Ok. From my understanding of the Auto it has over rev and mechanical protection for the downshifting so it won't let you down shift if the conditions might cause an over rev or mechanical issues for the trans. 4K does't sound like it's too much though. How is it now? A start cycle may have cleared the issue.
Maybe the system just says OK too much noise. It's debateable in reality whether exhaust pops and crackles are technically legal on a road registered car. Maybe BMW limit the amount or amount in a given time to address this. Try doing it over an extended period of the same drive not in a brief succession.
If you read my initial post I found this "problem" at the track. I track this car very often and only for track. I always try to push my car to its limits and I tend to downshift very frequently during corners to retain power and not for "no reason". I think its very immature of you to comment what you commented ("Dumb and dumber that’s why") without context. Not every supra owner drives on the road only. Please reevaluate and think what you comment before saying something unnecessarily negative...
thank you!
