Hello gang. I have a 2008 Touareg II, and I've not been driving much recently,(close to things so I walk a lot). Anyhow, the last few times I've driven, I can hear an audible sloshing around sound of what I'm assuming is water coming from my passenger side... I've swung around the doors to see if I can replicate the sound or find where it's trapped, but nothing! Any hints here?! It's gonna freeze soon, and I don't want standing water sitting in the truck. Thanks in advance for any advice!
