What are the reasons for the tire pressure monitoring alarm in Volkswagen Tiguan L?
2 Answers
Volkswagen Tiguan L tire pressure monitoring alarm is mainly caused by abnormal tire pressure, tire pressure monitoring not being reset, or damaged tire pressure sensors. Abnormal tire pressure: Generally, the alarm will be triggered if the tire pressure is below 1.8 bar or above 3.0 bar. At this time, tire inspection and pressure adjustment are required. Tire pressure monitoring not being reset: After inflating the tires, if the tire pressure is not reset in time, the tire pressure monitoring system will still record the original data, causing the tire pressure monitoring indicator light to illuminate. In this case, simply reset the tire pressure. Damaged tire pressure sensor: The tire pressure sensor is used to monitor tire pressure and is directly installed inside the tire, connected to the tire inflation port. If the tire is hit while driving, damaging the tire pressure sensor, it will also cause the tire pressure warning light to come on. For sensor damage issues, only a brand-new replacement part can be installed.
The most common reason for a tire pressure monitoring system (TPMS) warning is insufficient tire pressure. This could be due to a tire leak, temperature changes affecting pressure, or a puncture. I've experienced this myself—while driving on the highway, the warning light suddenly came on, startling me into pulling over to check. I found that the right rear tire pressure was low, caused by a nail puncture. The slow leak triggered the system's warning. The solution is to first stop and use a tire pressure gauge to measure all tires, ensuring the pressure is within the standard range (usually indicated on a label near the driver's door). If the pressure is normal, it might be a sensor issue or a false alarm, which can be reset via the vehicle's TPMS settings. If warnings occur frequently, the sensor battery may need replacement, or you should visit a 4S shop to check the wiring. Regular maintenance, such as checking tire pressure every two weeks, can effectively prevent issues. Safety first—don't ignore it.
