What is the reason for the engine malfunction light coming on and then turning off?

Why can't you sleep in the car with the air conditioning on but you can drive?

The following are the reasons why you cannot sleep in the car with the air conditioning on: If you close the doors and windows and turn on the air conditioning, the car becomes a confined space. Sleeping in a confined space can lead to the following hazards. Here are some explanations about sleeping in the car with the air conditioning on: 1. Safety hazards: When the car is stationary, the exhaust fumes produced are not blown away by the wind as they would be when driving. These fumes can easily be drawn into the car by the air conditioning system, leading to carbon monoxide poisoning. If the car remains closed for a long time, the oxygen level inside will gradually decrease, making it easy to suffocate while sleeping. Therefore, sleeping in the car with the air conditioning on is unsafe. 2. Precautions: If you must sleep in the car, it is best to use the air conditioning's external circulation mode. This mode draws in air from outside the car, keeping the air inside circulating.

How to Disassemble a Volkswagen Car Remote?

Here is the method to disassemble a Volkswagen car remote: 1. Open the folding part of the key, pop out the mechanical key, insert a flat-head screwdriver into the horizontal slot in the groove, apply firm pressure, and then use a skillful twist to turn the screwdriver. 2. Once a larger gap is created, hold onto the keyring below and pull hard to separate the key into upper and lower parts. 3. Forcefully pry open the side to split this part of the key into front and back pieces. 4. Expose the battery section and the circuit board section, remove the old battery and replace it with a new one, then reassemble everything in the original order. Notes: 1. The outer shell of the remote key is generally not waterproof, so never soak the remote key in water as it may damage the chip. 2. When using the remote key in daily life, try to avoid remote control from a long distance, as it will increase battery consumption.

What are the main reasons for difficult hot-starting of a car?

The main reasons for difficult hot-starting of a car are: 1. The more severe the fuel injector leakage, the richer the air-fuel mixture becomes, leading to difficult hot-starting; 2. Damaged carbon canister purge valve: During hot-starting, fuel atomization is normally sufficient without additional fuel vapor supply. If the carbon canister continues to supply fuel vapor to the intake tract, it will cause an overly rich mixture, resulting in difficult starting; 3. Poor fuel quality: Especially in winter when temperatures are low, the engine block temperature during cold starts is low, making fuel atomization difficult. This prevents the fuel injected into the cylinders from fully mixing with air, causing starting difficulties; 4. Damaged intake air temperature sensor; 5. Engine carbon deposits: Carbon deposits have a strong adsorption effect on gasoline. If there are excessive carbon deposits on intake valves, throttle valves, pistons, etc., they can adsorb some fuel, leading to an overly lean mixture and affecting starting performance.

Should I swipe my ID card or pull the handbrake first in Subject 2?

You need to swipe your ID card first. Here are the relevant details: 1. Definition: Subject 2, also known as the small road test, is part of the motor vehicle driver's license examination. It refers to the field driving skills test. For cars C1 and C2, the test items include five mandatory tests: reverse parking, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving (commonly known as the S-curve). Some regions also include a sixth item: high-speed toll card collection. 2. Teaching objectives: Master the basic driving operation essentials and possess the fundamental ability to control the vehicle; proficiently grasp the basic methods of field and in-field road driving, have the ability to reasonably use vehicle control components and correctly control the vehicle's spatial position, and be able to accurately control the vehicle's driving position, speed, and route.

What is a PCV valve?

Here is an introduction to the PCV valve: 1. Introduction: PCV is the abbreviation of Positive-Crankcase-Ventilation in English, which means the active ventilation control system for the crankcase (or oil pan) in Chinese. The PCV valve consists of a valve body, valve, valve cover, and spring, and cannot be disassembled. Its main function is to direct the gases inside the crankcase into the intake manifold through the PCV valve, with a small amount of air entering the intake manifold directly from the air filter via the PCV valve. This prevents icing at the throttle, incomplete combustion, and worsening emissions. It also prevents blow-by gases from entering the atmosphere and prevents engine oil from deteriorating. 2. Principle: The PCV valve is a metering control valve installed between the engine crankcase ventilation system and the intake system. The PCV valve is controlled by vacuum to regulate the flow of oil fumes from the crankcase ventilation system into the intake system. The flow rate is higher when the engine is running at high speeds compared to low speeds. Additionally, when engine backfire occurs, the PCV valve should cut off ventilation to prevent crankcase explosion.

Why is the subject 2 test scheduled 10 days later?

Relevant regulations: After completing subject 1 and obtaining the study driving certificate, candidates for the C license can schedule the subject 2 test 10 days later, while those for the A or B license must wait 20 days. According to Article 139 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses" by the Ministry of Public Security: 1. Article 17: For first-time applicants or those applying to add a permitted driving type, the vehicle management office shall issue a study driving certificate within one day after passing the subject 1 test. 2. Article 40: For first-time applicants or those applying to add a permitted driving type, the following conditions must be met to schedule the subject 2 test: (1) For small cars, small automatic transmission cars, low-speed trucks, three-wheeled cars, small automatic transmission passenger cars for the disabled, wheeled self-propelled machinery, trolleybuses, and trams, the test can be scheduled 10 days after obtaining the study driving certificate. (2) For large buses, tractors, city buses, medium buses, and large trucks, the test can be scheduled 20 days after obtaining the study driving certificate.
