More than likely it's your secondary air pump. Located top middle of firewall, makes high pitch sound on startup. Tech archieve has repair writeup.

if it sounds like a dentist drill then it's the turbos giving up. mine have been like that for 5k.

Sorry if took me so long to respond. It is not when boosting it is just in the morning. I will check the codes and let you know.
Thanks

Did you find the source - currious to know the outcome

mine did as you describe, so I decided it was time to upgrade before a complete turbo failure (passenger side turbo turbine shaft had excessive play [movement])

My High-Pitched Sound was the Tiptronic Eating Itself (Apparently)

I'm late to this party but I'd like to add:

New trans in = whiny/whistling gone.

Just my $0.02. YMMV.
