TSI stands for Turbocharged Stratified Injection technology by Volkswagen. Here are specific introductions to common faults in car turbocharging: 1. Turbocharger oil leakage fault: High oil consumption but normal exhaust color with no power loss. Generally caused by oil seepage. 2. Compressor end oil leakage: High oil consumption with blue exhaust smoke but no power drop. Caused by oil entering the combustion chamber through the engine intake pipe due to compressor end leakage. 3. Excessive wear between piston and cylinder: High oil consumption with blue or black exhaust smoke and power reduction. Caused by oil entering the combustion chamber due to excessive wear between piston and cylinder. 4. Excessive bearing wear: Metal friction sound from turbocharger. Black exhaust smoke, power reduction, and abnormal noise from turbocharger. Possibly caused by excessive wear of turbocharger rotor bearings or thrust bearings, resulting in impeller friction against the turbocharger housing.

When is the time to collect the annual inspection sticker?

According to the new regulations, family-use small cars are exempt from on-site inspection for 6 years, but within those 6 years, you still need to collect the annual inspection sticker and environmental protection sticker from the vehicle management office every 2 years. Here is some extended information about motor vehicle annual inspections: 1. Legal basis: Article 32 of the "Motor Vehicle Registration Regulations" stipulates that the owner of a motor vehicle can apply for an inspection compliance mark at the vehicle management office of the registration location within three months before the expiration of the motor vehicle inspection validity period. 2. Consequences of not inspecting: If a vehicle that has not undergone the annual inspection continues to be driven on the road, it will be subject to a fine and a three-point penalty, and the vehicle will also be impounded. 3. Advance time: The annual inspection of a motor vehicle can be conducted up to three months before the expiration of the driving license. It is best to do it two months or a little over one month in advance, and not wait until there are only a few days left before the inspection expires.

What Are the Reasons for a Car Not Starting Even When the Battery Has Power?

There are many reasons why a car won't start even when the battery has power. Here is a detailed analysis and solution: 1. Wrong gear position: If the gear is in D (Drive) or R (Reverse), the car won't start. It will only start when the gear is in P (Park) or N (Neutral). 2. Out of fuel: The car won't start if it's out of fuel. 3. Fuel pump failure: If the starter motor runs normally but the car doesn't start, check the fuel lines. 4. Throttle body carbon buildup: Too much carbon buildup in the throttle body can also prevent the car from starting. In this case, slightly pressing the accelerator pedal may help start the engine.

What are the items for vehicle annual inspection?

Vehicle annual inspection items include a comprehensive check of appearance inspection, exhaust emission test, window film light transmittance, and traffic violation checks. Here is additional information about vehicle annual inspection: 1. Regulations: If a vehicle's inspection is overdue by less than 3 months, you only need to go directly to make up for it, and usually, an oral warning will be given. 2. Notes: (1) Check if the insurance policy is correct, especially for the first annual inspection of a new car. If the information on the insurance policy does not match the actual situation, go to the insurance company to correct it. (2) If you need to replace the environmental protection label, go to the environmental protection bureau's auto repair shop in advance to complete the exhaust test to save time. (3) Go to the traffic team to clear traffic violations (this must be prioritized). (4) For the annual inspection, it's better to do it early rather than late. Inspections at the beginning of each month will be faster. (5) Remember to bring money, as the annual vehicle inspection is not free. (6) Bring all required materials to avoid being unable to apply for the inspection.

Where is the cabin air filter located in the 2012 Yuexiang?

The cabin air filter of the 2012 Yuexiang is located on the passenger side. You need to lean your head under the passenger seat, specifically below the glove compartment, and look upwards. Alternatively, you can open the passenger door, lie down on the passenger floor mat, extend your head under the glove compartment, and look up to locate the screw (which secures the cabin air filter cover plate). Loosen the screw to remove the filter. More details are as follows: 1. When driving with the air conditioning on, the vehicle draws in outside air into the cabin. However, the air contains various particles such as dust, pollen, soot, abrasive particles, ozone, odors, nitrogen oxides, sulfur dioxide, carbon dioxide, benzene, etc. 2. Without the cabin air filter, these particles can enter the cabin, not only contaminating the car's air conditioning system and reducing the cooling system's performance but also causing allergic reactions, lung damage, irritation from ozone exposure, and unpleasant odors, all of which can affect driving safety.

