I have the problem of steaming up camera wing mirrors. The offside after 3 months of buying my Audi Etron QUATTRO 55. Then both of them 6 months after that all visits under warranty on a 2020 model.
I live on the Isle of Lewis so cannot just pop in to the nearest Audi dealer.
Today the nearside steamed up again so I carefully removed the bezel and very carefully prized the class screen. I say VERY carefully!! The glass/clear poly carbonate did not break and wiped off all the moisture with a camera lens cleaning cloth. Back to perfect vision then started to mist up a couple of hours later.
Very poor design so when there is some really sunny hot weather I will do the same again and let it breath. I am tempted to put a some silica gel bag in the housing and get to the bottom of why moisture is getting in there.
This should not happen on a car that is an expensive luxury car..
