My service adviser just told me that Porsche designed the TT to have self dimming mirrors only on the driver side and in the middle, but not on the passenger side.

I checked it, and it seems to be true. Is it the same on your car? Why would Porsche designed it that way?

 

It's standard, driver side and rear view.

 

same ^_^...dunno why... but on my mercedes it's like that too...
