Driving 10-20 kilometers with a tire pressure of 1.9 bar is not a significant issue. However, excessively low tire pressure can cause severe deformation of the tire sidewall, damage the cord layer, and potentially lead to a tire blowout. Hazards of low tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Causes the steering wheel to feel heavy and may lead to vehicle drift, compromising driving safety; Increases movement in various parts of the tire, causing abnormal heating due to excessive rolling; Reduces the functionality of the cord and rubber, leading to delamination or cord breakage, excessive friction with the rim, causing damage to the bead area and abnormal wear; Doubles the friction between the tire and the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving under these conditions may result in a tire blowout; Increases tire body deformation, making the tire sidewall prone to cracking, while also causing flexing movements that lead to excessive heat, accelerating rubber aging, cord layer fatigue, and cord breakage. It also increases the tire's contact area with the ground, accelerating shoulder wear. Solutions for insufficient tire pressure: If no damage is visible, simply inflate the tire to the normal pressure and reset the tire pressure system; If a puncture is found during inspection, promptly drive to a tire shop for repair and then reinflate the tire; If the tire pressure warning reappears some time after inflation without any puncture, it may be due to air leakage caused by rim deformation. It is advisable to inspect the rim and consider replacement.

What Causes the Volkswagen Anti-Slip Light to Illuminate?

The reason why the Volkswagen Lavida's anti-slip light is on may be due to accidentally pressing the ESP off button; below are the specific reasons for the Volkswagen Lavida's anti-slip light illuminating: Other reasons: Loose or faulty sensor connectors; short circuits in the wiring or related fuse blowouts; software issues causing poor signal transmission; ABS pump failure. When the anti-slip system light is on, it indicates that the ESP is turned off or has malfunctioned. Damaged steering angle position sensor: The steering angle position sensor is located below the steering wheel and sends signals about the steering wheel's rotation to the control unit. Without the sensor's signal, the vehicle cannot determine the driving direction, causing the fault indicator light to illuminate.

What Causes Abnormal Noise in the Car Fuel Tank?

Abnormal noise in the car fuel tank may be the sound of the fuel pump working. If the noise is not the current sound of the fuel pump motor, it could indicate an abnormal fuel pump that needs replacement. Symptoms of an abnormal fuel pump include: 1. Weak vehicle acceleration, especially with noticeable hesitation during rapid acceleration. 2. Difficulty starting the vehicle, including failure to ignite or hard starting. 3. The engine fault light on the vehicle's instrument cluster remains constantly illuminated. Additional Information: As the most fundamental component in the engine fuel supply system, the fuel pump is responsible for drawing fuel from the tank during engine operation and delivering it continuously through the fuel supply line to the engine at a certain pressure. The high-pressure fuel pump then performs secondary pressurization, supplying a measured amount of fuel to each cylinder according to the engine's working sequence.
