Are you getting Fords to look at them? Could the current cold / damp spell be having an effect on the condensation? I've noticed our house windows are misting up on the outside of the glass this past week which is most unusual
The car will be inspected on Monday and I will insist the parts in question are replaced. To date they have been very helpful. They are replacing a rear high stop lamp because it has an almost invisible 2mm long scratch near a fixing screw.
The internal misting should not occur in a sealed unit unless the seal is damaged. It may be a manufacturing fault in a particular batch but needs to be remedied or it will cause corrosion.
As for the 'damaged' headlight lens, I think somebody had a dirty glove when it was fitted and smeared something white on the lens. That must be removed or the lens replaced. However, I think the whole headlamp housing may be replaced as I cannot see them taking it apart to fit a lens.
The 'damage' can only be seen when the dipped beam is on and you look carefully at the lens as I did when judging where to fit beam deflectors.
I would hope everyone will post their faults so we can all check our cars for similar faults.
