- condensation fog lights
I used a heat gun to warm up the light when I had this issue, and once it dried out, I never saw it happen again.
Mine started after swapping over to LED's

Foggy light
led's seem to be the problem because you don't get the warmth
I've currently got condensation in my indicator lens

have you thought about a couple of silica gel sachets to suck up the moisture ???
assuming the lamp housing is not cracked and bulb seal are not leaking . . . . . .
just a thought . . .

Can you access the inside of a DRL? I thought they were a sealed unit.
Just the packet... so you can retrieve it at a later date.... or when its saturated and needs replacing.
Cheers @Dellmassive il dry it out again and see can i get a better seal/fit on the bulb and put a silica packet in. Would putting vaseline on the rubber seal on the bulb give it a better seal do you think?.
Yeh maybe, just a small amount.
Foggs.....not DRL
My bad. I could of sworn one of the Manchester meet guys had a DRL issue. I need to stop filling my head with useless VW stuff
After switching from halogen to LED, condensation in the fog lamps is generally caused by the design flaw in the LED cooling fan.
LED bulbs are not IP rated and not actually internally sealed. I suppose it is manufacturer's intension to allow some air flow (forced by the fan) to cool down the internal part of the LED "bulb".
Fan constantly "pumps" ambient air to the inside of the fog lamp. This air is pulled from the area close to the road, not to mention driving in wet conditions.
Example of my old fog LED bulbs.
The air gaps between the "inside" and the "outside" can be seen below.
My solution (or improvement) to the problem is reversing the polarity of the supply to the fan.
In some cases desoldering & swap over of 2 wires is required(fan blades don't work in the most efficient way, but still work), in some other cases there is a possibility to physically rotate the fan and reverse the air flow.
By changing the direction of the air flow the air is constantly sucked out of the fog lamp, so is any condensation.
