What does the 'Store Tire Pressure Again' prompt mean in the Tiguan?
2 Answers
The 'Store Tire Pressure Again' prompt displayed in the Volkswagen Tiguan indicates that the tire pressure of the vehicle has changed. In such a situation, it is essential to safely stop the car and inspect all four tires to ensure they are in normal condition. If any tire shows obvious signs of air leakage, promptly take the vehicle to a repair shop for tire maintenance to resolve the issue. There are three commonly used methods for tire pressure monitoring: Direct Tire Pressure Monitoring: This system uses pressure sensors installed in each tire to directly measure the tire pressure. The pressure data is then transmitted wirelessly from inside the tire to a central receiver module, which displays the pressure readings for each tire. The system automatically alerts the driver if the tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that tire to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the differences in rotation speeds between the tires, the system monitors the tire pressure. Indirect tire pressure monitoring systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Tire Pressure Monitoring System (TPMS) Overview: This system combines the advantages of both the direct and indirect systems. It is equipped with direct sensors in two diagonally opposite tires and includes a 4-wheel indirect system. Compared to a fully direct system, this hybrid system reduces costs and overcomes the limitation of indirect systems, which cannot detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time pressure data for all four tires as effectively as a direct system.
The 'Reset Tire Pressure' prompt on the Tiguan means the vehicle is reminding you to reset the tire pressure monitoring system data. This system monitors tire pressure via sensors, and if it detects abnormal data or you've recently adjusted tire pressure, this alert will appear. Ignoring it may result in persistent dashboard warning flashes, making driving uncomfortable. As someone who frequently drives my own car, I recommend first checking if the tire pressure is normal—use a simple tire pressure gauge to measure each wheel. If all readings are correct, locate the reset button inside the vehicle (usually labeled 'SET' or 'Tire Pressure' on the center console) and hold it for a few seconds to complete the reset. If the issue persists after resetting due to faulty sensors or wiring problems, it's best to visit a professional repair shop promptly to avoid long-term impacts on tire lifespan and braking performance.