What Should You Pay Attention to When Driving on the Highway?

Here are some precautions for beginners driving on the highway: 1. Probationary period drivers cannot drive alone on the highway: Probationary period drivers are not allowed to drive alone on the highway. New drivers often lack a sense of speed and distance, so if your driver's license is still within the probationary period, it's better to choose national roads for travel or have a driver with more than three years of experience accompany you in the passenger seat. It is advisable not to venture onto the highway until you are confident in your driving skills. 2. Thoroughly check the vehicle condition the day before departure: The biggest concern during long-distance travel is the vehicle breaking down midway. It is recommended to have a professional mechanic inspect the vehicle carefully before departure, paying special attention to critical components like tires and brake pads that are essential for long-distance driving. Preventing problems before they occur is the wise choice. 3. Control your speed: New drivers often struggle with judging speed and may easily exceed the limit, so it's crucial to control your speed. Especially when exiting the highway and entering the ramp (usually speed-limited to 40km/h), it's important to be mindful of slowing down, as many people tend to speed in the ramp.

Is an exam required for upgrading from C1 to B2 driver's license?

An exam is required. The following are the conditions for upgrading from C1 to B2: Hold a C1 driver's license for small cars for more than 3 years, with no full-point records in the last three consecutive scoring cycles, aged between 20 and 50, no record of causing a fatal traffic accident with equal or greater responsibility; no record of drunk driving; and no revocation or cancellation of the driver's license within the last ten years. C1 is a code for a type of driver's license. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" (Ministry of Public Security Order No. 123), C1 refers to a driver's license that permits driving small and micro passenger vehicles, light and micro cargo vehicles, as well as light and micro special-purpose vehicles. It also permits driving vehicles under the C2, C3, and C4 license categories. A B2 driver's license allows driving heavy and medium-duty cargo vehicles or large, heavy, and medium-sized special-purpose vehicles. Heavy and medium-duty cargo vehicles are mostly trucks, such as the large dump trucks commonly seen on roads, which belong to heavy trucks. Large, heavy, and medium-sized special-purpose vehicles refer to vehicles equipped with special equipment or devices, such as water sprinklers, concrete mixers, fire trucks, etc. Article 14 of the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" states that for first-time applicants of a motor vehicle driver's license, the permitted vehicle types include city buses, large trucks, small cars, small automatic transmission cars, low-speed cargo vehicles, three-wheeled cars, small automatic transmission passenger cars for the disabled, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, light motorcycles, wheeled self-propelled machinery, trolleybuses, and trams. For those who already hold a motor vehicle driver's license and apply to add permitted vehicle types, the additional permitted vehicle types include large buses, tractors, city buses, medium-sized buses, large trucks, small cars, small automatic transmission cars, low-speed cargo vehicles, three-wheeled cars, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, light motorcycles, wheeled self-propelled machinery, trolleybuses, and trams. Article 15 states that for those who already hold a motor vehicle driver's license and apply to add permitted vehicle types, there should be no record of accumulating 12 points in the current scoring cycle and the most recent scoring cycle before the application. For applications to add medium-sized buses, tractors, or large buses to the permitted vehicle types, the following additional regulations apply: For applications to add medium-sized buses to the permitted vehicle types, the applicant must have held a license for city buses, large trucks, small cars, small automatic transmission cars, low-speed cargo vehicles, or three-wheeled cars for more than three years, with no record of accumulating 12 points in the last three consecutive scoring cycles before the application. For applications to add tractors to the permitted vehicle types, the applicant must have held a license for medium-sized buses or large trucks for more than three years, or held a license for large buses for more than one year, with no record of accumulating 12 points in the last three consecutive scoring cycles before the application. For applications to add large buses to the permitted vehicle types, the applicant must have held a license for city buses, medium-sized buses, or large trucks for more than five years, or held a license for tractors for more than two years, with no record of accumulating 12 points in the last five consecutive scoring cycles before the application. Full-time students receiving driving vocational education who have obtained a license for small cars while in school and have no record of accumulating 12 points in the current scoring cycle and the most recent scoring cycle before the application can apply to add large buses or tractors to their permitted vehicle types.
