Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order.

Suggestion
Might be worth checking the vents, when I had a similar problem with my E36 M3 the trick was simply to remove one of the covers from the back of the headlight which sorted the condensation very quickly.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Model 04 turbo tiptronic I have condensation (and pooling) in one headlamp. It blew the indicator bulb ( i guess it was this) and caused a) fast flashing if remaining n/s indicators and intermittently b) stem to not function in either direction (hazards work). In trying to research it seems there are two very different views on how these units work and hoe to solve this How they work: School 1 - they are sealed School 2- they are vented How to prevent future moisture (after getting them dry): School a - find break in seals..and silicone glue them up/fix broken bulb fittings School b - find the vents and clear them School c - drill little holes to allow escape Can anyone give a definitive answer and if it they are vented...can anyone tell me where to look for blockages as i cant for the life of me see them?? Thanks K

So from the other thread it looks like the headlights are vented (makes sense I guess, they must get very hot in summer/very cold in winter and if they were sealed they would likely pop a seal). Might be worth checking the vents, when I had a similar problem with my E36 M3 the trick was simply to remove one of the covers from the back of the headlight which sorted the condensation very quickly. I noticed you can get these vents: https://www.retrofitlab.com/en/breathing-vents-2.html from retrofit labs which look a bit neater and might sort the problem out.

My take on this issue .. If you have a slight misting in the middle of winter then i would argue its condensation .. If you have "pools " of water inside then that sound to me like a leak . When i'm looking for water leaks on a car i pour water on it and visually look for where its coming into the car .. yup it's that basic i'm afraid .. Nothing to stop you doing the same on the headlight .
