When the air con of the car was off I had a weird bad smell coming from air vents with hot air. So I thought that I have to change the filters (inside and outside) on the car so I did. I still have a bit of HOT air coming from air vents and a weird smell and I was wondering if anyone is having this problem especially now that is summer and car tends to get higher temps.

There are quite a few threads on smell from the AC, I'm sure someone will chime in with experience.

I have searched but I didn't find any. I will search now again.

There is a pending class action lawsuit for the bad mold smell coming from the a/c.

Here is one website talking about it but the class action is still pending review by a judge

So shall I assume all c63/c63s owners have this issue? I cannot drive with the AC Off due to the bad/weird smell in the car. At least is any 3rd party spray or mod that I can do?

Here's an idea, do you work out and then go to your car without taking a shower at the gym? That smell happens to me on my old C350, but I haven't experienced it in my C63. Food for thought.

The solution is pretty much the same on every other car that has this kind of problem with a funky smell from the air conditioner: Remove the filter under the hood and spray lysol in there and do the same for the under the dash filter as well.

That is often not a permanent fix and you will have to do that each time you start smelling it.

No I have a small gym room home. I never put food or any other food grade stuff in the car other than coffee I have placed a light air refresher from Auto Finesse but the smell is still there. I also did full detailing inside and outside the car.

Already did that as I stated in the beginning. The reason I changed the filters and apply spray it was from the bad smell. But I am 100% the smell is coming from the Air Con while it's off ONLY. When it's ON it smell great.

The same as yours. 2017

Funny this came up - I just used my AC for the first time today since I bought it. It smelled like a cow pasture!! I turned the re-circulation option on and it went away so its not me . Bit different symptoms than op. I will be switching out the filter under the hood asap! Would have thought since it's a cpo it would have been changed out...

Went back and looked, you did not mention spraying Lysol.
