What is the normal idle speed for an Audi Q7?
2 Answers
Audi Q7's normal idle speed ranges between 600 to 800 RPM. The Audi engine comes with a protective function - when stationary acceleration is applied without vehicle speed signal, the engine won't exceed 4000 RPM for protection purposes. If the accelerator is held down continuously, it will automatically return to idle state after a while, requiring the driver to release and reapply the accelerator. The Audi Q7 is a mid-to-large luxury SUV that emphasizes comfort, skillfully integrating sportiness, functionality, high-tech features and premium quality. It's equipped with four-wheel steering system: during low-speed turns, the rear wheels turn in opposite direction to reduce turning radius and driving trajectory width; at high speeds, the rear wheels turn in the same direction to enhance wheel response, dynamic performance and stability.
I remember driving my friend's Audi Q7 a few times, and after starting, the tachometer showing between 650-750 RPM is considered the normal range. I found it quite smooth with very little engine noise, and it's fine if it rises to around 800 RPM when the AC is on. If the idle speed fluctuates significantly, like dropping below 600 RPM or exceeding 850 RPM, there might be issues such as carbon buildup or sensor failure. In such cases, the car may shake, and fuel consumption could increase. Last time I helped someone check, we found the throttle body was a bit dirty. It's best to get regular maintenance and have the repair shop scan for trouble codes with a diagnostic tool to prevent small issues from becoming major problems. In short, it's normal for a new car to have slightly higher RPM during a cold start, but it's ideal for it to stabilize and stay within that range afterward.
