- OK, should have gone back and read the title of your post after watching the video... So when it is "whining" is when you are stepping on the accelerator?
This is my first turbo, so I am no expert, but the turbo will spool up when you accelerate, so that would by my first guess (like
mentioned previously) Are you monitoring Turbo boost via FORScan PIDs or via the IPC (pretty sure there is a setting in there to make one of the small IPC gauges display Turbo Boost) not that we know what to be looking for (maybe loss of boost due to leak in turbo?)
The sound is definitely not normal -- I know you are probably tired of going to your dealer by now, but I think this is an easy one to recreate while taking the Service Manager hostage for a test ride, and let them diagnose & repair while under warranty.
I must say that you definitely have the record for these one-off issues that no one else is experiencing (DPF Piping, vacuum leak around turbo donut, etc.)
