Hi!
Looks like it is overboost protection is working.
It can be westgate on turbo or this valve

having same problem on my gu 2.8tdic,when boost picks up good suddenly it drops and a whinding/whisling noise appears !
If someone know what to chack for please let me know !
s wine maker suggests, most likely the poppet valve on the manifold. I took mine off and plugged the hole, didn't affect anything, was a 1997 2.8TD GQ. Facory turbo never pushed mare than 12psi with or without it, just lost the annoying whistle/chatter.
mine is a gu it doesnt have that thing on the manifold
Just use the cheaper non synthetic oil and you will be fine. I have done this for years and found the vehicle was a bit quieter in operation, no other positives I can detect - some claim power increases, torque increase, lower soot - have not seen any of these.
