Hey guys, my loved 320d has had a BRAND NEW turbo about two months ago when the old one blew. It drives perfectly fine and boosts perfectly fine too. Power is delivered smooth and doesn't slack at all at any times. However, my car 'turbo chatters' when I am partially on boost and let off the throttle.

This is what I mean:

It doesn't do it at all while on throttle so it is NOT COMPRESSOR SURGE!! It's very quiet, however I love the sound. I'd like to know if it's normal for it to do that from time to time though, since I thought diesels can't do that due to them not having a throttle plate.

Thanks for any help :D
