My E90 only about 3 weeks young. This morning was waiting at a car park lot with the sun in front of me. Notice that there were dust on the windscreen. But lo and behold, the windscreen is pitted. very small and hard to see unless there is a reflection. COunted about 4 pitts. Any one with new E90 encounter the same thing. usual travel route is Alexandra and town. Din remember driving next to a sand lorry.
