Can You Buy a Showroom Car from a 4S Store?

You can buy a showroom car from a 4S store, and there might be a slight discount. Here's some information about showroom cars: 1. Advantages of showroom cars: The odor has mostly dissipated due to frequent opening and closing of doors and people getting in and out. Unless it's a newly displayed car, the smell is usually gone. 2. Categories of showroom cars: Generally, there are two types: (1) One is a brand-new car that's cleaned and displayed in the showroom for customers to view and choose. This type is essentially a new car, just placed in the showroom and maintained daily by sales consultants. (2) Showroom cars purchased by the 4S store with insurance and temporary license plates for touring exhibitions. These cars have to be driven on the road for exhibitions, so they can't be considered truly new.

How to correctly turn on the air conditioning in the Tiguan?

Turn on the AC button of the Volkswagen Tiguan to activate the air conditioning cold air. The reasons why the car air conditioning is not cold are as follows: 1. Refrigerant leakage: Insufficient pressure in the system leads to poor air conditioning cooling effect. 2. Air duct blockage: The air conditioning has not been cleaned for a long time, resulting in a lot of dust on the air conditioning pipelines. At this time, the pipelines need to be cleaned. 3. Poor cooling effect of the condenser: It may be due to equipment aging, or there may be a lot of dust and foreign objects on the surface of the condenser, which affects the exchange efficiency of the air conditioning. 4. Improper use of the air conditioning: If you use the external circulation while turning on the air conditioning, it will definitely transfer the hot air outside the car into the car, and the air conditioning cooling effect will definitely become worse at this time.

What to Do When the Driving License Points Have Not Been Reset by the Due Date?

Reasons and solutions for driving license points not being reset by the due date: 1. Outstanding fines - unpaid fines will carry over the demerit points to the next cycle, so fines should be paid promptly; 2. Accumulated points exceeding 12 - points will not reset automatically after reaching 12, requiring completion of a training course and passing an exam to clear them; 3. If neither applies, it might be due to delayed online data updates, and verification should be done with the traffic police department. Additional information: Consequences of not handling traffic violations promptly: 1. Failure to settle violations before vehicle inspection will result in inspection failure. 2. Violations must be processed before the end of the demerit point cycle, with those exceeding 12 points requiring training and passing an exam to continue driving. 3. Overdue violations exceeding 12 points will lead to license revocation, while those under 12 will carry over to the next cycle. 4. Vehicle transfer requires all violations to be settled, otherwise the new owner will be responsible for them.

What is the maximum wading depth of the Beijing BJ40?

According to official information, the maximum wading depth of the Beijing BJ40 is 80 cm. Common tire specifications include 265/65R17, 245/70R17, and 285/70R17. The vehicle height is 1871 mm, and it is a four-door, five-seat SUV. The maximum wading depth refers to the deepest water level a car can safely pass through. Generally, the maximum wading depth for sedans does not exceed 30 cm, while SUVs can handle slightly deeper water, though it is still advisable not to exceed 50 cm. Among common models, the GAC Trumpchi GS8 has a maximum wading depth of 30 cm, the Audi A4 has 32 cm, the Volkswagen Sagitar has 30 cm, the Land Rover Range Rover has 90 cm, the Jeep Compass has 48 cm, and the Highlander has 45 cm. SUVs clearly exceed many sedans in wading depth. Generally, depending on the depth of water and the vehicle's specifications, drivers should take different measures as follows: If the wading depth reaches the height of the exhaust pipe, it is still safe. Even if water enters the exhaust pipe, the pressure inside is sufficient to expel the water. As long as the engine is not turned off in the water, water will not flow back into the vehicle. If the wading depth reaches the height of the door frame, it becomes more dangerous. The vehicle's circuits, electronic components, and sensors are mostly located at the bottom, which could lead to short circuits, damaging critical electrical components and preventing the car from starting properly. If the wading depth reaches the height of the air intake pipe, it is extremely dangerous. Driving directly into such conditions may cause the engine to stall immediately, resulting in permanent damage or rendering the engine unusable.

What to Do If Water-Contaminated Gasoline Is Added?

After adding water-contaminated gasoline, you can first let it settle to separate the oil and water, then remove the water. However, this method is difficult to completely eliminate the water in the fuel tank and can only remove most of the moisture. It is necessary to remove the car's spark plugs and expose them to the sun for a period of time until it is confirmed that there is no moisture left in the spark plugs. Water-contaminated fuel needs to be treated; otherwise, it can cause frequent stalling and damage the engine. The fuel in the tank is injected into the engine through the fuel injector. The engine continues to work when it receives fuel but stops when it receives water, leading to stalling. If a car encounters heavy rain or water ingress, certain special circumstances may cause water to enter the fuel tank. Improper handling can easily damage the engine, cause frequent stalling, and leave lasting issues. If there is only a small amount of water in the gasoline and the tank is not full, you can continue to add uncontaminated gasoline to reduce the water content. You can also add fuel additives such as fuel tank water removers or fuel system cleaners to help the engine burn more efficiently. If a significant amount of water has entered, you can drain all the fuel from the tank and refill it with uncontaminated fuel. If the car experiences engine shaking or poor acceleration, it is necessary to go to a 4S shop to clean the filter, fuel lines, and injectors. Otherwise, severe cases may result in the car failing to start. Gasoline has strong hydrophilic properties and can absorb moisture from the air, so low water content is not a problem.

Is It Normal for Brake Discs to Rust?

Brake disc rusting is a normal phenomenon. Solutions include: 1. Minor rust: It can be polished off through normal braking. Friction between the brake pads and the brake disc will occur, and after several brakes, the rust can be removed, restoring normal use; 2. Severe rust: The brake pads can be removed and polished, but this will shorten the service life of the brake disc. It is best to replace the brake disc with a new one. Rust on the brake disc will make the surface uneven, causing directional shaking and abnormal noises during braking. The brake disc is an important component of the braking system, divided into solid brake discs and ventilated discs.
