Can't be any worse then not changing the cabin filter in a PM.

Personally I would focused on cooling the condenser coil itself.
on my M3 too ,,, BMW Dealer would spray Lysol or a similar product into that Petri dish HVAC box

I’m starting to smell the same odour outta my 2018 Ram Pickup & it just had the cabin filter replaced ,,, Time to learn how to Lysol it myself I guess.
