Noticed this only recently , a band of condensation at the   bottom of the headlamp glass, obviously goes away as the headlamp unit warms but is this a common problem or should it me attended to

I had this and posted it here before. I was told "normal" by the dealer. Surprisingly, mine has gotten a lot better with a lot less condensation over the past year......

As above, this is normal behaviour and mine also seems to have got better with the passing of time. It's only a problem if it doesn't go away once the headlamp is warmed up or if the condensation becomes particularly heavy.
