My stock 2012 RRS SDV6 (old shape) has started making a turbo flutter noise when the throttle is released after putting the engine under load. happens in certain conditions underload or if I hold the break give it some revs and let off while in drive.

I've inserted a youtube vid here of the exact same noise I found on youtube



Cant find any advice on the net specific to LR just a consensus this is not good in general (if it is flutter / surge).

Steeler is telling me this is normal, a normal intake sound. What are your thoughts. I was wondering if anyone has the same noise and it is infact normal. Is this normal? or a turbo failure in the making / misbehaving BOVetc A

Any advise would be much appreciated

thanks
PS i have posted this in the wrong section previously (no repsonses) so reporting here as i'm back off to the steelers later today
