Is Extended Warranty Necessary for BMW Vehicles?

Extended warranty for BMW vehicles is not necessary because BMW's original factory warranty already provides 3 years or 100,000 kilometers of coverage for the entire vehicle. Core components such as the engine, transmission, and chassis are generally durable and unlikely to fail, making the purchase of an extended warranty unnecessary. BMW's vehicle lineup includes the 1, 2, 3, 4, 5, 6, 7, 8, i, M, X, and Z series. The 1 Series is a compact car, the 2 Series is a small coupe, the 3 Series is a midsize car, the 4 Series is a midsize coupe (including convertibles), the 5 Series is a full-size car, the 6 Series is a full-size coupe (including convertibles), the 7 Series is a luxury D-segment sedan, the i Series represents BMW's electric and hybrid vehicles, the M Series is BMW's high-performance and sports car lineup, the X Series is BMW's dedicated SUV (Sports Utility Vehicle) lineup, and the Z Series is BMW's entry-level sports car. The production version of the BMW 4 Series is largely derived from the 4 Series Coupe concept, replacing the former 3 Series Coupe.

What is the appropriate tire pressure in hot weather?

Tire pressure in hot weather is appropriate between 2.3 to 2.5 bar. Tire pressure refers to the air pressure inside the tire. The hazards of excessive tire pressure are: 1. Increases the rigidity of the tire, reduces deformation and contact area; 2. Causes accelerated wear on the central part of the tire tread, shortening the tire's service life; 3. Makes the tire harder, leading to steering wheel vibration, deviation, and reduced ride comfort. Symptoms of low tire pressure include: 1. Steering wheel becomes heavy; 2. Car becomes unbalanced; 3. Reduced car speed; 4. Noise during driving. The functions of car tires are: 1. Work together with the car suspension to mitigate shocks encountered while driving; 2. Ensure good ride comfort and smooth driving; 3. Ensure good adhesion between the wheels and the road surface; 4. Improve the car's traction, braking, and off-road capability; 5. Bear the weight of the car.

Is It Necessary to Wash the Engine Compartment When Cleaning the Car?

It is necessary to clean the engine compartment of a car, but using a water gun to rinse it is not recommended. The reasons and the correct cleaning methods are as follows: Reasons not to use a water gun for rinsing: In addition to the engine itself, the engine compartment contains many electronic wiring and various sensors. After prolonged use and certain rubber aging, the sealing may not be optimal. Rinsing with water flow can cause electrical short circuits, and using a high-pressure water gun to clean the engine does not make it very clean. Correct method for cleaning the engine: Purchase a specialized foam spray for cleaning the engine compartment. Spray it on the dirty areas when the engine is cold to soften stubborn dirt, then wipe with a towel. If it still doesn't seem clean enough, you can use a damp towel for wiping, but be sure to cover the wire ends and sockets. Afterward, use a dry towel or highly absorbent newspaper to wipe the area.

Can You Paint a Car on Rainy Days?

No, rainy days can have certain effects on vehicle painting. Here is some information about vehicle painting: 1. Reason: Rainwater generally contains acidity, and acid rain can significantly damage car paint, easily causing oxidation of the paint surface and loss of gloss. 2. Consequences: The humidity after rain can affect the drying speed of freshly painted surfaces, but the moisture in the air reduces dust levels, which is beneficial for painting. 3. Precautions: (1) If the car has just been painted, avoid exposing the newly painted areas to water and dust; (2) It's best not to drive the car out on rainy days, as the fresh paint is still delicate and can leave marks when exposed to rain, which may be difficult to remove even with polishing. It's advisable to park the car in a garage at night; (3) Don't worry about sunlight, as it only speeds up the drying process of the paint, with no negative effects; (4) Avoid exposing the newly painted areas to chemicals and oil stains.
