Trunk drain plugs should be removed. Here are the reasons why trunk drain plugs need to be removed: 1. Prone to rust: Each car door typically has two or more drain holes, usually located at the lower part of the door panel. If not removed, water can accumulate inside the door, leading to rust over time. 2. Prone to short circuits: The door contains many components, including window regulators and audio system wiring. If exposed to water, these components can be damaged. 3. Prone to clogging: Since the drain holes on the doors are positioned low, they can easily get clogged with mud when driving on muddy roads. Therefore, it's important to clean the drain holes on the doors promptly.

Having driven for over twenty years, my experience tells me that the trunk drain plug should definitely be removed. That little plug was originally designed for temporary dust or small animal prevention, not for long-term use. If left in place, water can accumulate under the trunk floor, leading to corrosion of metal parts over time, such as rusting the trunk structure. It may also seep into the spare tire compartment or tool storage area, damaging carpets and other items. Even worse, stagnant water in hot weather can breed mold, causing unpleasant odors inside the car and affecting health. This is especially problematic during rainy seasons or after car washes, as trapped water can lead to more severe consequences. During every maintenance check, I make it a habit to clean the drain holes with a small brush or air gun to remove leaves and debris, ensuring they stay clear—a process that takes less than ten minutes and is simple yet effective. Don’t worry about dust; it’s much easier to handle than water accumulation. Remember to develop the habit of checking before each winter to avoid frozen and cracked pipes.

As a car owner, handling the trunk drain plug is straightforward: remove it. This hole is designed for drainage, and the plug is only for temporary protection. If not removed, rainwater or car wash water can easily accumulate on the floor panel, leading to rust and corrosion. In severe cases, it may damage electrical wiring, resulting in costly and time-consuming repairs. When I check it myself, I simply open the trunk, locate the drain hole, gently pull out the plug, and then use a thin wire to remove any blockages. Cleaning it once a month is sufficient to ensure smooth drainage. If parked in a dusty area, it's fine to leave the plug in for a couple of days, but it should be removed immediately afterward. Save money and hassle—don't overlook this detail, as water accumulation can lead to repairs costing thousands. Developing a regular maintenance habit will make your car more durable.

Many car owners make this mistake in the community chat: using the trunk drain plug as a permanent fixture. In fact, this hole is designed by the car manufacturer specifically for drainage, and the plug is only a temporary dust-proof measure. If you don't remove the plug, water will accumulate at the bottom of the trunk and corrode the car body. My neighbor's car rusted due to water accumulation, and the trunk floor rotted away, requiring repairs for over half a year. It's recommended to remove the plug to ensure smooth drainage. The cleaning method is simple—just use a stick or a vacuum cleaner to clear the hole. Don't be lazy; it's crucial for the long-term health of your vehicle.

What are the consequences of using semi-synthetic oil for a year?

Semi-synthetic oil will deteriorate after one year of use, which can damage the engine. Replacement cycle for semi-synthetic oil: In most Chinese cities, semi-synthetic oil can be replaced every 7,500 kilometers or 9 months. If there is too much dust in the air, the temperature is very low (-20 degrees Celsius), or the car is frequently driven short distances (each trip is less than 8 kilometers), it is recommended to increase the oil change frequency to 5,000 kilometers or every six months. Shelf life of semi-synthetic oil: National regulations clearly state that the shelf life of sealed oil is generally within 5 years, and semi-synthetic oil also falls within this range. However, once opened, semi-synthetic oil deteriorates more quickly and should ideally be used within six months. Of course, how quickly semi-synthetic oil deteriorates also depends on the storage environment—the greater the temperature fluctuations and humidity, the faster the oil will deteriorate.

What Causes the Car Display Screen to Suddenly Go Black?

There are several reasons why a car display screen may go black: DVD Operation Lag: If the DVD operation experiences lag, causing the car display screen to go black and become unresponsive to touch, restart the power supply of the car display screen; Software Incompatibility: Third-party software may be incompatible with the system. Check if any new software has been downloaded recently. A crash could be caused by unstable programs or insufficient memory. In this case, it is necessary to free up some memory and uninstall the relevant software; Screen Damage: Determine whether the screen is damaged, if there is an issue with the wiring, or if the crash is caused by the IC or motherboard. This is the most common scenario. If it is a hardware issue, the only solution is to take the car to a 4S shop for repair or to a repair shop for inspection.

