My 2018 MINI STINKS, literally. Help MOLD!
 

Yipes, just got into my car this morning and it stinks inside. Stinks like, "Who left the fish sandwich under the seat stink?". Well, no fish sandwich to be found. I did, however, discover a bed of mold growing in my trunk. I have the 2018 Mini Cooper S 4-door. I lifted the recessed trunk cover up and low and behold moisture and mold. The mystery is how did the moisture get there? Anyone have any experience with this? I hope you don't but if this sounds familiar I would be grateful for anything you can share. I did a forum search but nothing similar so apologies if this is a redundant post. First time poster.
