BMW transmission fluid needs to be changed. Here is the relevant information: Specific reasons: Because the transmission relies on transmission fluid for heat dissipation, lubrication, and hydraulic power transmission, prolonged use of transmission fluid will definitely significantly reduce the performance of the transmission. When the transmission fluid is severely contaminated, it can also lead to a series of transmission problems. The role of BMW transmission fluid: Under normal driving conditions, the temperature of the transmission fluid is usually below 135°C. However, when the vehicle is overused, such as when towing overloaded trailers, or when driving in four-wheel-drive mode set for snow or off-road conditions, the vehicle may experience excessive torque converter slippage, which can cause the transmission fluid temperature to reach 135°C.

Can I wear a skirt for the Subject 2 driving test?

Generally, it is not recommended to wear a long skirt while practicing driving, as it may easily get tangled with the clutch or brake pedals, posing safety hazards. Below are precautions for the Subject 2 test: 1. Reverse parking into a garage: (1) Ensure accurate alignment with reference points and lines, observing the distance between the car body and lines via rearview mirrors to avoid crossing boundaries. (2) Do not stop until the vehicle is fully inside the garage; control the clutch properly to prevent midway stops or incomplete parking. After entering the area, park at the designated spot, then reverse into the garage; exit towards another direction and repeat the process; finally exit towards the test area to complete the exam. 2. Parallel parking: (1) Maintain proper side distance when aligning with the garage to avoid crossing lines, and watch for not hitting garage corners when exiting. (2) Remember to activate turn signals when exiting. After entering the area, align parallel to the garage, drive to its front-left side, reverse into the garage from the right rear, then exit to finish the test.

What to Do When the Car Makes a Crisp Metal Clanking Sound?

The solutions for a car making a crisp metal clanking sound are as follows: 1. Locate the source of the sound: First, identify what kind of abnormal noise it is. If it's a noise from the car body, certain parts may produce sounds when accelerating or braking. If the noise is not loud and doesn't affect normal driving. 2. Determine the cause of the noise: This issue usually arises due to insufficient body rigidity, causing deformation during driving, friction or shaking between doors and frames, or friction between steel plates due to welding failures. 3. Address the noise based on specific circumstances: If the noise is caused by friction around the doors or windows, applying adhesive strips or padding rubber in the friction areas might reduce or eliminate the noise. If none of the above issues are found, it's essential to take the car to a professional repair shop for a thorough inspection and problem diagnosis.

What are the reasons why the ignition coil of Toyota Corolla is prone to burn out?

Toyota Corolla ignition coil is prone to burn out for the following reasons: 1. Design and manufacturing issues with batch spare parts, leading to ignition coil damage; 2. The thermal effect of current damages the coil insulation inside the ignition coil; 3. Engine overheating, causing the coil insulation varnish to melt and fail; 4. Excessive spark plug electrode gap, increasing the load on the ignition coil and causing the high-voltage coil to break down, resulting in short circuits or open circuits; 5. High-voltage line open circuit, making the generated high-voltage electricity unable to pass through, easily causing the high-voltage coil to break down.