Can a Bulging Tire Run 100 Kilometers?

A bulging tire cannot run 100 kilometers. The impacts and causes of tire bulging are as follows: Impacts of Tire Bulging: A bulging tire not only affects driving but also poses a serious risk of sudden blowout at any time, which is a major accident hazard for vehicle operation. Once a tire bulge is detected, it must be immediately inspected and replaced at a professional tire shop. Causes of Tire Bulging: Excessive tire pressure makes the tire too hard and reduces elasticity, increasing the risk of blowout upon external impact. Insufficient tire pressure increases the contact area between the tire and the ground, making it prone to breakage of the tire cords when hitting hard objects. Therefore, tire bulging is not due to poor tire quality but is caused by uneven road surfaces and unstable tire pressure.

Does Audi Offer Free Roadside Assistance?

Audi's rescue service vehicles provide a 24-hour integrated rescue solution. With powerful professional equipment and a dedicated team, they offer various forms of assistance including towing, oil delivery, fuel delivery, and on-site emergency repairs, ensuring you receive swift and professional service when you need it most. Free Jump-Start Service: Free jump-starts are quite common. For instance, if a driver forgets to turn off the headlights overnight, the car battery may drain, leaving the vehicle unable to start the next day. In such cases, drivers can seek help from a 4S shop or repair shop, but they usually charge a fee. However, if the driver contacts their car insurance company, they typically offer free jump-start services, though there may be usage limits, so drivers should still try to conserve battery power. Free Fuel Delivery Service: Many absent-minded drivers often forget to check their fuel levels while driving. Running on low fuel can cause the car to stall unexpectedly, especially if there are no nearby gas stations, leading to frustration. In such situations, drivers don't need to panic. Simply calling their car insurance company will usually result in a fuel delivery within an hour, with the driver only needing to pay for the fuel itself.

What does 'Slow down, drive carefully, check tires' mean?

It means you should check the tire pressure. When aware of tire issues, the system automatically monitors tire pressure in real-time during driving and alerts for leaks or low pressure. The functions of the ABS system and tire pressure monitoring alarm are as follows: ABS System Introduction: This system compares the rotational speed differences between tires using the wheel speed sensors of the car's ABS system to monitor tire pressure. ABS determines whether a wheel is locking up through wheel speed sensors to decide if the anti-lock braking system should activate. When tire pressure decreases, the vehicle's weight causes the tire diameter to shrink, leading to changes in speed. These changes can trigger the alarm system to warn the driver. Function of Tire Pressure Monitoring Alarm: Prevents tire blowouts by monitoring tire pressure and temperature in real-time, addressing issues before they occur. Saves fuel by maintaining correct tire pressure, reducing vehicle fuel consumption. Reduces wear—insufficient pressure causes excessive wear (tire scrubbing), shortening tire lifespan.

How often should vehicles over 15 years old undergo inspection?

Vehicles over 15 years old require two inspections per year. Annual inspections can promptly identify any issues with the vehicle, allowing owners to stay informed about their vehicle's condition and carry out necessary repairs. After the revision of the motor vehicle scrappage policy, the usage lifespan restriction for private vehicles was removed, replaced by a guideline to scrap private vehicles after reaching 600,000 kilometers. However, if a private vehicle fails to obtain the relevant motor vehicle inspection certificate for three consecutive inspection cycles, it will also be subject to mandatory scrapping. Emissions Test: During the annual inspection, the vehicle's emissions will be tested for compliance, specifically focusing on the oxygen sensor and catalytic converter. Their optimal operating temperature ranges between 400 to 800 degrees Celsius, so it is recommended that owners warm up their vehicles in the external inspection area before the emissions test to increase the pass rate. Lighting Check: The vehicle management office will inspect the vehicle's lighting. If the vehicle's lights are found to be either too dim or too bright, it will be deemed unqualified and will not pass the annual inspection. It is advisable to restore the original headlights' condition before the inspection to ensure compliance.
