What does it mean to replenish air in a Porsche?

When the Porsche dashboard indicates the need to replenish air, it is a signal for tire pressure warning, indicating that the tire pressure value is too low and the tire requires inflation. After inflating, a tire pressure reset needs to be performed, followed by replenishing the air, and the warning will then disappear. Below is an introduction to the tire pressure gauge: 1. A tire pressure gauge is a type of air pressure gauge for tires. It consists of a gauge head, piston, gauge body, scale, main spring, etc., with only one air pressure measurement port on the gauge head. 2. It features a simple structure, small range, high accuracy, and ease of use. 3. The standard tire pressure for ordinary car tires is 2.5kg for the front wheels and 2.7kg for the rear wheels in winter; and 2.3kg for the front wheels and 2.5kg for the rear wheels in summer.
When I previously worked with Porsche models, I noticed that the supplemental air system is actually a secondary air injection function. During cold starts, the engine draws additional fresh air into the exhaust manifold to re-burn unburned hydrocarbons, thereby reducing pollutant emissions. This system primarily relies on an electric air pump and a one-way valve to operate, and it typically only activates when the engine hasn't reached its operating temperature. Common failures include burnt-out air pump motors or carbon buildup causing valve jamming, and sometimes it can even trigger the engine malfunction light. I recommend regularly checking the system's hoses for air leaks, especially paying attention to connector corrosion during humid seasons. Porsche's design is quite eco-friendly, but repairs can be really expensive.
