Is it normal for the Mercedes GLC to idle at only 600 RPM?
2 Answers
The Mercedes GLC idling at only 600 RPM is not a normal phenomenon. Common causes of low idle speed include: a dirty throttle body, excessive carbon deposits in the cylinders, a faulty idle control valve, poor atomization or clogging of the fuel injectors, changes in oil viscosity, etc. Normal idle speed refers to the minimum stable speed at which the engine operates without load and without needing to perform external work. More information about car idle speed is as follows: 1. Idle speed is an operating condition of a car, referring to the engine running in neutral. The speed of the engine at idle is called the idle speed. The idle speed can be adjusted by changing the size of the throttle, etc. Idle speed means the engine is "working but not performing labor." 2. When the engine is running, if the accelerator pedal is fully released, the engine is in idle condition. When adjusting the idle speed, the speed should not suddenly increase or decrease, as this can cause premature wear to the engine. It is best to have the idle speed adjusted at an automotive repair facility.
Hey, I've been driving a Mercedes GLC for several years, and an idle speed of 600 RPM is indeed normal. Especially for my car, which is equipped with energy-saving technology, it's actually good for the idle speed to fluctuate between 600 and 800 RPM—it saves fuel and keeps things quiet. I usually pay attention to whether the tachometer is steady; if it's stable without any shaking, then everything is completely fine. Of course, if you're still a bit unsure, you can observe the idle speed when the car is cold started—it's normal for it to be a bit higher then. The key factors are the car's age and maintenance: regular oil changes and carbon deposit cleaning can prevent issues. Last time my car had a slight idle shake, the mechanic just changed the spark plugs and it was fixed—simple and not expensive. In short, this is how Mercedes designs it, so drive with confidence!
