I would pull the consol now and make sure there isn't any coffee ice in there.
Get a stiff brissle detailing brush, carpet cleaner (auto glym or chem guys), and steam. You'll have to put in some Elbow grease to get it all out.
If it still stinks I would pull the carpet and pressure wash it. I did that with my old cross sport seats that were heavily coffee stained and they turned out great.
