hi guys,
We got a lot of rain not too long ago and my street got flooded, my car was parked on the street and when i looked out the window, im pretty 1/2 to 3/4 of my rims were covered in water. Not sure if this has anything to do with this weird smell but the water soaked thru into the back seat, the mats were all wet, water didnt get to the seats though.

Now when i turn on the a/c it works fine but theres a weird smell that comes with it, kinda smells like wet clothes or something.. What do you guys think it is? Could it be that the cabin filter got wet or something??

 

You still have moisture inside your car probably under the cushions and carpet.
If i were you i would tear apart the whole interior and use one of those industrial Wet-Vacs to vacuum out any moisture and then use one of those Rug shampoo machines after you have left the car in the sun with no interior for a day or 2 so whatever little dampness is left is dissipitated(open a box of Baking soda in there for good measure to absorb some of the bad smell). After shampooing the interior and leaving it for most of the day in the sun put your interior back in and you should be good.
Changed the Cabin Filter for good measure

 

umm the smell is only when the a/c is on..

 

Sounds like mold to me. This also happens when you have A/C on for a good amount of time and then suddenly turn off the car. Once you're car is on and the A/C is running again, you will probably have the same smell that you have described. Usually when I have my A/C on for a long time, I turn the A/C off and just have the fan blowing for about a minute before turning the car off. If I don't do that before turning the car off I will get that moldy smell similar to yours.

 

does it smell likes clothes tat hasnt been washed for like 2monthes? LFMao
the same thing happening in my bros a4, would it be mold in the filter?

 

try changing out the cabin filter

 

+1 on the new cabin filter.

Try the baking soda and shampoo also. That should clear it up, but do it all at the same time.

 

+1 on running just the fan a minute or two before shutting your car off to get the moisture out

 

Once I saw that you said there was water in the car all the way up to the back seat.
I don't know about but im a clean freak when it comes to my G. I will go the extra 100 miles to get my car back to stock or better.

So if i was in your situation I would do exactly what I posted but thats just me

 

My car had that smell last summer (without getting soaked). It went away after about 2 weeks. No filter changed or anything else.

 

Start turning your air off about a minute before you turn off your car too. That will help allot.

 

ive been driving with windows down and no a/c cause that smell seems to be coming out of the vents

 

Then it should get better with time. Or just change out the cabin air filter and follow the same steps to make sure it does not get that way again.
