Yes it would be interesting to establish a few facts on the screens in an attempt to "crack" the problem - doubtless the factory have their own answer which involves them spending money. We won't be likely to hear that one then.
The first question to ask is is it only heated screens that are susceptible and the next has the supplier changed and so forth.
Interesting hearing your story though.
Not as interesting as your "new" Red Roadster though - enjoy woohoo
