Why can't the Audi Q3 display tire pressure values?
2 Answers
The Audi Q3 series has canceled the tire pressure monitoring function and only retains the tire pressure warning feature. Hazards of excessive tire pressure: Reduced tire friction and adhesion, affecting braking performance; causes steering wheel vibration and deviation, lowering driving comfort; accelerates wear on the central tread pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting the longevity of other components. Decreased puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, causing internal cracks or blowouts due to impact, leading to tire bursts. Hazards of insufficient tire pressure: Increases friction coefficient with the road surface, raising fuel consumption; results in heavy steering and deviation, compromising driving safety; increases movement of tire components, causing abnormal heat due to excessive rolling; degrades the function of cords and rubber, leading to delamination or cord breakage, and excessive friction with the rim causing damage to the bead area and abnormal wear.
I find this issue quite common, probably because the Audi Q3 uses an indirect tire pressure monitoring system instead of one that displays numerical values directly. Simply put, it detects tire pressure changes through wheel speed sensors but doesn’t show specific pressure values on the screen—only triggering a warning light when pressure is abnormal. My car is also a base model Q3 without real-time tire pressure display, which is a bit disappointing, but I’ve heard the luxury version or aftermarket upgrades can fix this. For safety, I manually check the tire pressure with a gauge once a week to ensure it’s within the recommended range, which saves fuel and prevents excessive tire wear. Some fellow car owners shared that dealerships can reprogram the system or install additional sensors, but I find it too expensive and prefer doing it myself. Overall, the design leans toward cost control, but developing this habit is good—stable tire pressure definitely enhances driving stability.
