Does the Timing Chain of the Old Tiguan Need to Be Replaced?

The chain also needs to be replaced, but not on a regular basis. It should be replaced based on actual conditions—when there is a malfunction or abnormal noise. If there are no issues, replacement is unnecessary. The chain won't break, but it may stretch. When stretched or if the tensioner malfunctions, the chain may skip teeth, which can damage the engine by impacting the valves. Functions of the timing chain: 1. Drive the engine's valve train: It ensures the intake and exhaust valves open or close at the right time, allowing the engine cylinders to intake and exhaust normally. 2. Drive: Chain-driven systems are reliable, durable, and space-saving. The entire system consists of gears, chains, and tensioning devices. The hydraulic tensioner automatically adjusts the tension, maintaining consistent chain tension and requiring no maintenance throughout its lifespan, making it as durable as the engine itself. 3. Robust and durable: Timing chains have inherent durability, offering peace of mind without concerns about "long-term neglect" or "breaking down at critical moments." However, when the vehicle's total mileage reaches 100,000 kilometers, the drawbacks of the timing chain begin to emerge.

Is it a problem if the car key is dropped?

You can try using the remote control; if it works, then it's not broken. The chip inside the key is relatively fragile, so be careful not to drop it frequently. Dropping it occasionally is fine. Below are solutions for what to do if you lose your car key: 1. Use the spare key: Generally, cars come with two keys, one for regular use and the other as a spare. If the regular key is lost, the spare key can be used. Therefore, it's important to remember not to keep the spare key in the car; always store it in a safe place at home. Otherwise, if the regular key is lost and the spare key is also in the car, you'll have to call a locksmith. 2. Professional locksmith services: If the car is far from the spare key or the spare key is also lost, you should contact a professional locksmith company to unlock the car. Usually, you'll need to provide proof that the car belongs to you, such as an ID card or vehicle registration. 3. Visit a 4S shop: Every car comes with an anti-theft code. By providing the vehicle registration and personal information to the 4S shop, they can retrieve the anti-theft code and configure a new key. Additionally, they can erase the data of the lost key, rendering it invalid for starting the car (though it may still open the door). Therefore, the 4S shop may also recommend replacing all the locks for added security.

What Causes Intermittent Cooling in Car Air Conditioning?

Intermittent cooling in car air conditioning may be caused by issues with the air conditioning heat dissipation, blower performance, or blower resistor. Below are the specific details: 1. Air conditioning heat dissipation: Inspect the surface of the air conditioning condenser for any debris that may affect heat dissipation. Otherwise, the air conditioning compressor may shut down due to excessive temperature, leading to the aforementioned poor cooling effect and temperature sensation. 2. Blower performance: Conduct a performance check on the air conditioning blower. The method involves dismantling the blower and rotating the fan blades to check for any resistance. If resistance is found, replace the blower. 3. Blower resistor: If the blower resistor is malfunctioning, it can also cause the aforementioned phenomenon. A common case is normal performance at high fan speeds but poor performance at low speeds. If this is the issue, replace the resistor.

Can dashboard wax be sprayed on leather seats?

Dashboard wax can be sprayed on leather seats. Dashboard wax mainly serves a protective function, preventing aging. As an interior polish, it can restore the original color and reveal a natural luster. It is suitable for use on leather seats. Dashboard wax, also known as polish, can be sprayed on the dashboard as well as other surfaces to enhance brightness. Here is some relevant information about dashboard wax: 1. Dashboard wax, also called instrument wax, is a specialized care product for automotive leather trims, dashboards, and other components. It effectively prevents aging of the dashboard and interior parts while offering features like dirt removal, anti-static properties, and UV protection. 2. It can quickly restore the natural shine and texture of car leather seats and interior headliners, keeping them fresh and soft. It also makes dashboards and tire surfaces look bright and new. 3. It provides excellent dust, dirt, and rust prevention. Additionally, the good lubricating properties of dashboard wax prevent surfaces from becoming rough, ensuring a highly glossy finish. Dashboard wax (450ml) is suitable for dashboards, leather, and tires, offering dirt removal, polishing, and protection in one application.

Is it harmful to the car if I don't refuel when the fuel light comes on?

Not refueling when the fuel light comes on is not harmful to the car, as long as you don't run out of fuel and stall the engine. The fuel gauge light is just a warning; when it lights up, there is still some fuel left in the tank, generally enough to drive about 50-100 kilometers. However, it's advisable to refuel as soon as the light comes on and avoid the risk of running the tank dry, as this can damage the fuel pump and cause inconvenience. Additional information: 1. It's often said that you shouldn't wait until the fuel light comes on to refuel, as it can harm the car. The concern is primarily about the fuel pump, which is normally submerged in gasoline to dissipate heat. When the fuel level is low, it can't dissipate heat effectively. However, this is not actually the case—it doesn't affect the car, and the fuel light is simply a reminder for the owner to refuel. 2. The fuel pump does require cooling, but it doesn't rely on the surrounding fuel for heat dissipation. There are two reasons for this: 1) If it relied on the surrounding fuel for cooling, the temperature of the gasoline in the tank would keep rising, posing a potential hazard. 2) The fuel pump is quite tall, spanning the entire height of the fuel tank, with the motor located in the middle-lower part. When only one-third of the fuel remains, the motor is no longer submerged in gasoline.
