EDIT: Just when I was feeling happy with improved bass, I had the SZL replaced for "cruise control malfunction," which required reprogramming, and now feels flat again. I checked with Bimmercode, and shows F45 is the EQ setting. Does it make sense the audio would change with reprogramming and now not "take" despite an F45 profile selected?
