What are the three driving modes of the BMW 3 Series?

The three driving modes of the BMW 3 Series are ECO PRO mode, Comfort mode, and Sport mode. Below is a detailed introduction to the three modes of the BMW 3 Series: 1. ECO PRO mode: By adjusting the shifting logic and limiting fuel injection, it achieves fuel-saving effects. The power output is relatively smooth, and to a certain extent, it restricts rapid changes in vehicle speed. 2. Comfort mode: The suspension performs softer and more linearly, the steering response is improved, and the body stability is further enhanced. When passing over speed bumps or applying the brakes and accelerator, it offers better smoothness and comfort, with more prominent cushioning capabilities. The power delivery is gentle, avoiding any sense of jerkiness. 3. Sport mode: The power response is very aggressive. The transmission shifts gears only when the engine reaches higher RPMs, ensuring the vehicle has excellent dynamic performance. However, the strong power inevitably leads to increased fuel consumption and wear on the transmission and engine.

What are the causes of engine shaking at idle?

The causes of engine shaking at idle are: 1. Damaged spark plugs, where the wear of the spark plug electrode gap leads to insufficient spark ignition, resulting in incomplete combustion of the air-fuel mixture; 2. Poor quality gasoline, which affects the atomization effect of the fuel injectors, causing incomplete combustion of the mixture in the cylinder; 3. Dirty throttle body or excessive carbon buildup on the fuel injectors; 4. Abnormal fuel pump pressure or incorrect readings and poor performance of the intake pressure sensor. The function of the engine is to convert thermal energy into mechanical energy by expanding gases after combustion in a sealed cylinder, pushing the piston to do work and providing power to the vehicle. The maintenance methods for the engine include: 1. Cleaning the air filter; 2. Removing sludge from the throttle body; 3. Cleaning carbon deposits from the fuel injectors.

What materials are used to make brake pads?

Brake pads are made from the following materials: 1. Resin-based brake materials; 2. Powder metallurgy brake materials; 3. Carbon-carbon composite brake materials; 4. Ceramic-based brake materials. The function of brakes is to reduce speed or bring the vehicle to a stop. Their working principle involves converting the kinetic energy of the moving vehicle into heat energy through friction between the brake pads and brake drum, as well as between the tires and the ground, thereby slowing down or stopping the car. Causes of brake failure include: 1. Impurities in the master cylinder or poor sealing; 2. Failure of the vacuum booster pump; 3. Contaminated brake fluid; 4. Leakage in the master cylinder or wheel cylinder; 5. Leakage in the air reservoir or pipeline connections; 6. Severe overloading; 7. Carbonization of the brake drum; 8. Insufficient brake fluid in the master cylinder; 9. Wear of the master cylinder piston.

What is the Difference Between Car Glazing and Waxing?

Car waxing and glazing differ in nature, methods, and effects. The specific differences are as follows: Different in Nature: Car glazing involves multiple processes to form a protective layer on the paint surface, similar to the coating on ceramic products. Waxing creates a thin film that protects the car's exterior paint. Different in Methods: Glazing uses a soft wool or sponge with a high-speed vibrating polisher to forcefully penetrate glaze molecules into the car's surface and paint gaps, utilizing the glaze's unique permeability and adhesion. Waxing can be done manually or mechanically, ensuring even application on the paint surface, followed by wiping and polishing. Different in Effects: Car glazing enhances glossiness and hardness. Waxing provides waterproofing, protection against acid rain, adds shine, reduces water droplet adhesion on the car body, and prevents static electricity and dust.

What are the hidden features of the Lavida Plus that can be activated?

The hidden features of the Lavida Plus need to be unlocked at an auto repair shop using a computer. These features include one-key control for raising and lowering all four windows, automatic locking when the speed exceeds 15 km/h, horn sounds when locking and unlocking the car, a car-finding horn, unlocking the driver's door with one press of the remote key and unlocking all doors with two presses, and a taillight reminder when opening the side door. Below are some related details: 1. Most car models actually come preset with many features before leaving the factory, but some of these features are ruthlessly locked when the car is sold. Some are due to the manufacturer's product positioning considerations, as few people buy top-end models, while others are because the car's built-in hardware cannot support them, and too many features may cause lag. 2. Unlocking hidden features is essentially ECU tuning, also known as ECU upgrading. It involves rewriting the program and optimizing parameter settings to increase horsepower, enhance torque, or reduce fuel consumption. It can also unlock many 'hidden programs.'

What Does BMW Basic Maintenance Include?

BMW's basic maintenance items mainly include the replacement of engine oil and oil filter, air filter, fuel filter, and pollen filter, the maintenance/replacement of spark plugs, transmission oil, and other related system inspection and maintenance items. Below are the relevant details: 1. Engine oil and oil filter: Primarily for the maintenance of the lubrication system. The main function of the lubrication system is to effectively lubricate various components of the car engine to prevent excessive wear. The oil filter's function is to remove various impurities from the engine oil to ensure the normal operation of the lubrication system. The oil filter should be replaced along with the engine oil during an oil change. Under normal circumstances, the car should be serviced every 5,000 km. 2. Air filter: The air filter's role is to filter the air before it enters the cylinder, removing impurities, dust, sand, and other foreign particles. The cleaning and maintenance of the air filter depend on the usage environment. The fuel filter is generally replaced after driving 20,000-25,000 km. 3. Spark plugs: Spark plugs are consumable items and should be replaced every 20,000 km. In addition, components such as brake fluid, transmission oil, battery, throttle, fuel injector, and brake pads are all inspection items during routine maintenance, with maintenance performed as needed based on usage conditions.
