My 2020 110S P300 is continuing to collect a dead mouse/ chemical smell when closed up for several days.

We are very experienced with expired rodents in our vehicles. No evidence at all of this here.

could the seats / interior be out gassing? Anyone else experiencing this?

 

No weird smells for me that aren't personally introduced....But mine is only a month or so old. So, I'm interested in what you find but can't provide a data point.

 

Nothing in my P300.

 

Who could let a Defender sit for more than 24 hours? I'm making up excuses every day to drive somewhere

All kidding aside, no strange smells to report in my P300 either.
