Piping/jaming turbo

Hello, on Friday I picked up my 2.0 TDI in Ingolstadt. On the way home, just after a few meters I noticed, that if I give gas or take away my turbo / motor creates com mushy noises. It sounds like a bellows bellows that whines a bit or whistles. My 1.9 TDI did not make these noises. Is that normal? Oh yes and what else, when accelerating in the speed range from 1800 to 2500 I have quite a vibrating noise that comes from the rear area. mmen. Listens to itself as the rear window or trunk flap vibrates. Not again a Monday car….
