Volkswagen fan keeps running for the following reasons: Insufficient coolant: Engine overheating caused by insufficient coolant leads to continuous operation of the electric fan. Radiator leakage: Engine overheating caused by radiator leakage, loose or damaged hoses causing water leakage, resulting in continuous operation of the electric fan. Thermostat failure: Thermostat failure causes the temperature to reach the baseline but unable to send water to the radiator, or sending too little water, leading to engine overheating and continuous operation of the electric fan. Coolant temperature too high: When the coolant temperature is too high, the vehicle's computer automatically calculates the fan speed and duration. The higher the temperature, the longer the fan runs to protect the engine.

Where is the reversing radar buzzer located on the Skoda Superb?

The reversing radar buzzer is installed near the steering wheel. In most cases, it is located on the lower side of the dashboard or the left side of the center console. The principle is that it should not affect driving or aesthetics. The reversing radar system consists of several components, including the main unit, display, sensors, and buzzer. The sensors must be installed on the front and rear bumpers of the vehicle to better monitor parking distances. Additional relevant information is as follows: 1. Introduction: The full name of the reversing radar is the reversing collision avoidance radar, also known as the parking assistance device. It is a safety assistance device used when parking or reversing a car, composed of ultrasonic sensors (commonly known as probes), controllers, and displays (or buzzers). It informs the driver of surrounding obstacles through sound or a more intuitive display, eliminating the hassle of checking front, rear, top, and bottom when parking, reversing, or starting the vehicle. It also helps the driver overcome blind spots and unclear vision, thereby improving driving safety. 2. Principle: The reversing radar is designed based on the principle that bats fly at high speeds in the dark without colliding with any obstacles. The sensors are mounted on the rear bumper. They can radiate within a maximum horizontal range of 120 degrees and a vertical range of 70 degrees, searching for targets in all directions. Its greatest advantage is the ability to detect obstacles that are lower than the bumper and difficult for the driver to see from the rear window, such as flower beds, curbs, or children playing behind the car, and then alert the driver.

Can Changing the Oil Fix a Water-Damaged Transmission?

Simply changing the oil cannot solve the problem after water enters the transmission. Generally, water settles at the bottom of the gear oil in the transmission, so it is necessary to open the bottom of the transmission to remove both the water and oil, then refill with new transmission fluid. It is also advisable to replace components such as gaskets, oil seals, and friction plates to extend the service life. If the water damage is severe and affects functionality, professional repair at a service center is required. Typically, transmission water ingress is caused by the following two scenarios: 1. Water submerging more than two-thirds of the wheels: In this case, the probability of water entering the transmission is around 80% to 90%. If the water level reaches the dashboard, the transmission is 100% flooded. 2. Water splashing into the transmission during oncoming traffic: If there is excessive standing water on the road, splashes hitting the vehicle body may also cause water to enter the transmission. When water contaminates the transmission, the performance of the transmission fluid is severely compromised—not only is its lubricating ability reduced, but its power-transfer efficiency also declines. This can lead to clutch slippage, followed by a rise in oil temperature, which may generate steam or even cause the oil-water mixture to boil. These viscous residues can accumulate in the valve body, clogging it and affecting the transmission's control system.
