So my turbo has been making a fluttering sound when it starts to spool up still seems like it spools up fine but not quite sure why the hell its doing it. Oil was just changed about 500 miles ago. Any ideas much appreciated thank you

 

sounds like torn diaphragm in the dv.... replace with 710n or aftermarket piston style and be good

 

Exactly what I was thinking ^^^^^ Mine is doing the same thing and I have confirmed its the DV. Boost gauge?
