Hoping someone can answer this.....
I have the auto-dimming rear view mirror (think it was standard on the GTI?). Anyway, the driver's side dorr mirror also seems to be auto-dimming as it tends to go slightly green when driving at night with someone behind me and also it seems to have a visible film covering the glass, apart from the 1-2mm around the edge.
However, the passenger side doesn't seem to dim or have the film. Is this right or should it be the same as the driver's side? I just wonder if the car has had a new mirror glass at some point and they have put a normal one on by mistake.
Cheers.
