The sudden failure of the Tiguan to start may be due to human operational reasons, such as a dead battery, empty fuel tank, or incorrect gear position. Many cases of failure to start encountered in daily life are caused by improper operation or the following reasons: 1. The fuel pump is broken or there is no fuel, preventing fuel supply—check the car's fuel gauge; 2. The engine is broken and needs to be replaced; 3. The battery is dead or depleted. Solutions for failure to start: Find another car to start, connect the batteries of both cars in series to start the vehicle. In case of a depleted battery, driving the car for more than 30 minutes will allow the car's alternator to automatically charge the battery. If it doesn't charge, it indicates the battery is broken and needs to be replaced. The Tiguan is a compact SUV from SAIC Volkswagen, equipped with a 1.8T L4 engine and a 6-speed automatic transmission. The engine has a maximum horsepower of 160 PS and a maximum torque of 250 Nm. The Tiguan's body dimensions are 4506mm in length, 1809mm in width, and 1685mm in height, featuring a turbocharged intake form.

Recently, my Tiguan also had trouble starting, which was really annoying. Possible reasons include a dead battery, especially in cold weather when batteries age faster. Or the battery terminals might be corroded, causing poor contact. Additionally, there could be an issue with the starter, such as hearing only a clicking sound when trying to start but the engine won't turn over. The fuel system might also be faulty, like a non-working fuel pump that fails to supply fuel to the engine. It's recommended to first check if the dashboard lights are on—if they are, it means the battery still has power, and you can try jump-starting. If that doesn't work, it's best to call a tow truck and take it to a repair shop for inspection rather than forcing a start and risking damage to the car. Regular maintenance and replacing the battery periodically can prevent these issues, and safe driving is crucial.

How to Distinguish the Authenticity of a Driver's License?

Methods to distinguish the authenticity of a driver's license: 1. Check the anti-counterfeiting mark: There is a significant difference between the anti-counterfeiting marks of genuine and fake driver's licenses. The anti-counterfeiting mark on a genuine license features the word "China" in a dot matrix pattern, composed entirely of dots and appearing blurry; whereas a fake license uses vector graphics with block-like strokes that appear clearer. 2. Examine the font: Check if the handwriting, color, and material on the main and secondary pages of the license are consistent. Inconsistencies indicate a fake license. Besides the printed font, look for noticeable pinpricks in the text. Additionally, observe special fonts; the English translation below "People's Republic of China Motor Vehicle Driver's License" includes the word "CHINA," where the letter "A" uses a special font visible under a magnifying glass. 3. Inspect the laser anti-counterfeiting mark on the plastic seal: The upper right corner of the license displays the words "China," "CHINA," "Driver's License," and "DRIVING LICENSE," which are clearly visible when tilted under light. The lower right corner features a distinct five-pointed star, and the laser star must overlap the photo. 4. Check the secondary page: The patterns on the secondary page should align seamlessly with those on the main page. If they don't, the license is fake.

What to Do When All 12 Points of a C1 Driver's License Are Deducted?

C1 driver's license has all 12 points deducted, at this time you need to study and take a test to clear the points. The specific process is as follows: 1. When a C1 driver's license has 12 points deducted, the license will be suspended: At this time, you need to go to the traffic management department of the public security authority at the place where the motor vehicle driver's license was issued or where the driver's illegal behavior occurred to undergo a 7-day (8 hours per day) study of road traffic safety regulations. Of course, the total study hours generally need to be completed within 15 days. 2. Then take the subject one test: After passing the test (90 points), the points will be cleared and the driver's license will be reissued. For those who fail the test, they need to reschedule and take the test again until they pass. 3. The test content is determined based on the points deducted: For those who have more than 12 points but less than 24 points deducted within one scoring cycle (one year), they need to take the subject one test; for those who have 24 points deducted, in addition to taking subject one, they also need to pass the subject three test to retrieve their driver's license.

What grade of gasoline should the new Highlander use?

The new Highlander should use 95-octane gasoline, as this is the recommended grade specified in the vehicle's official user manual. In addition to checking the appropriate gasoline grade in the user manual, you can also find it marked on the fuel tank cap of the new Highlander. Generally, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92-octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95-octane gasoline. If the compression ratio is higher, 98-octane gasoline is recommended. However, with the application of new technologies, the gasoline grade cannot be solely determined by the compression ratio. High compression ratio engines can also be tuned to use lower-octane gasoline due to other influencing factors such as ignition timing, turbocharging technology, and Atkinson cycle technology. Generally, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. If the new Highlander occasionally uses the wrong gasoline grade, simply switch back to the correct grade after consumption. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower-octane gasoline, using a higher grade will not cause damage, but the increased octane number can alter the fuel's ignition point, leading to delayed combustion in the engine. This results in reduced engine power and thermal efficiency, with the actual experience being poorer performance. For vehicles recommended to use higher-octane gasoline, using a lower grade can cause engine knocking. Because the octane number is too low, the reduced ignition point may cause premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance will be generated during the upward stroke. This resistance makes the engine run very unstable. If the knocking is mild, it may only increase noise without significant engine damage. However, noticeable knocking indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.

Can Tree Sap Corrode Car Paint?

Tree sap can damage car paint. Here is some relevant information about tree sap: 1. Introduction: Tree sap contains acidity. Any acidic or alkaline liquid can cause damage to car paint. The film-forming substance in car paint is usually polyurethane. Strong acids and alkalis corrode paint by reacting with the resin or pigment fillers in the paint, causing it to deteriorate. Initially, the paint will lose its luster, then gradually corrode, and in severe cases, it may even corrode the car's body. 2. Precautions: Not only tree sap, but also bird droppings and air conditioning condensation can damage car paint.

What happens if you drive dozens of kilometers without coolant?

If you drive dozens of kilometers without coolant, the engine temperature will continue to rise without the cooling effect of the coolant, which can easily lead to overheating. In severe cases, it may cause engine damage. It is recommended to pull over immediately and stop driving. Turn off the engine to allow it to cool down, and only resume driving after the engine temperature has decreased. Avoid prolonged driving and replenish the coolant promptly. More relevant information is as follows: 1. Function of coolant: Coolant is an essential fluid for cars. Antifreeze serves multiple purposes, including preventing freezing, cooling, corrosion resistance, and scale prevention. It ensures the car can operate normally in cold climates without freezing and helps cool down the high-temperature engine. 2. Consequences of losing coolant: A lack of coolant means the engine and radiator lose protection. Insufficient coolant affects the radiator's cooling efficiency, preventing it from achieving the necessary cooling effect. This disrupts the normal circulation of coolant, leading to high temperatures and, in severe cases, engine burnout. In cold climates, it can also cause the engine or radiator to freeze, resulting in engine failure and rendering the vehicle unusable.
