I have a 2002 325i. I dont know what each one of these engine parts are.
The one in the red has broken mounts on it and the one in the yellow is really greasy. I got the car 2 days ago and didnt buy a repair manual yet. thanks.

It is an air pump.which kicks in for a few minutes when you first start the engine in the morning(cold engine) to help reduce engine emission in the warming up period
