Is an idle speed of 1000 rpm normal for an Audi Q5L?
3 Answers
Audi Q5L's normal idle speed is around 700 to 800 rpm, 1000 rpm is abnormal. Introduction to idle speed: Idle speed means the engine is running without doing work. It is an operating condition of a car, referring to the engine running in neutral gear. The engine speed during idle is called idle speed, which can be adjusted by changing the throttle opening size. Idle conditions: Normal idle: When the vehicle is in park and the engine is started, the minimum stable engine speed is called parking idle. The process of the engine transitioning from cold idle to normal operating temperature idle is called warm-up or heating. Driving idle: When the car is in gear without pressing the accelerator pedal or when releasing the accelerator pedal while driving, maintaining the minimum throttle opening, the engine speed matches the parking idle speed, this state is called driving idle.
As a long-time Q5L owner, my car usually idles steadily around 700 rpm. A sudden jump to 1000 rpm is definitely abnormal—it could be due to carbon buildup or dirt in the throttle body affecting air intake, or a faulty oxygen sensor causing inaccurate ECU signals. I once experienced high idle at 900 rpm, with fuel consumption spiking by 10%. A 30-minute throttle body cleaning at the repair shop fixed it. A higher idle when cold-starting is normal, but if it stays at 1000 rpm after warming up, check the ignition system. Ignoring this not only wastes fuel but also damages engine components. I recommend using an OBD scanner to read fault codes or visiting a professional shop—don’t cut corners and risk bigger issues.
As an automotive enthusiast, I've studied engine idling. The normal idle range for the Q5L's 2.0T engine is 650-800rpm, and 1000rpm is too high. Typical issues include ECU control malfunction or MAF sensor failure causing incorrect fuel mixture ratio. Sometimes vacuum hose leaks can also push up the RPM. After warming up, it should drop to a reasonable value - persistent high idle indicates potential faults. Pay daily attention to whether the engine sound is steady. If abnormal, don't delay - go directly to the dealership for computer diagnostics. After repair, the idle will be smooth and fuel-efficient.
