Dear all,I have just collected my 525i sport from AB last night. It was raining during my collection. When I reached home I found both the head lamp with some mist stain on them. Call AB and they say there is a ventilation hole for the xenon light hence created the stain after rain, it will goes off after a short while. Eventually, during my collection time there is another 523i having the same problem as mine. Do anyone having the same problem as mine?regards
