What Causes the Brake Caliper to Make Abnormal Noises?

Can I change the test center if I fail the Subject 3 driving test?

You cannot change the test center if you fail the Subject 3 driving test, as the test center for the driver's license examination is determined by the driving school and vehicle management office according to regulations, and examinees are not allowed to switch test centers. Subject 3 includes the road driving skills test and the safety and civilized driving knowledge test. It is part of the motor vehicle driver's license assessment and is the abbreviation for the road driving skills and safety and civilized driving knowledge test in the motor vehicle driver's examination. The content of the road driving skills test varies for different types of vehicles. Subject 3 Road Driving Skills Test Content: Preparation before getting on the vehicle, simulated light test, starting, driving straight, shifting gears, changing lanes, pulling over, driving straight through intersections, turning left at intersections, turning right at intersections, passing pedestrian crossings, passing school zones, passing bus stops, meeting vehicles, overtaking, making U-turns, and nighttime driving. Subject 3 Safety and Civilized Driving Knowledge Test Content: Requirements for safe and civilized driving operations, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations such as tire blowouts, and post-accident handling knowledge. Notes for the Subject 3 Test: 1. If the examinee's fingerprint verification fails, they must get off the vehicle to re-collect their fingerprint before queuing again for the test. 2. During the test, if the examinee's score falls below the passing score, the system will automatically prompt the examinee to pull over. After completing the pull-over action, the system will prompt the examinee to proceed to the next test. 3. After the examinee completes all required test items and drives a distance of more than 3 kilometers, the system will automatically prompt them to pull over. Upon hearing the pull-over prompt, the examinee should choose a clear curb (or solid road edge) on the test route and complete the pull-over action after confirming safety. The system will then announce the test results. 4. When walking around the vehicle to inspect its appearance and surroundings, ensure the accuracy of radar signal detection by keeping a distance of within 1 meter between the body and the vehicle. 5. If multiple examinees are preparing for the test simultaneously, after one examinee finishes the test, the next examinee must follow the standard procedure, including getting off the vehicle, preparing to get on, walking around the vehicle, and starting with the simulated nighttime light test.

What does it mean when the ABS light appears on the car's dashboard?

When the ABS light appears on the car's dashboard, it indicates a malfunction in the vehicle's Anti-lock Braking System. During emergency braking, if the wheels lock up, the vehicle may lose control and skid, making it difficult for the driver to slow down or adjust the vehicle's trajectory, which poses a significant safety hazard. There are several states in which the ABS light may illuminate, each with different causes and solutions. The details are as follows: State 1: ABS warning light stays on continuously (most common). Cause 1: The ABS speed sensor's sensing area is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. As a result, the ABS computer cannot determine the vehicle's speed or the wheel's slip rate, and thus cannot issue the appropriate commands to adjust braking. Solution: Clean the dirt from the speed sensor and adjust the gap between the speed sensor and the signal ring to restore normal function. Cause 2: Poor signal transmission due to loose system wiring connections or poor contact in the ABS relay, leading to system failure. Solution: Check the wiring connections and reconnect any loose parts. State 2: ABS warning light intermittently illuminates but turns off when accelerating. Cause: When multiple vehicle electrical devices are in use, the battery voltage drops below 10.5V. As the engine speed increases, the voltage rises, and the ABS warning light turns off. This may also occur if the ABS system's power supply voltage is too low, such as due to poor terminal contact or grounding issues. Solution: Check the battery's specific gravity, inspect the charging system, and examine the power supply (e.g., voltage relay or poor power contact). State 3: ABS warning light stays on after the engine starts and only turns off when the engine is turned off (IGFF). Cause: Poor grounding contact in the ABS hydraulic valve body; poor contact in the ABS hydraulic valve body's wiring connector; ABS computer malfunction. Solution: Loosen the grounding screw on the hydraulic valve body, then retighten it. Clean the contact surface if necessary. Check if the connector gap has widened. Replace the ABS or ABS/ASR computer if needed. State 4: ABS warning light illuminates during high-speed driving. Cause: At high speeds, the ABS computer detects a significant discrepancy between the rear and front wheel speed signals. This may also occur if the tire or wheel rim specifications are incorrect. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the label near the fuel tank cap. State 5: ABS warning light intermittently illuminates. Cause: Improper adjustment of the brake light switch; poor internal contact in the brake light. Solution: Start the engine, press the brake pedal, and use a finger to push the brake switch linkage all the way down. Then release the brake pedal to complete the self-setting position. Replace the brake light switch if necessary.

What is the fuel consumption per 100 kilometers for the Volkswagen Tiguan 1.8t?

