Hey everyone, is it normal for the car's RPM to stay around 1200 even when I release the accelerator while driving? The idle speed is only 800 RPM when parked in neutral. Is it the same for you guys?

When starting a cold car, the RPM goes up to 2000 and then drops to 1500 but doesn't go any lower. The high idle speed is causing high fuel consumption, 20 liters for 300 kilometers! The idle speed is too high, and so is the fuel consumption. Can any experts provide a solution? 🙏

After refueling my Jetta VS7 at the gas station, the idle speed tends to be high, around 1000 RPM. Then, during driving, the speed fluctuates. After driving for about ten kilometers, the idle speed returns to normal. Alternatively, if I turn off the engine and restart it, the idle speed also normalizes. I've tested this each time I refuel, and it's always the same situation.
