What causes the Volkswagen tire pressure light to illuminate?
1 Answers
The reasons for the Volkswagen tire pressure light illuminating are abnormal tire pressure, unreset tire pressure monitoring, or damaged tire pressure sensors. Abnormal tire pressure: The system typically triggers an alarm when pressure falls below 1.8 bar or exceeds 3.0 bar. In this case, tire inspection and pressure adjustment are required. Unreset tire pressure monitoring: If the tire pressure monitoring system isn't reset after inflation, it continues to record previous data, causing the warning light to illuminate. Simply performing a tire pressure reset will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, installed internally and connected to the tire's inflation valve, monitors tire pressure. If damaged during driving (e.g., by impact), it triggers the warning light. Sensor damage necessitates replacement with new components.
