Got the same warning today. I'm DC and it's been unusually cold as well. I've been sending pics of random issues like this to firstname.lastname@example.org
. If u send email documenting the issue and attach pic they will open up a trouble ticket and keep it on file. They will also notify your dealership so when you bring your car in you won't show them what the problem is. I've sent a few things in. I plan on dropping off car next week to address all my issues With respect this issue, I'm not sure if it's a one off thing since it's super cold although Audi builds for winter climate.
