Why Replace This Part?
Door mirror glass can become cracked, chipped, scratched, cloudy, loose, or delaminated over time. Dimmable mirror glass can also fail internally, causing dark patches, stains, liquid marks, or loss of dimming performance. If the mirror glass is damaged or the lane change assist display area is affected, visibility and driver assistance function may be reduced. Replacing the mirror glass restores clear side visibility, OE-style appearance, and correct mirror equipment compatibility.

•  The dimming function no longer works correctly
•  The lane change assist display area is damaged or unclear
•  The mirror surface has dark patches, stains, or internal fluid marks
•  Visibility from the left mirror is poor or distorted
•  The glass has become loose or detached from the backing plate
•  The door mirror has been damaged by accident or parking impact
•  The vehicle is being repaired to original mirror specification.

Where it fits on the car
This mirror glass fits in the left-hand exterior door mirror assembly on left-hand drive Porsche 9YA Cayenne and 95C Macan-e models. It mounts into the original mirror housing and connects to the mirror electrical system where dimming and lane change assist equipment is fitted.
