I need some advice from experts: I have a 2013 1.4T Touran. Recently, the engine occasionally makes a loud noise after starting, and the idle speed is over 1100. But after turning off and restarting, the engine sounds normal, and the idle speed is around 700, back to normal. What could be the issue?

Hey everyone, what’s the fuel consumption of your Alto automatic? I feel mine is too high, 24.5 liters only covers about 300 km. The light came on at 287 km.

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.
