Many of us have been waiting to replace brownish auto-dimming rearview side mirrors for a long while now, as described in this post by Tim. The problem has concerned both 9-3 and 9-5 owners.
Recently this issue has been solved. According to Viktor Karlsson, Product Marketing Manager / Global Marketing at Orio, auto-dimming rearview side mirrors are now available on all markets. It is a long term solution with secured supply over time.
A MY10 mirror glass (pos11) is combined with a frame (pos5) and a cover (pos10). Parts information has been sent to all retailers. A new mirror will work fine with an older one, if you only need to replace one.
The drawback with this solution is that you need to get the new cover painted.
