Thinking turbos are going. When i turn the car on after being cold, hear loud whooshing noise....
then it stops all of a sudden. Pulled 4 codes yesterday, so i cleaned DV's and checked the N75 and it seems fine. now today one of the four popped on, 17819 - secondary air injection system - bank 2 -insufficient flow. The ones yesterday were
17964 - Charge pressure
17831 - Secondary Air injection - Bank 1 - insuff
17819 - same as today
17963 - Charge Pressure
they surged. yeah turbo lady is knocking on my door. Lets go warranty. Anyone have a tech replace oil feed lines while in there? Is it pretty pricey? Anyone pull these same codes before turbos went bad, still have full boost....
Thanks.

tips cars have secondary air injection and you have related codes
that's my bet, not the turbos. My old S4 was a tip car and it ran loud for 15-30 seconds on cold start-up, then the noise shut off. Was this true of your car before? Is the timing of the new noise similar?

this is not normal at all. It just started and CEL came on right after, the noise you hear...
is most likely a whistle, air pump that is cold. I have that also now i have an incredibly loud whooshing noise coming from the drive side turbo.
