Drove down to Florida from New Jersey, and a few days after arriving I noticed my 2016 Passat has severe condensation in the drivers side headlamp. In the morning I noticed that it was minor, went for a 30 minute drive in the afternoon (87 degrees and sunny), and when I arrived at my destination, it was no longer minor, but drips of water all over the inside. I did replace the bulbs a couple of months ago and remember having a hard time getting the back seal for the bulb on correctly. I just sealed the cap correctly, but the condensation continues to be okay in the morning but really bad during the middle of the day and into the night. Any suggestions? Do I need to look into replacing the headlamp? 1st pic is of morning before drive, 2nd pic or after arriving at my destination.

Probably have a leak somewhere make sure the covers at the back are on properly. Water must be getting in somewhere

Now that I look a little closer, the rubber lining in between the headlamp and bumper looks worn down and I do see a gap where potential water is going into the headlamp. Do you recommend I use some kind of silicone to patch it up, or will that make it difficult if I ever need to remove the headlamp.

My B6 had the same issue with the driversside headlight . The problem is a not fully functional drain tube on the backside of the headlight.

A solution is to remove the rubber caps as if you were to replace a bulb. And then blow hot air in it for about 10-15 minutes. (I used my wife’s hairdryer for this) After this, let is sit for an hour or so. Then put back the rubber caps.

It does require a warm and sunny day for it to have the best effect.

Hmm, with the tropical weather down here, I'm afraid it'll happen again within a day or two. I'm going to see if me properly putting the cap on helps at all, If not, I'll remove it and dry it out when its not raining.
