Water in headlight assembly

So after having baked my headlights several months ago to install some DDEs, the drivers side randomly got water in it yesterday after washing the car. It may just be the glue that was used is not sealing it properly and if so where can I pick some up. I prefer not to use silicone and would rather stick with the OEM glue used.

However, if it is the glue not sealing properly, why did it just happen randomly after all this time and why is the passenger side assembly fine?

My thoughts are just to rebake but I have a feeling if it is the glue and I rebake I will have the same problem unless I add another method of protection.

I was able to get most of the condensation out by using a hair dryer but I dont really feel like having this problem every time it rains (not sure if it will even happen if it rains).

Any help would be great b/c I would rather not have to go into the whole ordeal of baking the lights again.

Sounds like your going to have to rebake and reseal your lights. I dont think it just happened randomly. Did you run the car through the carwash before this problem? Those carwashes are pretty powerful. If you dont have a good seal, that water pressure will shot water right into the housing. Ask the dealer to see if they have the OEM glue. Otherwise, you can go get the liquid gasket stuff from Autozone or someplace like that.

Thanks for your post.
I removed the headlight assembly and let it air out. No more water (it was just a light amount on the len) and used a hair dryer to make sure it was completely dry. I inspected the seal and it looks solid and holds against water. The only thing I can think of now is that the other day on the highway I hit a plastic bag going about 90 and didnt think to much of it but it hit my headlight. There is a tiny tiny scratch about where the water seemed to be concentrated but I cannot tell if this scratch goes all the way through the headlight or is just on the outside surface. I really hope it it not all the way through. If it is I may just dab a small amount of clear sealant on it
Its not too big of a deal now b/c the fix I can do without baking my lights now.

Anyone have experience with a chip going all the way through their lens?
TIA

Do you have to bake the headlights to get the lens off? I was trying to get the lens off to install my angel eyes the other night and couldn't yank it off. Is there a guide on how to do this with the 3 series 04's and on?

You only have to bake the headlights on facelifted coupes. Other models are held together in a different manner.
