Headlight Condensation

Good idea Chris also the cold weather will cause the rubber to contract a little which could affect the effectiveness of the seal, either gently heat them if you don't have a nice warm garage.
 
thanks chris going to change mine try to get the condensation out hope it works
 
Evening all

I have this issue with my z4 2005, what’s the best solution that isn’t going to take up too much time and cost that much?

I was thinking of replacing the light, but the condensation looks like it’s there to stay. Should I change the whole headlamp which is very costly?
 
Buy new rear headlight covers from BMW. £16 including the seal. Do both sides.
Remove old covers. Drive out all the moisture with a hair dryer. Allow to cool before fitting new covers. Job done.
 
I had this problem with my first Zed. As suggested, new rear light covers, but also recommend before fitting them, wait for a warm sunny day, remove the old ones and take the car for a drive, then leave parked up facing the sun for an hour or two, before fitting the new rear covers.
 
I wouldn’t advise heating the lens like the video. Easy to burn the plastic - like he did. I’d recommend removing the bumper and properly drying them inside the house next to a radiator or in hot water tank cupboard if you have one. New headlight cover (with good rubber seal) will prevent water getting in again.

Agreed. Only shared to show how to remove the panel as it was all I could find on YouTube. As mentioned before, if you weren't going bumper-off, then I'd personally leave the rear light panels off on a hot day and let nature do its thing which worked for me. Not a hairdryer or heatgun in sight :!:
 
I agree on the sunny day option but such a thing is hard to come by at the moment! A hairdryer on a low heat setting will do the trick without excessively heating the light lenses (which you really want to avoid).
I propped the hair-dryer in the wheel arch and let it run for 20 minutes or more.
Whichever method you use, you must allow the air in the headlamp to return to ambient temperature before putting the cover on the back.
Otherwise you risk more condensation as the air inside the headlight cools down
