What's the issue when the tire pressure monitoring system in Volkswagen Touareg doesn't display?

Touareg's tire pressure monitoring system not displaying indicates that the tire pressure is too high. In this case, the owner should first check if the warning light on the dashboard is illuminated; then proceed to deflate the tires. If the tire pressure monitoring still doesn't display, it is likely that the built-in tire pressure monitoring module has malfunctioned, and it is recommended to have it inspected and repaired by a professional. Hazards of excessive tire pressure: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern of the tire, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overextends the tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, causing internal cracks or blowouts, leading to tire bursts.
With years of experience in car repair, I can say that when the tire pressure monitoring system (TPMS) on a Volkswagen Touareg doesn't display, it's mostly due to the tire sensor batteries running out. Those little devices inside the tires usually stop working after five or six years. Another possibility is that the system isn't properly calibrated, such as forgetting to initialize it after changing new tires or inflating them. Other causes include water damage and rust in the receiving module, or software bugs causing communication interruptions. I recommend car owners first check the dashboard menu and try manually resetting or inflating to trigger a response. If the problem persists, don't delay—go to a 4S shop or a professional repair shop immediately to read the fault codes. Remember, driving with tire pressure too low or too high can easily lead to loss of control and increase the risk of accidents. Safety first.
Last time I took my Touareg on a long trip, the tire pressure monitoring screen suddenly went blank, which kept me on edge the whole way. After checking for a long time, I realized the sensor battery might have died or the signal was interfered with; some people say this can happen in tunnels or strong magnetic fields. When I took it to the shop, the technician said they had to reset the system to fix it, and if it was a hardware issue, parts would need replacement. Now I’ve made it a habit to manually check the tire pressure every month to ensure there are no leaks. Don’t underestimate this—abnormal tire conditions can accelerate wear, affect fuel efficiency and comfort, so timely handling saves hassle.
