DSG gear display and wrench light flashing together indicate a problem with the hydraulic pump inside the transmission's mechatronic unit, which requires replacement. Here is relevant information: 1. The hydraulic pump is the power component of the hydraulic system, driven by the engine or motor. It draws oil from the hydraulic tank to create pressure and discharge oil, serving as a hydraulic component that provides pressurized fluid for hydraulic transmission. 2. Structurally, hydraulic pumps can be categorized into gear pumps, plunger pumps, vane pumps, and screw pumps. They convert mechanical energy from the motor into fluid pressure energy. Many factors affect the service life of a hydraulic pump, including its own design, related components, and the vehicle's operating conditions. The working principle of a hydraulic pump involves changes in the sealed volume of the pump chamber, which compresses the fluid and gives it pressure energy.

What Causes EPB Failure?

EPB failure may be caused by the following reasons: 1. Electronic parking brake malfunction; 2. Brake pad wear; 3. Electronic system failure; 4. Insufficient battery power supply. Solutions for EPB failure are as follows: 1. Reset the electronic parking brake: Turn on the car key, press the foot brake, hold the electronic parking brake down for 5 seconds, then pull it up for 5 seconds to complete the reset. 2. Use the parking brake: The parking brake can be used to stabilize the vehicle after it comes to a stop, preventing accidents caused by rolling on slopes. It usually refers to the manually operated brake installed in motor vehicles, commonly known as the handbrake. The typical handbrake is located within easy reach of the driver's right hand for convenient use. 3. Use the foot brake: Some automatic transmission models feature a foot brake with the same function as the handbrake, designed on the outer side of the driver's left foot to help drivers quickly respond to braking needs during EPB failure.

What are the left-side parking techniques?

Left-side parking techniques: 1. How to position for left-side parking: Observe the position of the left rearview mirror relative to the parking line. Turn the steering wheel fully to the left when there is still some distance between the left rearview mirror and the parking line. Shorter individuals should initiate the turn a bit earlier, while taller individuals can wait until the rearview mirror reaches the parking line before turning fully. 2. Monitor the position of the car body relative to the left corner of the parking space through the left rearview mirror: Predict whether the car body will cross the line. If maintaining the current steering angle would result in the tire being too close to the corner, then turn the steering wheel back halfway to widen the distance between the car body and the corner. Once the distance is widened, turn the steering wheel fully to the left again. 3. After the vehicle enters the parking space, observe the right rearview mirror: Straighten the steering wheel when the car body is about to become parallel. Because the car is still moving backward while straightening the steering wheel, if you straighten the wheel when the car is already parallel, it may cause the car body to become misaligned. 4. When the left rearview mirror covers the side line: You can stop the car. Shorter individuals can stop as soon as the rearview mirror touches the side line.

Is 6 Points Deduction on an A2 Driver's License Serious?

a2 driver's license deduction of 6 points is not serious. Within 30 days after the end of the current scoring cycle, you need to complete the review education at the vehicle management office. You can either attend the learning session in person at the vehicle management office or complete it online. However, online processing is only available for deductions ranging from 1 to 8 points. If you have 9 to 11 points deducted, you must attend the review in person at the vehicle management office. If an A2 license holder has 12 points deducted, they are required to attend a learning session and take an exam at the vehicle management office within 15 days of the deduction. The driving qualification can only be restored after passing the exam. Below are the relevant matters concerning the annual review and point clearance: 1. Traffic safety knowledge learning: Participate in at least three hours of learning on road traffic safety laws and regulations, civilized driving, emergency response, and other related knowledge. 2. Traffic accident case warning education: It is necessary to understand that traffic participants and road transport practitioners must consciously abide by the law and jointly maintain road traffic safety. Holders of an A2 driver's license must undergo the review within 30 days after the end of the scoring cycle. If there are no violations, the vehicle management office system will automatically approve the review and complete the annual inspection.

What does ABS braking mean?

The full name of automotive ABS is Anti-lock Braking System. Its function is to automatically control the braking force of the brake during vehicle braking, preventing the wheels from locking up and maintaining a state of rolling while sliding (with a slip ratio of about 20%), ensuring that the adhesion between the wheels and the ground remains at its maximum. Classification of ABS: ABS is mainly classified based on channels. In ABS, the brake pipelines that can independently adjust braking pressure are called control channels. ABS systems are divided into four-channel, three-channel, two-channel, and one-channel configurations. One-channel ABS: Also known as single-channel ABS, it features a single brake pressure modulator in the rear wheel brake line and a wheel speed sensor installed on the rear axle differential (sometimes one on each rear wheel). Two-channel ABS: This type of ABS struggles to balance directional stability, steering control, and braking efficiency, and is rarely used today. Three-channel ABS: It independently controls the two front wheels, while the two rear wheels are controlled together based on the low-select principle (i.e., both wheels are controlled by one channel to ensure the wheel with less adhesion does not lock up), also known as hybrid control. Four-channel ABS: Equipped with four wheel speed sensors, it includes a brake pressure modulator in the pipeline to each wheel's brake cylinder for independent control, forming a four-channel control system.

What does ECU mean and what are its functions?

ECU in automobiles refers to the onboard computer. ECU (Electronic-Control-Unit), also known as "vehicle computer" or "onboard computer". In terms of its purpose, it is a specialized microcomputer controller for automobiles. Like a regular computer, it consists of a microprocessor (MCU), memory (ROM, RAM), input/output interfaces (I/O), analog-to-digital converters (A/D), as well as shaping, driving, and other large-scale integrated circuits. Here are some common causes of ECU damage: 1. During welding repairs on the vehicle frame, the ECU wire connections were not disconnected. During welding repairs on the frame, changes in current can generate extremely high induced electromotive force, which can harm the ECU through the wiring. 2. When the battery is low, using a direct silicon-controlled rectifier (SCR) charger to charge it. The high-order harmonics produced by the SCR circuit can damage the ECU. 3. Alternatively, if the charger voltage is too high, the polarity is reversed, or the ignition switch is turned on or even the generator is started while charging. 4. If maintenance personnel disassemble the ECU without caution, touch the electronic control unit interfaces with their hands, or use a soldering iron without grounding function to solder the CMOS chip of the ECU, it can cause the CMOS chip to be damaged by static electricity. 5. If the positive and negative terminals of the battery are suddenly disconnected while the engine is running, the circuit can generate a very high induced electromotive force, which may cause the internal electronic components of the ECU to be damaged.
