What does it mean when a Volkswagen vehicle displays 'pressure loss detected'?
2 Answers
When a Volkswagen displays 'pressure loss detected', it indicates that under conditions such as high temperatures, increased tire rolling resistance, or greater friction with the ground, the internal tire pressure rises. The tire pressure monitoring system automatically identifies pressure when it is too high or too low and emits an alert sound. Upon detecting pressure loss, the driver of a high-speed vehicle should brake gently to avoid the risk of a tire blowout from emergency braking. The vehicle owner should turn on the hazard warning lights, place a warning sign behind the vehicle, and inspect the appearance of all four tires for any punctures or air leaks. Tire pressure monitoring system warning light remains on: If the warning light stays on after adjusting the tire pressure and performing a reset operation, it may indicate a malfunction in the tire pressure monitoring system. A common issue is a depleted sensor battery. Warning light illuminates during heavy load: Excessive vehicle load can cause tire pressure to exceed the preset upper limit. For models with an active tire pressure monitoring system, the driver can choose to either deactivate the system or adjust the load.
Having driven for many years, I've encountered this warning in Volkswagen vehicles several times. It means the tire pressure monitoring system has detected that the tire pressure is too low, possibly due to a puncture or a nail in one of the tires. Don't ignore it. If you feel the car is unstable while driving, especially on highways, the risk is significant. The tire may wear out quickly or even blow out. It's best to pull over to a safe place and use a portable tire pressure gauge to check the pressure. The normal range is 2.3-2.5 bar; if it's below 1.8, you should go to a repair shop to inflate or fix the tire. In winter, temperature changes can cause pressure drops, but false alarms from the system are rare—most cases indicate actual issues. Regular tire pressure checks can prevent this problem. Remember, don't delay handling it for too long—safety first.
