my 2016 audi a6 3.0 vibrates in sub zero temperatures at 70 mph. this lasts for avout an hour then goes away. it only happened in sub zero temperatures. however the last two noreasters we had with heavy snow caused it to happen again. only at 70mph or above for approx 1 hour then stopped. i have the 19 inch tires that came with the car, pressure 36 psi all around. wheels are balanced and all 4 wheels are properly alligned. dealer checked the car and said everything is ok. they never heard of anything like this before. i cant figure out what is causing this. its driving me crazy.

You have any snow/ice frozen inside any of the rims? It's easy to miss and overlook. .02

+1. I have had same experience and indeed was snow/ice frozen inside the wheels. As soon as outside temp went above freezing and car was sitting in sun for the day no more wheel imbalance. Not just an Audi thing -- have had it also on wife's Volvo and my daily driver Acura TL. I too have the 19s on the A6 -- big/wide wheels with lots of area for snow/ice to freeze and hide. Hopefully something as simple as this is your issue.

Best,
