She had the dealership do something to it, and it worked for a while, but eventually the smell came back. I just can't remember what they did, but thought it was something with the a/c. Sorry that's not super helpful...
See below, but yes it's kinda all tied together but the panel breaking down seems to be right where the hvac system is so it makes sense. I have heard of other f series cars fixing it with a panel behind the dash that was degraded and offgassing this smell. I really want to track it down as best as possible without destroying the daily ripping the whole dash apart to find it. I will if I have to, but I really don't want to. It started mild but it is growing with age. I've done all the usual stuff cabin filter etc. it's 100% distinct crayon and if you Google bmw crayon smell you will see I'm not crazy at least lol. I just need to pinpoint the source of it on the e84 platform.

No it's a common issue with bmws and apparently other German cars. It's got to do with insulation/sound deadening material breaking down from what I've researched so far. Between the dash and engine bay somewhere.
