As for the PS, I cranked the wheel from lock to lock a few times and left the car on for a few seconds before turning it off, per DIY guide for PS flush, and it seemed a bit better. I'll have to keep an ear out for the noise and report back.....I really hope it's not the active steering rack or the column.....fingers crossed!
N54 or N52? Either way, it's an exhaust prob I haven't seen - anyone?

There's just gotta be a good PS fluid flush DIY - maybe the one you've accessed. Have not done it myself, but if dirty, certainly worth your time. Likely uses little fluid & is inexpensive.
