Might be a good time to replace your pollen filter too.

I've been thinking this might be why I get a smell in my new-to-me 135i. PO had mice, after cleanup including Ozone Generator, and shop inspection reporting no further signs of mouse damage, it came back and I decided it smells kinda like burnt oil. Shop had found a small oil leak at the valve cover gasket, and will replace gasket tomorrow (and valve cover if it's got any issues). Hope that cleans up the smell.
