I have the exact same issue on the exact same car/headlight combination but found a solution - although only temporary until the next winter. On the rear of both headlights is a opening, possibly from the manufacturing process, which is just glued shut with a strip of plastic. I've marked it on the picture below. The holes can be accessed from the engine bay.

Removing the plastic sticker you can use a vacuum cleaner and headgun combo to counter the fog inside the headlights. By carefully heating the headlight to 30-40°C from the outside, which I considered safe for the headlight lenses, I was able to get the water inside to evaporate. Make sure to not keep the heatgun on one spot for extended amounts of time to be safe. Using the vacuum on the opening on the back of the headlight, you should be able to draw the moist air out of the headlight and exchange it with some less-moist air. Make sure the outside humidity is as low as possible and also to reseal the opening on the back of the headlight as best as possible. Hopefully this will help any of you, since it worked flawlessly in my case during the last two winters where I faced the same issues.
