Ok, let me start by saying I love the 5.6 update; everything runs more smoothly--and faster--from the maps to the web browser. One thing is weird though...I used to have the whine that comes from flooring it--often referred to as the pinched balloon whine--and after the update it's, well, different. Now, it happens less often at lower speeds, but at full throttle from 50 mph+ I now have a "double whine." That is, two separate and distinct whining noises starting a fraction of a second apart but coming from slightly different locations. It's not really noticeable with the stereo on, but very clearly audible without. Has anyone experienced this since the update? I have a 60kw MS, and this happens at speeds >50 at 240kw of power (completely floored, essentially). Is anyone able to replicate this...or for that matter confirm that it does NOT happen on their car? If it's the new normal, I will skip the service visit...