The Volkswagen Tiguan 1.8t has a total of 8 models, with official fuel consumption data ranging from 7.9 to 8.9 liters per 100 kilometers. Among them, the Tiguan-2015-1.8TSI-Automatic Four-Wheel Drive Luxury, Comfort, and Fashion Vision models are equipped with a 160-horsepower engine, with an NEDC fuel consumption of 8.9 liters per 100 kilometers. The Tiguan-2015-1.8TSI-Automatic Two-Wheel Drive Luxury, Comfort, and Fashion models, also equipped with a 160-horsepower engine, have an NEDC fuel consumption of 8.6 liters per 100 kilometers. The Tiguan-2015-1.8TSI-Manual Two-Wheel Drive Limited Edition and Fashion models, also with a 160-horsepower engine, have an NEDC fuel consumption of 7.9 liters per 100 kilometers. The fuel grade for the Volkswagen Tiguan 1.8t is 95, with an average fuel price of 8.56 yuan per liter. The fuel cost per 100 kilometers for different models is as follows: 2015-1.8TSI-Automatic Four-Wheel Drive Luxury, Comfort, and Fashion Vision models, the fuel cost per 100 kilometers is 8.9*8.56=76.184 yuan. 2015-1.8TSI-Automatic Two-Wheel Drive Luxury, Comfort, and Fashion models, the fuel cost per 100 kilometers is 8.6*8.56=73.616 yuan. 2015-1.8TSI-Manual Two-Wheel Drive Limited Edition and Fashion models, the fuel cost per 100 kilometers is 7.9*8.56=67.624 yuan. The fuel tank capacity for all Volkswagen Tiguan 1.8t models is the same, at 63 liters. The distance that can be covered on a full tank of fuel is as follows: 2015-1.8TSI-Automatic Four-Wheel Drive Luxury, Comfort, and Fashion Vision models, the distance on a full tank is 63/8.9*100=707 kilometers. 2015-1.8TSI-Automatic Two-Wheel Drive Luxury, Comfort, and Fashion models, the distance on a full tank is 63/8.6*100=732 kilometers. 2015-1.8TSI-Manual Two-Wheel Drive Limited Edition and Fashion models, the distance on a full tank is 63/7.9*100=797 kilometers. The fuel consumption of a car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. Specific factors that can increase fuel consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not easing off the throttle before a red light, can increase fuel consumption. The car itself: Cars with larger engine displacements generally consume more fuel than those with smaller displacements because larger displacements usually mean higher power, requiring more gasoline to burn and perform work. Heavier cars also consume more fuel because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases the car's resistance and fuel consumption. Low environmental temperatures: When the engine block is cold, the injected gasoline does not atomize easily, requiring more gasoline to burn, which increases fuel consumption. Additionally, at low temperatures, the engine's computer may control the engine to run at higher RPMs to warm up, further increasing fuel consumption.

Can Temporary License Plates Be Issued on Saturdays and Sundays?

For the Geely Xingyue models equipped with the JLH-4G20TDB turbocharged engine, it is recommended to use 95-octane gasoline; for models with the JLH-3G15TD engine, 92-octane gasoline is recommended, as specified in the vehicle's official user manual. In addition to checking the suitable gasoline grade in the user manual, Geely Xingyue owners can also find this information on the fuel tank cap, where the recommended gasoline grade is usually indicated. Generally, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92-octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95-octane gasoline. If the compression ratio is even higher, 98-octane gasoline is recommended. However, with the application of new technologies, the compression ratio alone cannot determine the appropriate gasoline grade, as high-compression engines can sometimes be tuned to use lower-octane gasoline. This is because other factors, such as ignition timing, turbocharging technology, and Atkinson cycle technology, also play a role. Generally, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. If a Geely Xingyue owner occasionally uses the wrong gasoline grade, simply switching back to the correct grade after the tank is empty is sufficient. However, prolonged use of the wrong gasoline grade can have the following effects: For vehicles designed for lower-octane gasoline, using a higher-octane grade will not cause damage, but the increased octane number can alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. For vehicles designed for higher-octane gasoline, using a lower-octane grade can cause engine knocking. The significantly lower octane number lowers the fuel's ignition point, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, it creates resistance during the upward stroke. This resistance makes the engine run very unevenly. If the knocking is mild, it may only increase noise without noticeable engine damage. However, severe knocking indicates serious engine issues, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, potentially leading to cylinder scoring.

Can motorcycle oil be replaced with car oil?

Motorcycle oil cannot be replaced with car oil; specialized motorcycle oil must be used. The working characteristics of motorcycle engines differ from those of car engines. Motorcycle engines operate at higher RPMs with faster acceleration, and car oil cannot meet the lubrication requirements of motorcycle engines. Engine oil is something every vehicle owner deals with, often referred to as the 'blood of the engine.' Without oil, an engine cannot function. Inside the engine, oil not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat. When the engine is running, the oil forms a protective film on the surfaces of various components, preventing direct contact and friction between them.

What Causes Engine Stall During U-Turns?

Engine stall during U-turns can be attributed to several reasons: 1. Throttle: Sticking or deformation due to external forces may cause stalling. 2. Motor: Open circuits, short circuits, or erosion/aging can lead to low-speed stalling. 3. Fuel system: Insufficient fuel pressure or fuel pump malfunction may result in stalling. 4. Fuel injector: Clogged injectors causing poor fuel atomization can make the engine operate abnormally and potentially stall. 5. Igniter erosion: With ignition voltage reaching tens of thousands of volts, accumulated oil at the ignition coil terminal may cause erosion, leading to abnormal ignition and easy stalling.
