hello. yes i did read the whole post and looks like the problem is with the rear differential in 4\4 models sending the noise via heating vents to the cabin. You can stop the noise at any speed by switching to neutral . i did talk to my local dealer about this so lets see how they can fix that. I know for sure is not a panel or a tape issue in this case but the noise it is same as the one on your video just little quieter.

Update: I have been working with my dealership on the issue of high-pitch whine transmitted through the air vent. The lead technician and service manager at my dealership have been excellent. They escalated this issue several levels through PCNA and then finally to Porsche in Germany. Porsche has acknowledged the issue of a harmonic frequency sound transmitted through the air vent opening in the engine bay. My dealership has been told that an extension piece is being developed that will be added on the current vent opening to eliminate the sound intake. I was told to expect "a few weeks" for the work-around to be completed. When I expressed skepticism regarding the speed at which Porsche would actually develop and release a fix, I was told that this was apparently being taken very seriously by Germany due to the number of Panamera's reporting the issue - they realize this is not an isolated problem.

I asked about the ti-al turbo reality when I saw one ptts burn at Shannonville, I think it was almost a year before the recall arrived. They usually fix these, but it will take time. I think they need a fix that can be made for all the cars and without big costs.
Sorry your fix isnt as easy as mine...

I am based in the UK and own a brand new panamera 4s. Immediately I noticed the exact same problem re high pitched noise which is variable as to throttle input. It also occurs at 54 and 71mph. I informed Porsche UK and their response was to reprogramme the transmission software, which is now taking place. However, so far their systems keep crashing and I was told that it is due to a programming problem with the agents diagnostic equipment, which in turn would corrupt the information being stored in the vehicles ECU's. I am doubtful this will rectify the fault. Does anyone have any further insight into the resolution of this annoying problem??????
