For sure some animal rest, could have run over a roadkill or a dead mouse somewhere in your engine compartment?

Also, make sure your a/c is NOT on recirc when you shut the car off. If it's super hot or you've only been in it a short time and it's still cooling down you may have to switch this back with the recir/fresh button, but it helps with keeping the system from growing mold and stink as badly.
edit - see elp_jc post below. I'm obviously way off on helping with this.....

The problem is mold. BMWs have had this problem for years with the vents. After a while, when using the AC regularly, the vents begin to smell like your feet. (Not my feet, your smelly bastards)
Not to spook you but, I have yet to find any solution for this once the smell starts. Whether you change the cabin filter or sanitize the vents is only a temporary fix. With my last two cars I have a couple of things I always do to prevent it. 1) leave the re-circulation off; 2) always turn the AC off a ways before I get to my destination and leave the vents going to dry out the AC condenser. That should help

The root cause of the odor IMO is BMW, in all its German wisdom, shuts off the vents when ignition is turned off, even if you had them in 'fresh'. You can confirm that no air gets in the car by shutting off the fan when in 'fresh' mode. In all other cars, you can keep getting air thru the vents with the HVAC off. On BMWs, it immediately turns into 'recirc' mode when ignition and/or HVAC system is turned off.
That's why it's so important to turn compressor off as far back from your destination as you can stand, to evaporate all condensation in the condenser. |

Check, also, that the condensate drain is not plugged up. The plugged drain can also lead to stagnant water formation and subsequent bacterial growth.

Just to give everyone an update - I did apply the Klima-Cleaner last weekend, and so far so good. Smell is GONE when I use AC through the front or bottom vents. There is a slight musky smell when I use the defroster - I'm guessing some bacteria is in the front vents that go to the windshield, I may use the second bottle next weekend and try and clean that out. But overall - I have to say I think the product worked very well. And I really do like the smell - it has a nice minty fresh smell that is quite pleasant. The minty smell has weakened over the past week, but there is no bad smell anymore. Hopefully this lasts! |

Hoping I don't get this smell. My car only has 4k miles and it still kind of has a new-ish smell to the interior. I don't like using Air Fresheners and stuff in the car... I feel like they add an unnatural scent to the car. Not a bad thing, just different. Obviously, if the car stinks, you need to do something about it, but I haven't done anything to mine yet. I've been lucky since no one eats/drinks in the car, no spills, nothing like that.
Hope mine doesn't start stinking! Good luck with your car!

There's no plug, per se. The place where the condensate drains away from the coil can get plugged with a pebble or somesuch. It's a fairly common problem, and easy to fix.
