What is the appropriate idle speed for the Audi Q3?

Audi Q3 idle speed is mostly 550-800 rpm. Car idling: Idling is a working condition of the car, referring to the engine running in neutral gear. The engine speed during idling is called the idle speed. The idle speed can be adjusted by changing the throttle size, etc. Idling means the engine is "producing power without doing work". Idling classification: Normal idle: When the vehicle is in a parked state and the engine is started, the minimum stable engine speed is called the parking idle speed. Driving idle: When the car is in gear, without pressing the accelerator pedal or releasing the accelerator pedal while driving, the engine speed matches the parking idle speed, which is called the driving idle speed.
I've been driving an Audi Q3 for several years, and the idle speed of this car usually stabilizes at around 700 RPM. If you pay attention to the dashboard, you might notice that during a cold start, the idle speed can be slightly higher, above 800 RPM, but it drops to the normal range after a minute or two. I've experienced unstable idle speeds before, mainly due to carbon buildup or aging spark plugs. If not addressed in time, fuel consumption can increase, and the car may start to shake, affecting driving comfort. I usually recommend regular maintenance, such as checking the throttle body cleanliness every 10,000 kilometers, which helps maintain a stable idle speed. Additionally, Audi's engine management system is quite intelligent and automatically adjusts the RPM based on temperature and altitude. So, it's normal for the idle speed to rise slightly in high-altitude areas or when using the air conditioning in hot summer, and there's no need to worry too much about it.
As a daily driver of an Audi Q3, maintaining an idle speed around 700 RPM is considered ideal. After driving this model, I've noticed that excessively high idle speeds (above 850 RPM) waste fuel, while speeds dropping below 500 RPM may cause stalling, especially in heavy traffic. Once when my car's idle speed abnormally increased, inspection revealed a faulty oxygen sensor - replacing it promptly resolved the issue. Regularly monitor your dashboard display where idle speed is typically visible; frequent fluctuations might indicate MAF sensor issues or vacuum leaks. I recommend cleaning the air filter every six months to prevent dust accumulation affecting the intake system. Prolonged idling also harms the environment, so I consciously avoid letting the engine run idle for over 5 minutes when waiting.
