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

PS. Why does my turbo newer pushes more than 0.45 kg?

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.

Be careful doing this as some 2t oils contain zinc which is not good for injector nozzles (eg racing oil) and you may loose more performance.

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.
