What Causes the Steering Gear of BMW to Make Abnormal Noises?

Should Brake Fluid Be Replaced?

Yes, it should be replaced. Changing the brake fluid in a car ensures optimal braking performance. Below are the reasons for unusual noises when braking: 1. "Hissing" sound: This indicates a fault in the caliper, brake pad, or brake shoe. 2. Continuous noise: This is caused by poor caliper retraction, leading to prolonged friction between the disc and pad. 3. Foreign objects: There may be debris between the brake pad and brake disc. 4. Faulty guide pin: The brake guide pin is malfunctioning. Below are the reasons for steering wheel vibration during braking: 1. Wear: Uneven wear on the brake disc can cause steering wheel vibration when braking at high speeds. 2. Braking imbalance: When driving at a certain speed, uneven braking torque can cause the left and right wheels on the same axle to desynchronize, resulting in brake looseness. 3. Uneven rolling speed: If the braking torque imbalance becomes severe, it can cause the left and right wheels to roll at different speeds, leading to side-to-side wheel oscillation, which is then transmitted to the steering wheel.

What are the consequences of not repairing a slipping clutch?

Consequences of not repairing a slipping clutch: A slipping clutch in a car can easily lead to insufficient driving power, posing safety hazards; the car is highly prone to oil leakage when climbing slopes, potentially causing accidents; prolonged clutch slipping can also severely damage car components, such as the clutch and flywheel. Causes of clutch slipping: Excessive wear of the driven disc friction plate or exposed rivets; the clutch pressure plate spring is too soft or broken; the clutch pedal free travel is too small; oil contamination or aging hardening on the driven disc friction plate; loose bolts connecting the clutch to the flywheel; blocked return oil hole in the clutch master cylinder. Clutch troubleshooting methods: Check the pedal free travel. If the free travel is normal, remove the clutch bottom cover and check whether the bolts connecting the clutch cover to the flywheel are loose. If loose, tighten them; if they do not meet the standard value, adjust them. Check if there is oil splashed from the edges of the clutch friction plate. If oil is present, remove and clean with gasoline or alkaline water, then dry; if severe wear, exposed rivets, aging hardening, burning, or oil saturation are found on the friction plate, replace it with a new one. Check the return oil hole of the clutch master cylinder, and unclog it if blocked.

What is the Function of an Electronically Controlled Automatic Transmission?

The function of an electronically controlled automatic transmission is to select the optimal gear ratio for different loads and vehicle speeds, ensuring the engine operates at a corresponding stable speed. All gear shifts are performed automatically by the transmission, with the driver only needing to use the accelerator pedal to indicate their intent for speed changes and the gear selector to choose the desired operating mode. The electronically controlled automatic transmission is developed by adding an electronic control system to the traditional hydraulic automatic transmission. Common types of automotive automatic transmissions include: hydraulic automatic transmission (AT), continuously variable transmission (CVT), automated manual transmission (AMT), and dual-clutch automatic transmission.

Which lines on the highway cannot be crossed?

Highway lines that cannot be crossed are as follows: 1. Solid white line: Solid white lines generally appear in front of traffic light intersections. Their purpose is to separate lanes in the same direction. These solid white lines cannot be crossed. Many drivers attempt forced lane changes here, which can result in fines and penalty points. 2. Single solid yellow line: These solid lines typically appear on roads with only one lane in each direction. Crossing them is prohibited, and cameras often monitor these areas. Violations will lead to fines and penalty points. 3. Double solid yellow lines: These lines usually appear on roads with two or more lanes in each direction without a central divider. They serve to separate opposing traffic flows and must not be crossed. 4. Yellow solid and broken line combination: These lines typically appear at intersections, indicating where U-turns are permitted. Remember that only the side with broken lines allows U-turns, while the solid line side prohibits them. 5. Yellow no-parking line: These solid lines appear along road edges, indicating no-parking zones. Naturally, crossing these lines is also prohibited. 6. No-parking grid lines: These grid-patterned lines mainly appear at intersections. Designed to alleviate traffic congestion, parking is strictly prohibited within these areas.

How often is the driver's license point reset?

A driver's license has a scoring cycle of 12 months with a full score of 12 points, calculated from the initial issuance date of the license. For example, if the license was issued on January 1st, then every year on this date, the points on the license will be reset. This cycle continues indefinitely. More detailed information is as follows: 1. Point Reset Method: If the penalty points accumulated during a scoring cycle do not reach 12 points, the scoring system will automatically reset the points from the previous cycle (after paying the fines) at the start of the next scoring cycle. If the points reach 12, the driver must attend a learning session and pass the subject one exam at the local vehicle management office where the license was issued or where the violation occurred (if the points reach 12 twice consecutively in one scoring cycle, the subject three exam must also be passed after upgrading the license). Only then can the points be reset. Otherwise, the driver's license cannot be used normally. 2. Legal Basis: According to Article 25 of the "Regulations for the Implementation of the Road Traffic Safety Law," if a motor vehicle driver accumulates 12 points and refuses to attend the learning session notified by the traffic management department of the public security organ or to take the exam, the traffic management department of the public security organ will announce the suspension of the driver's license.

What Causes a Car Navigation Screen to Go Black While Still Having Sound?

Reasons for a car navigation screen going black while still having sound: 1. The motherboard operating voltage is unstable, causing a crash; 2. The touch screen is damaged; 3. The decoding chip or core module is not working or is damaged; 4. The power plug of the navigation display is loose. Car navigation systems feature GPS global satellite positioning functionality. Once the destination is input into the car navigation system, the system automatically calculates the route based on the electronic map and guides the driver to follow the calculated route during the journey. The car GPS navigation system consists of two parts: one part includes the GPS receiver and display device installed in the car; the other part is the computer control center. These two parts communicate via positioning satellites.
