[quote=""X5Sport""]Have you got auto dimming mirrors? If so it looks like the electro-chromic layer has failed. If it is 'leaking' then it is the electro-chromic fluid that changes colour when a voltage is applied. If not then the tint layer has failed but that would not flow. Probably a new mirror glass of the right type required. It's an odd colour though. It almost looks as if two parts of the mirror have parted company, hence the 'leak'.[/quote]
That's right mate, if I Push the mirror with my fingers I can see the liquid moveing around,

you really know your stuff
Hmmm maybe I will try separating the two layers so that I can clean the mirror properly
Thank you for the estimate Raj but there is no way I am spending £200 or more on a mirror that still works as a mirror
