I noticed mouse poop (yes , I know what it is) smell in my 06 coupe a while ago which only got worse as I tried to ignore it .
While I didn't find it's source right off , I tried this stuff & by gosh it actually worked by putting under the drivers seat !

The cabin in the coupe is pretty tight (sealed off) from critters so the only mouse stink access must be the air intakes on the fuel injection --- YUP !
The pass side intake had evidence of mouse trailings so I removed both filters , cleaned all mouse residue w/ soap & water , blew out what little was in one filter & all is smellin good !!
Mice can get into the cabin via the air pressure balancing valves, one in each fender in the trunk, they are just fingers of rubber in a frame.
If they felt like it they could chew through rubber seals around wires etc.
One solution is to lock a cat in the garage with a car door open, just make sure the cat does not have access to the car key. Used cat litter in a few spots around the garage works as well.
