 4S store: Brand authorization: A 4S store is directly authorized by the car manufacturer, meaning it helps the manufacturer sell cars. In terms of car quality and subsequent feedback on vehicle issues, a 4S store is more reliable. An auto trade company is an ordinary business that obtains cars through 4S stores or other channels, meaning it has no direct relationship with the manufacturer. Car maintenance and servicing: A 4S store integrates vehicle sales, repairs, after-sales service, and parts sales, meaning any car issues can be resolved at the 4S store. An auto trade company mainly sells vehicles and is naturally less professional in maintenance and servicing compared to a 4S store, so it lacks sufficient after-sales support. Car pricing: The operating costs of a 4S store are higher, so buying a car from a 4S store tends to be more expensive because it only sells models of a single brand. Buying a car from an auto trade company is usually cheaper due to diversified sourcing channels and the sale of multiple car brands, resulting in lower operating costs.

Where is the car's air filter located?

The air filter element of the Verano is located in the engine compartment, inside the air filter housing on the right side of the engine. According to the maintenance manual, the air filter should generally be replaced every 10,000 to 20,000 kilometers or every other maintenance interval. However, it is recommended to clean the air filter every 5,000 kilometers to reduce the buildup of sludge in the throttle. The function of the air filter: to filter out particulate impurities in the air, ensuring that clean air enters the cylinders in sufficient quantities, preventing airborne dust from being sucked into the engine and accelerating the wear of the piston group and cylinders. Air filter: It is a type of filter, also known as an air filter cartridge, air cleaner, or air element. It is mainly used in engineering vehicles, automobiles, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms as an air filtration device. During operation, the engine sucks in a large amount of air. If the air is not filtered, the suspended dust in the air will be drawn into the cylinders, accelerating the wear of the piston group and cylinders. Larger particles entering between the piston and cylinder can cause severe cylinder scoring, which is particularly serious in dry and sandy working environments. The air cleaner is installed in front of the carburetor or intake pipe to filter out dust and sand particles from the air, ensuring that sufficient and clean air enters the cylinders. Dirty air filter: Using a dirty air filter while driving can cause insufficient air intake into the engine, leading to incomplete fuel combustion, resulting in unstable engine operation, reduced power, and increased fuel consumption. Therefore, it is essential to keep the air filter clean. The car air filter is a device that removes particulate impurities from the air, consisting of one or several components that clean the air. Its main function is to filter out harmful impurities from the air before it enters the cylinders, reducing early wear of the cylinders, pistons, piston rings, valves, and valve seats. Therefore, before air enters the cylinders, it must pass through the fine filtration of the air filter. A dirty air filter can cause poor engine performance, excessive fuel consumption, and engine damage. When inspecting the air filter, if it is found to have minimal dust and light clogging, it can be cleaned by blowing compressed air from the inside out and reused. A heavily dirty air filter should be replaced promptly.
