BMW differential oil is generally changed every 3 years. These maintenance tasks need to be performed on schedule to ensure stable, comfortable, and safe driving. Below are the relevant details: 1. The function of differential oil: There is a differential in the rear wheels of a vehicle, and this oil serves as a lubricant. It lubricates and protects the differential. The differential is used to balance the speed difference when turning. 2. Changes in the center of gravity: Because the vehicle's center of gravity changes when turning, this mechanism is very important. Simply put, the differential lock helps the wheels overcome resistance. For example, if two wheels get stuck, the other two can still pull them out normally.

Can You Cross the Dotted Line During Parallel Parking?

Parallel parking should not involve crossing the dotted line. Here are some additional details: 1. Key points for parallel parking: The parking space boundaries are now marked solely by ground lines instead of poles. For those obtaining a C1 driver's license, the length of the parallel parking space is 1.5 times the vehicle length plus 1 meter. Drive the vehicle parallel to the parking space, then reverse into the space without any pauses. As long as the vehicle is parked within the boundary lines, it is considered a pass. 2. Grading criteria: If the vehicle body crosses the line after stopping, 100 points are deducted. If the wheels touch the lane boundary lines during movement, 10 points are deducted. Failure to park within the space results in a 100-point deduction. Not using the left turn signal when starting incurs a 10-point deduction. Pausing during the maneuver leads to a 100-point deduction. The new regulation's challenge: No poles for reference and no pauses allowed.

What does the SVS light in a diesel vehicle mean?

Diesel vehicle SVS light is an engine fault indicator light. Here is the extended information: 1. Diesel vehicle SVS light: After starting the engine, when the engine ECU detects a fault in the engine, the SVS light will illuminate, indicating that there is a fault in the vehicle's engine. For such engine faults, it is recommended to seek professional mechanics for handling and inspection, first checking whether it is a sensor or wiring fault. If it is an engine fault, it should be addressed promptly. 2. Solution for diesel engine SVS light illumination: You can try to start the engine. If it cannot start, it may be due to an abnormal fuel pump, which needs to be replaced. If it can still start, it could be a fault with other sensors. In this case, the vehicle can still be driven, but the fault may affect the normal use of the vehicle, so it is recommended to go to a repair shop for inspection as soon as possible.

Which Side is the Turn Signal On?

On the left side of the steering wheel, pushing down activates the left turn signal, while pushing up activates the right turn signal. Here is some related information: 1. Warning Light: The turn signal is a warning light that alerts surrounding vehicles and pedestrians to yield when a motor vehicle is turning. When the turn signal is activated, the light flashes repeatedly to attract attention and prevent traffic accidents. Drivers must develop the habit of using turn signals when driving on the road and avoid driving blindly. 2. Function: However, with advancements in automotive technology, many cars now feature a 'one-touch three-flash' quick function on the hazard light switch. By lightly 'tapping' the lever, the turn signal will flash three times and then automatically turn off. This allows drivers to avoid the hassle of manually turning off the turn signal when changing lanes or overtaking.

What are the disadvantages of buying a stock car?

Buying a stock car has disadvantages such as electronic component failures and oil oxidation. Here are some details about the disadvantages of buying a stock car: 1. Electronic component failures: When a vehicle is parked in one place for a long time, the electronic components may become damp due to lack of power. Dampness can lead to oxidation and corrosion, making it easy for these components to malfunction when they are eventually used. The longer the vehicle remains idle, the greater the impact on its electronic components. 2. Oil oxidation: Engine oil, brake fluid, and other fluids deteriorate over time. Even after three months, the engine oil should be replaced. Once oil is used, it begins to oxidize due to exposure to air, significantly reducing its performance.

What does a mortgaged car mean?

A mortgaged car refers to the property provided by the car owner as collateral to financial institutions for raising funds through loans. If the car owner fails to fulfill the debt, the financial institution has the right to auction or sell the property at a discounted price in accordance with the law, with priority given to repayment from the proceeds. A non-full payment mortgaged car means the vehicle is still under mortgage status with the vehicle management office and the bank. Risks of mortgaged cars: Many mortgaged car trading platforms cannot guarantee the legitimacy of the vehicle's source. If the mortgaged car comes from an illegitimate source or is a stolen vehicle, significant troubles may arise later, including vehicle confiscation and potential criminal liabilities. Categories of mortgaged cars: Purchasing a car through mortgage loans. In this case, the lender is usually designated by the 4S store, including bank loans and auto financial loans. Bank loans involve the bank as the lender, with the vehicle mortgaged to the bank; auto finance typically refers to the car manufacturer's own financial company, with the vehicle mortgaged to the manufacturer. Documents required for purchasing a mortgaged car: The original or color copy of the vehicle pledge loan agreement signed by the car owner, the vehicle registration certificate, a copy of the car owner's ID card, and the vehicle transfer agreement. The more complete the remaining debt agreements and vehicle-related documents are, the better, as these documents are fundamental for protecting one's rights in the future.
