Do 4S shops usually wash the engine bay during maintenance? Yesterday was my first service, and they didn't even cover the steering wheel or seats. There was water, which looked like oil in the workshop, and it turned out they washed the engine bay while the car was running. Now, when I start the car in the morning, it revs high for a while. After the service, the revs are higher and last longer than before. There's often a rattling noise on the dashboard; when I press it with my hand, it stops. How can I fix this?

Hello everyone, when I start the car and reverse while turning the steering wheel, does anyone hear a noise from the lower control arm? It goes away after a while! My car has done 110,000 kilometers. The engine also makes a rattling noise when starting, and the RPM is over 1000, but it settles down in a few seconds! I suspected the chain, but since the RPM is also high, I ruled that out! Has anyone experienced something similar?
