What Causes Gear Shift Jerkiness in Automatic Transmission Vehicles?

What are the symptoms of a dirty car throttle?

Symptoms of a dirty car throttle: 1. When accelerating, you may feel the throttle sticking, becoming heavy, with slow vehicle acceleration. The engine RPM rises slowly when pressing the throttle at idle, showing delayed response. When releasing the throttle while driving, the vehicle speed drops immediately; 2. It affects the precision and smoothness of engine air intake. A noticeable issue is that it may cause shaking or even stalling at idle, as well as unsmooth acceleration when pressing the throttle. Reasons for a dirty throttle: 1. Driving environment, poor air filter performance, or high dust levels in the surrounding environment; 2. Low-quality engine oil with high evaporation rate; 3. Generated by oil vapor and impurities in the crankcase; 4. After turning off the engine, the throttle cannot seal completely, allowing some dust to be sucked in.

How to Bleed Air After Changing Brake Fluid?

Methods for bleeding air after changing brake fluid: 1. Connect a bottle filled with water to the bleeder valve using a hose. One person presses the brake pedal inside the car while another observes if the dirty fluid has been completely drained. Add new brake fluid and continue pressing the brake pedal until clear new fluid comes out of the bleeder valve and no bubbles are seen in the water bottle. 2. Use a vacuum fluid extractor to suck the old brake fluid out from the bleeder valve. After adding new brake fluid, continue extracting until the discharged fluid is clear and free of air. Situations requiring brake fluid replacement include: 1. When brake fluid absorbs moisture or contains impurities; 2. When the vehicle experiences inconsistent braking performance during normal driving, the brake fluid should be replaced promptly; 3. When the wheel cylinder rubber cup expands excessively; 4. Brake fluid should be replaced every two years.

How to Replace the Brake Light of a 2015 Lavida?

2015 Lavida brake light replacement method: First open the rear trunk, there is a white screw on the reverse side of the taillight, unscrew the screw and remove the plug, then take out the old brake light and replace it with a new one. The brake light is installed at the rear of the vehicle and is red in color to enhance the penetration of the light source, making it easier for vehicles behind to detect the braking of the vehicle in front even under low visibility conditions, thereby preventing rear-end collisions. The 2015 Lavida is an independently developed A-segment car launched by Shanghai Volkswagen, with a body length, width, and height of 4605mm, 1765mm, and 1460mm respectively, and a wheelbase of 2610mm. In terms of appearance, the front face design of the 2015 Lavida is significantly different from previous A-segment models under Volkswagen, especially its unique teardrop-shaped headlight design.

Is it necessary to complete all theoretical training?

The necessity of completing all theoretical training mainly depends on how the driving school sets the training hours. If the training hours are determined based on theoretical training, then you need to watch a portion of the videos, but generally, it is not required to watch all of them. The review process for the subject one videos takes 3-7 working days. Once approved, you will receive the corresponding training hours. As long as the total training hours meet the requirements, you can schedule the exam. Additional information: 1. Required training hours: According to relevant regulations, the theoretical training hours for subject one must reach 18 hours, with practical training hours at 6 hours; subject two requires 2 hours of theoretical training and 22 hours of practical training; subject three requires 10 hours of theoretical training and 28 hours of practical training, totaling 86 hours. 2. Theoretical training: This refers to training in safety skills and other aspects, and you must complete the required hours before taking the exam. For driver theoretical training, you generally need to bring training materials, follow the instructor's guidance, take notes on key knowledge points and exam requirements, etc. Driving schools usually organize students to take mock exams in electronic classrooms. After passing, you can proceed to the theoretical exam administered by the examination department.

What Are the Classification Standards for Vehicle Wheelbase Levels?

Vehicle grades are generally divided into six levels: A00, A0, A, B, C, and D. According to the German vehicle classification standards, A-class vehicles refer to small passenger cars; B-class vehicles are mid-range passenger cars; C-class vehicles are high-end passenger cars; and D-class vehicles are luxury passenger cars. The classification is mainly based on parameters such as wheelbase, engine displacement, and weight. The further the letter is in the alphabet, the longer the wheelbase, the larger the displacement and weight, and the higher the level of luxury of the passenger car. Passenger cars are categorized as A00 (micro cars), A0 (subcompact cars), A (compact cars), B (mid-size cars), C (full-size cars), and D (luxury cars). 1. Based on vehicle length: under 3.7M for micro cars (e.g., QQ), 3.7-4.3M for subcompact cars (e.g., 206), 4.3-4.6M for compact cars (e.g., Sagitar), 4.6-4.9M for mid-size cars (e.g., Camry), 4.9-5.1M for full-size cars (e.g., A6L), and over 5.1M for luxury cars (e.g., Mercedes-Benz S-Class). 2. Based on wheelbase: under 2350mm for micro cars, 2350mm-2500mm for subcompact cars, 2500mm-2700mm for compact cars, 2700mm-2800mm for mid-size cars, 2800mm-2900mm for full-size cars, and over 2900mm for large luxury cars.

Is the fuel tank cap of a Mercedes-Benz on the left or right side?

On the right side. The fuel tank cap switch of a Mercedes-Benz is generally linked to the car door. When the door is opened, the fuel tank cap automatically unlocks, and pressing the fuel tank cap switch will pop it open. Below are specific details on cleaning the fuel tank: Regular Cleaning: A sealed fuel tank can accumulate a lot of gum, sludge, particulate matter, and foil. Many substances in the fuel require regular cleaning to prevent excessive impurities from causing malfunctions. Effects of Long-Term Neglect: Excessive deposits of impurities and water at the bottom of the fuel tank can clog the ventilation pipes and fuel lines, creating negative pressure inside the tank. This leads to poor fuel supply, sluggish throttle response, and reduced vehicle performance. If the fuel level is too low or insufficient at this time, it is essential to refuel immediately—do not wait until the warning light comes on. If the fuel pump continues to operate under these conditions, it may overheat, affecting its lifespan, and in severe cases, could even cause the pump to burn out.
