Lights mist over
E39, E53
Situation:
One or more of the vehicles lights mist over. On modern plastic lens covers, this misting
over can occur in unfavorable circumstances and does not necessarily constitute a defect.
Unfavorable climatic conditions, e.g. a rapid drop in temperature with high air humidity
(storm showers, car wash, underground car park), may result in more or less major streaks
on the lights. Because of the geometrical design of the lights, there is uniform air
distribution inside the light housing. Humid air brought in through the ventilation system
thus reaches the cold areas of the lens cover relatively quickly and then causes misting.
These traces of humidity are purely an optical defect that do not affect the light output or
distribution, as the lens cover does not have any technical function in the lighting. After
operating the light for some time (up to 15 minutes, depending on weather conditions and
driving profile), the misting will disperse through the ventilation openings provided.
Affected vehicles:
E39 and E53 with plastic lens covers.
Action:
In case of customer complaint, explain the situation to the customer as described above.
If the light should still be misted over after a lengthy operating period, or if drops of water
larger than 1 mm diameter are formed, the headlight may be leaking.
Known quality matters are explained in the relevant enclosure.
