Hi all, I've been searching for this issue for weeks! Our VW Atlas smells awful since we've been turning the AC back in June! It's horrible the smell of stall water mildew stays inside the cabin and even from outside the vehicle. My dealer doesn't know what to do about this ! I'm so glad it's not just my atlas with this problem. I have sprayed a full can of AC cleaner inside all the ventilation trap and it still smells awful. My dealer told me to contact my car insurance and I did but they refused because troubleshooting is not part of a coverage car insurance, in other words, go back to your dealer. Now we are stuck with an Atlas that smell bad. I will contact my dealer again and if this doesn't get resolved I will call VW Canada to make a legit complain about this issue. I will keep you posted ! thanks for the therapy lol
