Moisture in headlights

[GD]

I have really bad condensation in my n/s headlight.  is there a drain or is the seal gone (never been bumped) and back to the dealer?

Seems to be common across all sorts of cars.  BMW will change it if it is particularly bad - though what qualifies as 'really bad' is probably open to the Dealer's interpretation, day of the month, age, sex, religion, tanning level, clothes worn, last bollocking for over supporting customers etc etc etc....... >:(

Thanks.  It is bad, water was running down and I am good at complaining.

That sounds like it needs changing.  Small amounts of condensation are OK and should 'burn off' once the lights are on.
