Is it normal for the Mercedes GLC to idle at only 600 RPM?

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!

As someone who frequently deals with cars, a Mercedes-Benz GLC idling at 600 RPM falls within the standard range, especially for models with auto start-stop. The key is to observe whether the RPM remains steady without fluctuations. Issues may arise from carbon buildup or sensor malfunctions. I recommend regularly using diagnostic tools to check OBD codes to prevent minor issues from escalating. If the RPM fluctuates or the engine stalls, it's time to inspect the air filter and clean the throttle body. Don't neglect regular maintenance cycles, as ensuring smooth fuel flow can prevent malfunctions. Overall, as long as the car runs smoothly without abnormalities, this idle speed value reflects thoughtful design.

Hey, your Mercedes-Benz GLC idling at 600 RPM is absolutely fantastic! My car often does the same, and low RPM indicates an efficient and fuel-saving engine, making city driving super worry-free. However, it's normal to notice higher idle speeds during cold starts. If you ever feel the car shaking or the idle becomes unstable, a simple cleaning of the fuel system or spark plugs might do the trick. I make it a habit to check these details during regular maintenance to extend the car's lifespan without much hassle. In short, with Mercedes' advanced technology, 600 RPM is no issue—just enjoy the ride.
