Has the Volkswagen Tiguan L Particulate Filter Issue Been Resolved?

Volkswagen Tiguan L particulate filter issue has been resolved, and the official recommendation is to frequently drive on highways. Below is the relevant introduction: Regeneration function: It can effectively reduce particulate matter emissions by first capturing particulate matter in the exhaust gas and then oxidizing the captured particles, regenerating the particulate filter, which can reduce soot produced by diesel engines by more than 90%. The captured particulate emissions are subsequently burned off during vehicle operation. Purification function: After the purification cycle is completed, any residual dust or filter residue will ultimately be manually removed during routine maintenance. With the assistance of the engine control system, it not only controls the quantity of particulate emissions but also regulates the emissions of pollutants such as hydrocarbons and polluting gases.

The Full Name of AMG

AMG stands for Aufrecht-Melcher-Grossaspach. Currently, it is the official tuning company for Mercedes-Benz. Here are some related introductions: More outstanding: Mercedes-Benz vehicles modified by AMG are more outstanding in terms of both performance and appearance, and they frequently dominate on the racetrack. Therefore, Mercedes-Benz models with the AMG logo are high-performance versions. Initially, AMG focused on modifying and upgrading engines for various car brands. It wasn't until 1978 that AMG was acquired by Mercedes-Benz and became a subsidiary. Exclusive cooperation: After establishing an exclusive cooperation with AMG, Mercedes-Benz flourished, achieving numerous excellent results in competitions such as the German Touring Car Championship. In 1990, AMG, which had gained significant fame in racing, established a second factory and began modifying and selling Mercedes-Benz production vehicles.

Why Does the Car Make Noise When Braking Cold?

Car cold braking noise may be caused by the brake vacuum booster, which is a common phenomenon in most vehicles and does not affect driving safety. If the noise is too loud, the brake vacuum booster can be replaced. The working principle of the brake vacuum booster is as follows: 1. Start the engine. When the engine is in the intake stroke, the vacuum degree in the intake manifold is greater than that in the rear chamber of the vacuum booster, and the vacuum damping valve opens at this time. 2. The engine draws air from the rear chamber through the intake manifold into the engine via the vacuum damping valve. When the vacuum degree in the rear chamber exceeds that in the intake manifold, the vacuum damping valve closes, creating a vacuum and negative pressure in the rear chamber. 3. When the brake pedal is pressed, the one-way valve inside the vacuum booster closes, and the pressure relief valve opens, allowing air to enter the front chamber of the vacuum booster through the pressure relief valve, creating positive pressure. Since the pressure in the front chamber is greater than that in the rear chamber, a pressure difference is generated. 4. Under the positive pressure in the front chamber, the diaphragm is pushed toward the rear chamber, overcoming the return spring force of the pressure plate, and the push rod of the brake master cylinder is pushed, driving the first-stage piston of the brake master cylinder to generate vacuum assistance.

Precautions for Vehicle Maintenance in Autumn

Precautions for autumn car maintenance include the following aspects: 1. Engine compartment maintenance: Check the engine oil, brake fluid, and antifreeze in the engine compartment to see if the fluids are sufficient, deteriorated, or have reached the replacement cycle. These fluids are like the blood of the car. When they reach the replacement cycle, they must be replaced to ensure smooth fluid circulation. 2. Brake system maintenance: Regularly check if the braking system has weakened or is pulling to one side, and if there are any changes in the pedal force. If necessary, clean the entire brake system's pipeline. 3. Heater lines and fan maintenance: As the weather turns cooler in autumn, frost may appear when temperatures drop. Pay special attention to whether the defroster vents under the windshield are functioning normally and if the heat is sufficient. Address any issues promptly. 4. Air conditioning maintenance: After a summer of use, the car's air conditioning system needs a thorough inspection to ensure it provides adequate heating in winter. Check if the pipelines are intact and if the air filter needs replacement. 5. Battery maintenance: In autumn, the electrode terminals of the car battery are most prone to problems. During inspection, if green oxides are found at the terminals, rinse them off with boiling water. These oxides can cause insufficient generator power, leading to a discharged battery. In severe cases, it may result in battery failure or difficulty starting the car. 6. Interior maintenance: Due to the high temperatures and frequent rain in summer, the car's carpets, floor mats, and other hidden areas may harbor bacteria. Therefore, it is essential to perform a thorough interior disinfection and cleaning of the car.

What are the wheel hub damage assessment criteria?

Auto damage insurance coverage does not include tires. Below is the relevant information: Auto Damage Insurance: It is a primary coverage under motor vehicle damage insurance. The definition of primary coverage refers to losses incurred by the entire vehicle in traffic accidents, which are covered under insurance liability, and the insurer compensates according to the insurance policy terms. Consumables: Since vehicle tires are consumables, they are naturally not covered under auto damage insurance. This exclusion means that when tires are damaged independently, such as a flat tire or when the outer tire wears to a certain extent; however, if tires are damaged during a traffic accident, the tire damage is within the insurance coverage.

Should You Use High Beams or Low Beams on the Highway at Night?

On the highway, use high beams, but switch to low beams when the distance to the vehicle in front is within 100 meters. Highway lighting selection: In normal weather conditions, fog lights should not be turned on, whether during the day or at night. Additionally, when meeting oncoming traffic on roads without a median, you should slow down at a distance of about 150 meters and switch from high beams to low beams. If the oncoming vehicle does not switch to low beams, the driver should slow down and use the method of alternating between high and low beams to signal the oncoming driver. If the oncoming driver still does not switch their lights, simply continue driving in your own lane. How to use the lights: To operate the lights, first ensure the vehicle is in the ignition-on state. The headlights, width lights, and other lights are controlled by the lighting control knob (or button) on the left side of the driver's seat. The turn signals are controlled by the lighting control lever on the left side of the steering wheel.
