The sunroof leakage in the Tiguan may be caused by the following three reasons: 1. The sunroof drain outlet is blocked by debris: This prevents rainwater from draining out, causing it to gradually seep into the vehicle. Clean the drain outlet with a towel to ensure rainwater drains smoothly to the ground. 2. Damaged sunroof seal: This leads to poor edge sealing, allowing rainwater to enter the vehicle. For a damaged sunroof seal, it is necessary to replace it with a new one. 3. Gaps in the Tiguan sunroof frame: This allows rainwater to seep into the vehicle. If the vehicle is still under warranty, the most straightforward solution is to replace the sunroof frame.

Is it okay not to change the engine oil for a long time?

It is not advisable to not change the engine oil for a long time. The reasons are as follows: 1. Reduced sealing effect. High-quality engine oil with appropriate viscosity can effectively seal the gaps between the cylinder block and pistons, preventing gas leakage. If the oil is not changed for a long time, it will become watery and lose its sealing function. 2. Reduced lubrication effect. The lubrication system is crucial to the engine, affecting its performance and service life. If the oil is not changed for a long time, its lubrication effect will significantly decrease. 3. Reduced cooling effect. The heat absorption and conduction properties of oil are much higher than those of water. If the oil deteriorates severely, its heat dissipation function will be greatly reduced. 4. Increased wear of components. If the engine oil is not changed for a long time, it will become ineffective and deteriorate. Instead of protecting the components, it will increase wear and damage. 5. Corrosion of internal components. If the oil is not changed for a long time, it will accumulate many impurities, such as iron filings, and may also cause corrosion of internal components. 6. Further damage to the engine.

What is the function of the compression ring?

Compression rings, also known as piston rings, serve to ensure the seal between the piston and the cylinder wall, preventing high-temperature, high-pressure combustion gases in the cylinder from leaking into the crankcase. Additionally, they transfer the majority of the heat from the piston crown to the cylinder wall, which is then dissipated by cooling water or air. The four main functions of compression rings are as follows: 1. Oil control function: They evenly distribute the oil splashed or sprayed onto the cylinder wall and scrape off excess oil. The scraped oil flows back to the crankcase through the gap between the piston and cylinder liner and the oil drain holes in the piston grooves. The oil ring controls 70% to 90% of the oil, while the compression rings control 10% to 20%. 2. Support function: During the synchronous reciprocating motion of the piston and piston rings, the piston exerts a significant normal force (reciprocating inertia force) on the piston rings. When the connecting rod exerts a side force on the piston, causing it to tilt, the piston rings apply a frictional reaction force due to the normal force, thereby supporting the piston. 3. Heat conduction function: Approximately 70% of the heat from the piston is conducted through the piston ring faces to the cylinder wall, with the top and second rings playing the primary role in heat conduction, ensuring the piston's thermal balance. 4. Sealing function: During the compression and power strokes, the piston rings seal the downward-moving gases. The top ring seals 80% to 90% of the gases, the second ring seals 10% to 20%, and the third ring (oil ring) seals about 5% of the gases.

How Much Does It Cost to Replace the Battery of a New Energy Vehicle?

For a pure electric vehicle with a range of over 300 kilometers, the weight of the battery alone exceeds 500kg, and the cost of replacing the battery is close to 100,000 yuan. Therefore, if there is a problem with the battery, the price of replacing it can be very expensive. For example, the Roewe 550 plug-in hybrid model has a battery replacement cost of 95,000 yuan, which is more than 50% of the car's price. Additional Information: 1. Currently, all new energy vehicle models launched by domestic automakers comply with the national regulations regarding lifespan and mileage, with some even exceeding the national standards. For instance, BAIC extends the warranty for the battery, motor, and electronic control to 6 years or 150,000 kilometers on top of the standard 5-year or 100,000-kilometer warranty for the entire vehicle, while BYD offers a lifetime warranty for the battery. From the perspective of industrial scale development and marginal cost reduction, the cost of battery replacement will gradually decrease. 2. The era of fuel-powered vehicles will gradually fade from the automotive stage. Countries around the world have now set clear timelines for banning the sale of fuel-powered vehicles, making new energy vehicles the inevitable trend of the future. New energy battery technology will also continue to improve and develop rapidly, making battery replacement more affordable in the future.

What to Pay Attention to When Replacing a Car Battery

When replacing a car battery, pay attention to the following points: 1. The battery must be securely installed. Regularly check whether the battery is firmly in place, including inspecting the battery connection wires and terminals for tightness and ensuring good contact between the wires and terminals. Otherwise, when driving on bumpy roads, the battery may shake or even fall off and get damaged, and loose connection wires could potentially generate sparks. 2. Limit the cranking time to 3-5 seconds each time. If the car doesn't start on the first attempt, wait at least 15 seconds before trying again. If the car still doesn't start after multiple attempts, avoid prolonged cranking and look for other potential issues. Prolonged high-current discharge can severely damage the battery's internal structure. 3. Avoid running the air conditioning while the car is idling. When the engine is idling, the alternator does not produce enough power to support the air conditioning, forcing the system to draw power from the battery itself, which accelerates battery wear. 4. Maintain cleanliness and prevent rust. Promptly clean any oxides or sulfates that form on the battery terminals. Apply petroleum jelly after scraping off rust to prevent further corrosion. Also, regularly remove dust, dirt, and spilled electrolyte from the battery cover, as well as any oxides or sulfates on the terminals. 5. Do not replace the original battery with one that has a higher capacity. The car's alternator has a fixed power output, so installing a higher-capacity battery may result in insufficient charging, making it difficult to start the car and causing the battery to degrade faster due to chronic undercharging.

What Causes the Car Door Window to Automatically Descend After Reaching the Top?

Car has changed the position of the anti-pinch function, and it can be fixed by readjusting the anti-pinch position at the 4S shop. Here is some information about the anti-pinch function: 1. The window anti-pinch function is a safety feature on vehicles, which means that when the electric window glass is closing, it will automatically stop or change the upward movement to a downward movement when encountering resistance, thereby preventing pinching and protecting the safety of the occupants. 2. The window anti-pinch controller not only enhances the safety of the car and improves its grade, but also greatly extends the service life of the electric window.

How to Reset the Tire Pressure on the New Magotan?

New Magotan tire pressure alarm reset: Operate the buttons on the multifunction steering wheel, and use the "Tire Pressure" option in the multifunction menu to reset the tire pressure status; There is a tire pressure reset switch on the side of the gear lever. With the ignition switch on, press and hold the switch button until you hear a beep, indicating the reset is complete. According to the international GBT2978-2008 standard, the recommended tire pressures for different tires are as follows: Standard tires: 2.4-2.5bar; Reinforced tires: 2.8-2.9bar; Maximum pressure: Should not exceed 3.5bar. If the tire pressure exceeds the normal value, drive slowly to a stop and have it checked nearby.
