Sprung for a iOS based coding app (BimmerCode ($30)) and while I was getting rid of the legal disclaimer iDrive screen and turning off the headlight washers, tried coding out ASD to observe the difference on a US spec 2017.
Wasn't dissatisfied with ASD per se, but, in a highway/cruise control situation, hard to imagine MORE steady state noise being desirable. And with this app, easily reversible, so why not give it a go?
First quick test drive impressions:
- Definitely noticeable difference in all modes, but really interested in an getting out for an interstate cruise to see if it's noteworthy
- I now can hear the workings of the turbo if I listen for it with the sound stereo system "off". With ASD on, I'd never before noticed it.
Will leave it for a few days, and form some further conclusions, but as easy as this is to turn on and off, could easily see me turning it off for long highway trips at least.
