Hi Guys

I have noticed eveer since I got my E34 that the rear screen takes a long time to demist - probably over 15 mins maybe more. I can see one or two elements look broken, but I thought all the others should clear fast enough.

Could it be an extra fault like starting on the reduced power setting rather than cutting down once the rear screen has been on a while? Thoughts anyone? Are rear screen demisters usually better than this?

TIA for contributions, all suggestions gratefully received.
