Can a BMW run with one liter less engine oil?

What does it mean when the engine yellow light on the dashboard is on?

The reasons for the engine yellow light on the dashboard being illuminated are as follows: 1. Sensor issues: Sensors include those for coolant temperature, crankshaft position, air flow, intake air temperature, oxygen, etc. When these sensors are damaged, have poor contact, or experience signal interruption, the vehicle's ECU cannot accurately obtain engine data, which will trigger the engine fault light. 2. Maintenance issues: Poor engine maintenance is the most common cause of the engine fault light coming on. 3. Fuel and oil quality issues: The quality of fuel and engine oil matters. The fuel added to a car usually has a specific grade, and engine oil can be semi-synthetic or fully synthetic. If the owner does not follow the required specifications for these, it can lead to engine wear over time. 4. Poor combustion of the air-fuel mixture: Faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines can all cause poor combustion of the air-fuel mixture in the engine. This can lead to engine carbon buildup or knocking, which the engine's oxygen sensor will detect and report to the ECU, triggering the fault light as a warning. 5. Air intake issues: The engine requires air intake during combustion, making the air filter crucial. If the car's air filter is dirty and not cleaned regularly, it can affect the engine's air intake, potentially leading to blockages over time. In severe cases, this can cause the engine fault light to illuminate.

What are the precautions after replacing brake pads?

After installing new brake pads, it is necessary to break them in. The relevant precautions are as follows: 1. Find a place with good road conditions and few vehicles to start the break-in process. Accelerate to 60 km/h, gently apply the brakes, and use moderate braking force to reduce the speed to about 10 km/h; 2. Release the brakes and drive a few kilometers to allow the brake pads and discs to cool slightly, then repeat the above steps at least 10 times; 3. The broken-in brake pads still require several hundred kilometers of driving to achieve optimal performance with the brake discs. During this period, drive carefully to prevent accidents.

Which is Larger: Compact or Small?

Compact SUVs are generally larger than small SUVs. Here is an introduction to both types: 1. The body length of a small SUV ranges from 3580 mm to 4350 mm, with a wheelbase of over 2670 mm, while the body length of a compact SUV ranges from 4300 mm to 4750 mm, with a wheelbase of approximately 2600-2760 mm. 2. Currently popular compact SUV models include the Haval H6, Honda CR-V, Changan CS75, Toyota RAV4, Volkswagen Tharu, Nissan X-Trail, Lincoln Corsair, Honda Breeze, Toyota Wildlander, Mazda CX-4, and BYD Song Pro. 3. Currently popular small SUV models include the Honda XR-V, Lynk & Co 06, Geely Binyue, Honda Vezel, Skoda Kamiq, Audi Q2L, Toyota C-HR, Volkswagen Tacqua, Tiggo 5x, and Baojun 510.

Will the car battery run out of power if the car is not driven for a long time?

If the car is not driven for a long time, the car battery will be completely depleted and eventually reach zero. Most car batteries are starting-type lead-acid batteries, which experience self-discharge over time. If left unused for an extended period, the internal power will be entirely depleted. To prevent battery drain in long-term parked cars, it is best for the owner to start the car regularly, allowing the car's built-in generator to charge the battery and ensure its normal operation. During regular car use, the following precautions should be noted: Do not overuse the battery; frequently clean the positive and negative terminals of the battery; regularly check the vent holes on non-maintenance-free battery caps to avoid blockages that could affect normal operation; turn off the auto start-stop function when shutting down the car, as auto start-stop requires frequent engine starts, which draw extremely high current and can easily lead to battery drain; avoid using high-power electrical devices as much as possible, as they frequently consume the car battery's power, significantly reducing its lifespan.

Where to Obtain the Vehicle Inspection Sticker?

Vehicle inspection stickers can be obtained at local vehicle management offices. Below are the specific steps to obtain one: 1. First, clear all traffic violations. If there are no disputes about the violations, you can pay the fines using Industrial and Commercial Bank of China's payment machines or at traffic enforcement stations (some stations may only accept cash); 2. Bring your ID card, vehicle license, compulsory traffic accident liability insurance (retained copy by traffic authorities), and proof of vehicle and vessel tax payment or exemption. Drive or take public transportation to the vehicle management office, branch office, station, or enforcement station of the traffic authorities to apply for the sticker (the vehicle itself does not need to be present); 3. Fill out the 'Motor Vehicle Inspection Sticker Application Form' on-site, then submit all documents and the form to the corresponding service window. The process typically takes about one minute; 4. After receiving the new inspection sticker, do not forget to affix it to the upper right corner of the front windshield. According to the 'Road Traffic Safety Law,' failing to place the inspection sticker in the designated location is a traffic violation, which may result in vehicle impoundment, fines, and penalty points.

What does China National V and VI mean for vehicles?

China National V and VI represent the emission standards for vehicle exhaust. Below is an introduction to National V and VI: 1. National V refers to the fifth stage of motor vehicle pollutant emission standards, with its emission control level equivalent to the Euro 5 emission standard currently implemented in Europe. 2. National VI refers to the sixth stage of motor vehicle pollutant emission standards. Below is additional information about National V and VI: 1. After a vehicle starts, the tailpipe emits harmful gases such as carbon monoxide, soot, and PM. Changing the vehicle's emission standards is aimed at effectively reducing the pollution of these wastes to the atmosphere. 2. The National VI standard is stricter than National V. 3. Registered National V emission vehicles must meet local emission standards and pass vehicle inspection before they can be driven.
