My aeromax had the same issue

I was told by one of the continetal main agent that it couldn t be fixed

I was in Italy this week and Luigi Borghi, the Italian dealer fixed it.

No more annoying noise, even if it is not 100% quiet

However, the two rear opening glasses went bang one after another. Apparently, the glue originally used can t cope with any temperature above the British summer and need to be replaced by something stronger...
