Here are the reasons why a sedan makes a clunking sound when driving on rough roads: 1. Loose or deformed chassis components causing abnormal noise. 2. Tire-related noise, such as tread noise. 3. Abnormal noise from chassis components like the engine or transmission internal parts. 4. Noise from various transmission components and connecting parts. 5. Abnormal noise from the front or rear wheel bearings. 6. Human errors during installation, replacement, or maintenance, such as improperly tightened screws, interference between components, incorrect positioning, or reverse installation, leading to component noise. This is very dangerous. 7. Abnormal noise from critical safety components: for example, worn brake pads reaching their limit causing direct grinding noise with the disc; or lack of oil in the power steering system leading to chassis noise.

Should the Automatic Transmission Filter Be Replaced?

Automatic transmission filters need to be replaced. Generally, they should be replaced along with the transmission fluid, approximately every two years or after driving 40,000-60,000 kilometers. The conditions for replacing an automatic transmission filter are: 1. Friction between metal components generates fine debris, and the transmission fluid becomes contaminated. These impurities are easily intercepted and filtered by the transmission filter screen to prevent transmission malfunctions. 2. Most filters are made of filter paper material, which accumulates many impurities after long-term use, necessitating replacement. Additional information: The transmission filter, also known as the transmission filter screen, is installed inside the transmission and serves a filtering function. It filters out oil contaminants in the transmission, thereby protecting the transmission.

How to Adjust Toe-in?

Start the car, turn the steering wheel fully to the right, causing the left wheel to tilt outward. At this point, squat down and you can see the left wheel's toe rod exposed. Use a wrench to first loosen (tighten the screw), then turn the toe rod counterclockwise. Rotate the wrench handle 90 degrees to slightly shorten the left toe rod. Using the same method, adjust the right front wheel by turning the toe rod clockwise. Rotate the wrench 90 degrees to slightly lengthen the right wheel's toe rod. Take the car for a test drive on the road to check for any deviation in straight-line driving. If it's not accurate, make further fine adjustments.

What are the differences between built-in and external tire pressure monitoring systems?

The differences between built-in and external tire pressure monitoring systems are as follows: 1. First, there is a difference in price, with built-in systems being relatively more expensive than external ones. 2. Secondly, there are differences in installation method and time required. Installing a built-in tire pressure monitoring system takes more time and requires professional tire removal, making it generally impossible for individuals to install themselves. In contrast, external systems are simpler to install, allowing car owners to do it themselves. 3. In terms of accuracy, external systems are slightly less precise than built-in ones due to factors such as environmental conditions and external forces. 4. Regarding theft prevention, built-in systems are more secure because they are installed inside the tire, making theft highly unlikely. External systems have poorer theft prevention since the same brand typically uses the same removal tools, meaning sensors from the same brand can all be easily removed.

What to Do When the Key is Locked Inside the Tiguan?

The first thing that comes to mind is to use the spare key. You can contact a family member to deliver the spare key to the car's location and use the mechanical key to unlock it, which is a perfect solution. You can directly call the car's customer service hotline and request remote unlocking assistance. This requires a series of authentication steps and can be quite challenging. Check if the car window is completely closed. If there is a slightly larger gap, you can use a hooked wire to reach inside the window, hook the door handle, and open the door from the inside. Call a professional locksmith company and ask for assistance from a professional locksmith. Remember, it's crucial to find a qualified professional, as damaging the car lock would be counterproductive.
