Hi all. My vehicle is M57/T2 engine. Recently she came out with the "duck" noise from engine bay (People said from internet). Moreover, I felt the sensitive of performance became a bit drop. I tried to use Carly OBD2 program and no faults related from this. I done plenty of research and I defined it should be pressure converter problem.

Can anyone have this situation before? Hopefully is the hose small leaking. Please share your experience due to I am going to disassemble on next weekend and check it out.

Please click into the links to hear the weird sound as below.

By the way, if anyone have those of parts please PM if possible. Many thanks!

Part number: 11747796634, 11727545323, 11747797082
