The newly bought car has only driven more than 3000 kilometers. Why is the engine bright yellow?

Hello, you'd better go to the 4S shop to check it out. Whatever the reason, it is within the warranty. Poor air quality is just one of their many perfunctory means. Hehe, I remember there are too many words in the specialty store that we don't understand. The only problem is that the car is still under warranty. For example, he said that the throttle is dirty, so the throttle belongs to the engine, so it is an engine problem. Oh, so can the engine problem be replaced at this kilometer? Then let's talk about the engine problem of this kilometer.
