What is the reason for the constant door rattling when driving on bumpy roads in the Buick Excelle?

Why does the Teana not retain its value?

The Teana's poor value retention is primarily due to three main reasons: rapid model price reductions, the general depreciation of Japanese cars, and relatively poor sales performance. Among its peers, the Teana lags behind competitors such as the Passat, Magotan, and Accord. Additionally, the pricing of the Teana is another factor affecting its depreciation rate. Methods to determine whether a car is new are as follows: 1. Check the manufacturing date: The vehicle's manufacturing date should match the date on the certificate of conformity, which is usually difficult to alter. If the manufacturing date exceeds 15 days, it is considered an old car. 2. Inspect the brake discs: Most modern small passenger vehicles use disc brakes (at least for the front brakes), making the brake discs a reliable indicator. Typically, after driving more than 200 kilometers, the brake pads will leave noticeable marks on the brake discs. There is usually a 1-2 mm gap between the brake pads and the outer edge of the brake discs. After a certain distance is traveled, a noticeable "ledge" (very low in new cars) will form on the outer edge of the brake discs.

Why is the rear seat light always on?

If the rear seat light is always on, first check whether the switch has been triggered, and then consider the possibility of a wiring fault. The car light has three modes: 1. ON: Constant-on mode. When this switch is turned on, the ceiling light will stay on continuously and will not turn off even after the car is locked. 2. DOOR: In this mode, the light only turns on when the door is opened. 3. OFF: When this mode is selected, the ceiling light remains off and will not illuminate. Below is an extended introduction about car headlights: 1. Function: Car headlights are used for illumination during nighttime driving. Also known as car front lights or LED daytime running lights, they serve as the "eyes" of the car, not only affecting the owner's external image but also closely related to safe driving at night or in bad weather conditions. 2. Types: (1) By purpose: Car lights can be divided into two categories: illumination and auxiliary. Among them, only the headlights and some fog lights equipped on certain cars serve an illumination purpose, while the rest are auxiliary lights. (2) By category: Currently, there are four types of car headlights: laser headlights, LED car headlights, xenon headlights, and halogen lights.

What is the H-series of the Tiggo 8 headlights?

The Tiggo 8 headlights are H7. The maintenance methods for the headlights are: 1. Check the sealing of the headlights. If there is moisture inside the headlights, it will reduce the lifespan of the bulbs. If the sealing ring between the lens and the reflector is damaged, replace it promptly. 2. Clean the bulbs. Use alcohol-soaked degreasing cotton to wipe off dust and dirt on the bulbs. After cleaning, let them dry and avoid touching the bulbs with hands or cloth. 3. Clean the reflector. Use clean cotton dipped in hot water to clean the reflector, but do not wipe it to avoid damaging the reflector coating. Taking the 2020 Urban Edition Tiggo 8 as an example, its front suspension is a MacPherson independent suspension, and the rear suspension is a multi-link independent suspension. It is equipped with a 1.5L turbocharged engine, with a maximum horsepower of 156 PS, a maximum power of 115 kW, and a maximum torque of 230 Nm. It is paired with a 6-speed manual transmission.

What is the difference between Audi A4 35 and 40?

Audi A4 35 and 40 represent differences in gravitational acceleration ratio. Numbers are used to replace displacement, with larger values indicating better acceleration from 0 to 100 km/h. The main difference between A4 30TFSI and 40TFSI models lies in their completely different engines and transmissions. More details are as follows: 1. Increased power: For the current A4 models, the new versions no longer have 35TFSI, starting from 40TFSI as the minimum. Even with the same 2.0 displacement, the new 40TFSI has greater engine power and torque compared to the old 35TFSI, meaning improved overall power. 2. 35TFSI meaning: This indicates the vehicle's acceleration is approximately 0.35 times the free-fall acceleration (gravitational acceleration g). Free-fall acceleration to 100km/h takes about 2.83 seconds, so this vehicle requires roughly 8.1 seconds to reach 100km/h (35TFSI, 40TFSI, 45TFSI, 50TFSI etc. use 5 as quantization unit, with certain quantization errors).

What kind of lubricating oil is used for the brake caliper guide pins?

Ecco-Grease-EM71-2 special grease for plastic and rubber. Below are the relevant details: 1. Introduction to brake caliper and guide pin lubricant: Ecco-Grease-EM71-2 special grease for plastic and rubber is a lubricating grease made from polyether synthetic oil as the base oil, special lithium soap as the thickener, and refined with various additives such as antioxidants, anti-corrosion agents, and anti-aging agents. This plastic and rubber compatible grease is designed for the assembly lubrication of rubber, plastic, and metal components that are sensitive to most greases, such as ethylene propylene diene monomer rubber, styrene-butadiene rubber, and natural rubber. It features excellent adhesion, wear resistance, and corrosion resistance. 2. Brake caliper: An essential component of the chassis braking system, its main function is to push the brake pads, which then rub against the brake drum to reduce speed and bring the vehicle to a stop. When the brake pedal is pressed, the master cylinder generates thrust to push hydraulic oil to the caliper, and the piston inside the caliper moves under hydraulic pressure to push the brake pads.

Why is the Tiggo 8 Plus more fuel-efficient than the Tiggo 8?

Tiggo 8 Plus is more fuel-efficient than Tiggo 8 for two reasons: First, although the Tiggo 8 PLUS is larger in size than the Tiggo 8, the curb weight of both vehicles is the same at 1.54 tons, which proves that the Tiggo PLUS has done a good job in body lightweighting; Second, on the Tiggo 8 PLUS, the tuning of the 1.6T+7DCT powertrain is more economical and smoother compared to the Tiggo 8. The differences between the Tiggo 8 and Tiggo 8 Plus are: 1. Different engines: The Tiggo 8 engine is a 1.5TL4; The Tiggo 8 Plus engine is 126kW (1.5L turbocharged + electric motor). 2. Different length and height: The Tiggo 8 length and height are 4700mm and 1746mm respectively; The Tiggo 8 Plus length and height are 4722mm and 1745mm respectively. 3. Different transmissions: The Tiggo 8 transmission is a 6-speed manual; The Tiggo 8 Plus transmission is a CVT. 4. Different maximum torque: The Tiggo 8 maximum torque is 230nm; The Tiggo 8 Plus maximum torque is 250nm.
