What is the reason why the tire pressure warning light of the Sagitar cannot be turned off?

The reason why the tire pressure warning light of the Sagitar cannot be turned off is due to abnormal tire pressure, and it is necessary to check the tires. Generally, the normal tire pressure is around 2.3 to 2.5 bar. In winter, it can be appropriately increased by about 0.2 bar. In summer, due to higher temperatures, the tire pressure can be reduced by 0.15 bar compared to the standard tire pressure to avoid high-temperature tire blowouts. The Sagitar is a compact family sedan under Volkswagen, with a body length of 4753 mm, a width of 1800 mm, a height of 1462 mm, and a wheelbase of 2731 mm. The Sagitar uses two engines, one is a 1.2-liter turbocharged engine, and the other is a 1.4-liter turbocharged engine.
My Sagitar's tire pressure warning light keeps coming on and won't turn off. I think it's most likely a tire issue. For example, there might be a slow leak caused by a small nail puncture, leading to uneven tire pressure; or the sensor battery might be depleted—some older cars experience sensor failures after a few years of use. It could also be that the reset operation wasn't performed correctly. When turning on the ignition and pressing the reset button, you need to wait a few seconds. If the system is still in the learning state, it might get stuck. I've encountered this situation before, always thinking a simple fix would work, only for the light to come back on after driving for a while. Tire issues can affect driving safety, especially on highways where incorrect tire pressure can cause the vehicle to skid or even lead to a blowout. I recommend first checking if the tire pressure meets the standard—generally, around 2.3 bar for the front tires and 2.5 bar for the rear tires is ideal. If the light still won't turn off after trying the reset, take it to a professional shop immediately to check the sensors or wiring. Don't wait until an accident happens.
