Why does the fan keep running after the Tiguan is parked?

Tiguan's fan continuing to run after parking is a normal phenomenon. The Volkswagen Tiguan uses a turbocharged engine. The biggest hazard of this engine's turbocharging system is that after the vehicle is parked, the engine stops running for a period of time, and the turbocharging system cannot dissipate heat. This can cause the turbo's oil seal to burn out. Over time, the turbo system will lose lubricating oil, leading to complete damage of the vehicle's turbocharging system. To compensate for this deficiency, the vehicle continues to run the fan after the engine is turned off, increasing the cooling time for the intercooler of the turbocharging system. This effectively extends the lifespan of the turbocharging system. Precautions for using a turbocharged engine: 1. Do not drive off immediately after starting: After starting the engine, especially in winter, let it idle for a while to allow the lubricating oil to fully lubricate the bearings before the turbocharger rotor operates at high speed. Therefore, avoid revving the engine hard immediately after starting to prevent damage to the turbocharger oil seal. 2. Do not turn off the engine immediately: After the engine has been running at high speed for a long time, do not turn it off immediately. During operation, part of the engine oil is used to lubricate and cool the turbocharger rotor bearings. 3. Keep it clean: When disassembling the turbocharger, maintain cleanliness. All pipe connections should be plugged with clean cloth to prevent debris from entering the turbocharger and damaging the rotor. During maintenance, be careful not to damage the impeller by collision. If the impeller needs to be replaced, perform a dynamic balance test. After reassembly, remove any plugs. 4. Perform regular cleaning: Since the turbocharger often operates at high temperatures, the lubricating oil lines can develop partial carbon deposits due to the heat, which may lead to insufficient lubrication of the turbocharger bearings and cause damage. Therefore, the lubricating oil lines should be cleaned periodically. 5. Pay attention to inspection and maintenance: Before driving and after parking, check the connections of the air ducts to prevent loosening or detachment, which could cause the turbocharger to fail or allow air to short-circuit into the cylinders.

What is the state of people inside a vehicle when it suddenly brakes while moving?

When a normally moving car suddenly brakes in an emergency, the lower body of the people inside stops with the car, while the upper body continues to move forward due to inertia, maintaining its original state. This is because the passengers have inertia, not the car. Introduction to braking: Braking, also known as stopping, refers to the action of stopping or reducing the speed of moving locomotives, vehicles, and other transportation tools or machinery. Principle of braking: The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine and install corresponding brake shoes, belts, or discs on the machine base, which generate braking torque under external force. The braking device, also known as a decelerator, is a mechanical braking device that can slow down the speed.

Does a new car need annual inspection in 4 years?

New cars require annual inspection in the fourth year, which falls under regular periodic inspection. Below are the materials required for vehicle inspection: 1. For individual vehicle inspection: Original vehicle license, copy of compulsory traffic insurance, ID card copy, and the vehicle itself. 2. For company vehicle inspection: Original vehicle license, copy of compulsory traffic insurance, Organization Code Certificate of the People's Republic of China (with fresh seal), Power of Attorney (with fresh seal), agent's ID card copy, and the vehicle itself. Note: Vehicles eligible for exemption from inspection and issuance of inspection qualification marks only need to visit the vehicle management office, motor vehicle registration service station, or traffic police squadron to fill out the "Motor Vehicle Inspection Mark Application Form" and then receive the motor vehicle inspection qualification mark and vehicle license.

Is It Normal for the Warning Light to Illuminate in a New Car?

When the ignition switch is turned on, the dashboard indicator lights will illuminate as part of the vehicle's self-diagnostic system. These lights should automatically turn off after a short period. If any of the following warning lights remain on, it indicates a potential system malfunction that requires prompt inspection to avoid safety hazards. Here are the common reasons for warning lights in new cars: 1. Sensor malfunction: This could be due to loose sensor wiring or a faulty sensor that needs inspection or replacement. 2. Engine carbon buildup: Significant carbon deposits in the engine require cleaning. Poor-quality fuel can lead to incomplete combustion, which the emission monitoring system will detect. In such cases, simply refueling with the correct grade of fuel should resolve the issue. It's advisable to promptly visit a repair shop to check the fault codes when a warning light appears, as some problems can only be accurately diagnosed through computer scanning.

How long must one purchase a car after obtaining a Beijing new energy vehicle license?

If a car is not purchased within 6 months, the license will become invalid and must be reapplied. Below is relevant information about new energy vehicles: 1. Introduction: New energy vehicles refer to automobiles that utilize unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new onboard power devices), integrating advanced technologies in vehicle power control and driving systems to form automobiles with advanced technical principles, new technologies, and novel structures. 2. Classification of new energy vehicles: New energy vehicles, also known as alternative fuel vehicles, include pure electric vehicles and fuel cell electric vehicles that entirely use non-petroleum fuels, as well as hybrid electric vehicles and ethanol gasoline vehicles that partially use non-petroleum fuels. All existing new energy vehicles fall under this concept and are specifically categorized into six types: hybrid vehicles, pure electric vehicles, fuel cell vehicles, alcohol ether fuel vehicles, natural gas vehicles, etc.

What are the reasons for no internet connection in the car?

Reasons for no internet connection in the car are as follows: 1. Reason one: The computer system is outdated, with system file versions being too low, resulting in insufficient compatibility and support for new software, causing compatibility lag. 2. Reason two: Too many background processes and startup items running on the computer, leading to insufficient memory. 3. Reason three: Insufficient physical memory in the computer, with memory sticks becoming unstable due to aging or voltage issues. 4. Reason four: CPU processes are overloaded, exceeding the maximum capacity the CPU can handle, causing data processing failures. 5. Reason five: High ambient temperatures in summer, poor internal ventilation in the machine, and excessive usage causing the CPU temperature to rise.

What are the hidden dangers of converting halogen headlights to xenon headlights?

Converting halogen headlights to xenon headlights is most likely to cause vehicle self-ignition, especially when privately installing low-quality xenon lights. This is because modified xenon lights generate extremely high temperatures, while the headlight housing has a limited heat resistance capacity. The reflective panels inside the housing are particularly prone to melting, which can lead to vehicle self-ignition. Ensure neat wiring during modification: Avoid excessively long dangling wires and friction from movement. Make sure all wire connections are secure and insulated. Avoid installing excessive decorative lighting: Throughout the modification process, pay careful attention to every detail and ensure all safety measures are properly implemented. Self-ignition can be prevented, especially since xenon lights, apart from having higher initial startup current, generally operate at lower power than halogen bulbs.
