Good morning all,

My recent purchase 2012 4.4TDV8 has been making a turbo flutter/turbo stall noise on engine shut down, that I didn’t notice at the time of viewing - I’m trying to work out what it might be but wondered if anyone here has heard/had this issue before?
I’ve attached a link to a YouTube video of the exact noise on shut off - no other issues present or fault codes.

Thanks in advance all
