On my R231 from 2012 the windshield was replaced last week because of rockfall. On today’s first trip, the wind noises from 120 km/h seemed quite loud to me. Then I looked at the new disc a little bit more closely and found a 6 mm wide and about 5 mm deep air gap at the top, between the disc and the frame. I am not sure if it was already available before, or if there is a gasket or the part of a gasket missing now. . I will drive to the workshop again on Monday, but it would certainly be good if I didn’t stand there so stupid. Maybe someone can help me by looking at his R231. Thank you in advance. Hinnerk
