E39 sport headlamp condensation.

[wezzer-45's]

Hi Guys,

I've recently bought myself an e39 528i sport which I'm really enjoying.
I have an issue of condensation in the o/s headlamp.
Apparently this is quite a common issue on the e39's. Has anyone got a fix for this issue after drying them out with a hair dryer?
The car is a 2000 model and so doesn't have the angel eye lamps. Does the lense come off and seals changed or are they sealed units.

Any help or avice would be appreciated.

I tried the hair dryer technique and it seemed to clear the fogging but left the droplets there.
The next morning it was worse than ever, the lamp was completely covered and looked terrible.

Today I removed the lamp which was very easy to do, and stripped it down to access the lense. I popped out the lamp glasses and properly dried out the lamp.
I don't know if it will help but I also applied rainex to the inside of the lense.

The job only took 25 mins in total and I think the origional cause was the indicator bulb holder wasn't clipped in properly.
Fingers crossed it is now sorted.
