How to Reset the Tire Pressure Light on a Passat?
1 Answers
Adjust the tire pressure to the standard value and perform the tire pressure system setup. The specific setup method is as follows: Turn on the ignition switch, press and hold the setting button for more than 2 seconds until the instrument panel emits a "ding" sound prompt. After confirming that the new parameters are stored, the warning light will turn off. The tire pressure monitoring system automatically monitors the tire pressure in real-time while driving, alerting the driver to tire leaks and low pressure to ensure driving safety. There are two common types: direct and indirect. Below are the related introductions: 1. The direct tire pressure monitoring system has pressure sensors and transmitters installed on each wheel. If the tire pressure of any tire is 25% lower than the recommended cold tire pressure in the driver's manual, it will alert the driver. Its warning signal is more precise, and if a tire is punctured and the pressure drops rapidly, the direct system can provide an immediate warning. 2. The indirect tire pressure monitoring device is much cheaper than the direct system. It actually uses the speed sensors on the car's ABS braking system to compare the rotation counts of the four tires. If one tire has lower pressure, its rotation count will differ from the others. By using the same sensors and sensing signals as the ABS system, the onboard computer can establish a new function in the driving computer with software adjustments, warning the driver that one tire has lower pressure compared to the other three.
