BMW 5 Series indicating that the battery cannot be charged reasons: Loose terminal connections: Loose or corroded terminal connections in the charging circuit increase resistance and reduce current intensity. Sulfation of battery plates: Sulfation of the battery plates causes a layer of poorly conductive white lead sulfate crystals to form on the surface. These large crystals block the pores of the plates, making it difficult for the electrolyte to penetrate, leading to increased internal resistance and preventing current flow. Excessive electrolyte specific gravity: Due to high current charging or discharging, excessive electrolyte specific gravity, or insufficient electrolyte level, the battery plates may become damaged.

What are the reasons for the non-functioning of the automatic start-stop in the Sagitar?

Vehicle not reaching the ideal working state may be due to insufficient battery charge or voltage; engine coolant temperature being too high or too low; vehicle not meeting the driver's settings, with the set air conditioning temperature differing too much from the interior temperature; during low-speed driving, the starting speed not reaching 5 km/h, or repeated acceleration with speed below 15 km/h. Here is additional information: 1. Automatic Start-Stop: Engine automatic start-stop automatically shuts off the engine when the vehicle comes to a temporary stop during driving. When moving forward again, the system automatically restarts the engine. The engine automatic start-stop intelligent fuel-saving system is a set of systems that control engine start and stop. 2. Battery: Automatic start-stop primarily relies on the battery's capacity. Since starting a car consumes a large amount of power due to the high current, vehicles equipped with this function use high-capacity batteries resistant to high-current impacts. When the battery charge drops to a certain level and can no longer provide the required high current, the automatic start-stop function will automatically disable to protect the battery's lifespan.

Does a 15-year-old vehicle need to undergo on-site inspection for the 2021 annual check?

Yes, the motor vehicle needs to undergo on-site inspection. For a motor vehicle registered in 2015, it has reached the six-year usage period by 2021 and requires on-site inspection. For the on-site inspection of the motor vehicle, you need to bring the vehicle registration certificate, the owner's ID card, and the compulsory traffic insurance policy of the motor vehicle. Here is some additional information: Compulsory Traffic Insurance (CTI): The CTI policy to be carried must be the current year's vehicle CTI. It is essential to purchase the CTI for the motor vehicle in advance to ensure seamless coverage. Vehicle insurance can be purchased up to three months in advance. The CTI is part of the mandatory insurance series, and vehicles without CTI are not allowed on the road. Inspection Failure: If the motor vehicle fails the on-site inspection, it must be repaired based on the reasons for the failure. Within the specified repair period, the vehicle is allowed to undergo re-inspection up to three times. Exceeding the number of re-inspections or the repair period will result in the invalidation of the current annual inspection for the motor vehicle. To re-inspect the vehicle, you will need to pay the fees and complete the procedures again.

Should You Use Internal or External Air Circulation When Turning on the Car Heater?

When turning on the car heater, it is recommended to use the external air circulation mode. Internal circulation is used to block out polluted air, while external circulation is for bringing in fresh air. The specific choice depends on the situation. In winter, if you want to quickly warm up the car interior, you can first start the engine and drive normally for a while to allow the engine to warm up. Once the temperature gauge needle reaches the middle position, turn on the heater with internal circulation. Using internal circulation allows the air conditioning system to rapidly cool or heat the car interior. This not only warms up the car quickly but also avoids placing extra burden on the engine, resulting in better fuel efficiency. Although continuous internal circulation keeps the car warm, the interior becomes a relatively sealed environment. Prolonged exposure to such conditions can lead to oxygen deprivation. Therefore, it's best to switch to external circulation every hour to draw in fresh air from outside. The air then passes through the air conditioning evaporator or heater core to deliver either cool or warm air. External circulation is generally recommended in most situations, especially during long-distance driving. If internal circulation is used for too long, fresh air cannot enter the car, and the same air keeps recirculating. As oxygen levels decrease, passengers may feel drowsy, and the driver may become even more fatigued, potentially leading to oxygen deprivation.

What is the method to prevent crossing the line at a curved exit?

The method to prevent crossing the line when exiting a curved path is to start turning the steering wheel back when the vehicle body is about to align with the lane line. Here are some tips for navigating curves: 1. Approach the test area: When the in-car voice prompt starts, drive the vehicle to the entrance of the curve, adjust the vehicle to the center of the road, and try to keep the outer front wheel close to the right edge of the curve. 2. Enter the curve zone: Drive the vehicle close to the right side. When the left front corner aligns with the right edge line, turn the steering wheel one full turn to the left while making minor adjustments, and observe the distance between the wheel on the right rearview mirror and the curve edge. 3. Complete the right edge line: Keep the steering wheel steady until the right vertex of the hood touches the left edge line of the right turn, then straighten the steering wheel and move forward slowly. When the left 1/3 of the hood touches the left edge line, turn the steering wheel one full turn to the right while making minor adjustments to align the right front corner with the left edge line of the right turn. Follow the S-curve to the right, and the vehicle will not cross or leave the line. 4. Exit the S-curve: When the hood is aligned with the exit, quickly straighten the steering wheel and continue driving out of the curve test area.

How to Check if a Car is New?

Check the production date on the car's dedicated nameplate to determine if it is new. If the production date is far from the present, it may indicate that the car is a stock vehicle, display car, or refurbished test drive vehicle. Below are details on how to determine if a car is new: 1. Check the car's nameplate: The nameplate contains various information, including the engine model, engine displacement, and the car's production date. 2. Inspect the windshield: The production date of the windshield can usually be found in the corner. Unless the windshield has been replaced due to damage, this date should not differ significantly from the car's overall production date. 3. Look at the VIN (Vehicle Identification Number): Located below the windshield, the VIN is a 17-digit code, commonly referred to as the chassis number. It consists of three main parts: the World Manufacturer Identifier (positions 1-3), the Vehicle Descriptor Section (positions 4-9), and the Vehicle Identifier Section (positions 10-17). Pay special attention to the 10th digit, which indicates the manufacturing year. If this year is significantly earlier than the current year, the car may be long-stocked inventory. 4. Examine the engine: A new car's engine compartment is typically clean, starts quickly, runs smoothly without shaking, and produces minimal vibration when touched. Inside the car, the engine noise should be barely audible.
