Why Replace This Part?
Door mirror glass can become cracked, scratched, cloudy or damaged from impact, road debris, weather exposure or cleaning wear. Dimmable mirror glass can also fail internally, causing dark patches, stains, liquid marks or reduced visibility. If the mirror glass includes lane change assist functionality, damage or incorrect replacement glass may also affect the visibility of the side assist warning indicator. Replacing the glass with a Genuine Porsche OE aspherical dimmable mirror glass helps restore the correct field of view, factory appearance and original mirror functions, including lane change assist compatibility where fitted.
When to Replace This Part
• If the left mirror glass is cracked or broken
• If the glass is scratched, cloudy or discoloured
• If the auto-dimming function has failed
• If the mirror has dark patches, staining or liquid marks
• If the lane change assist indicator area is damaged or no longer visible
• If mirror heating is no longer functioning due to glass failure
• If visibility through the mirror is poor
• After impact damage to the exterior mirror
• During mirror housing repair or replacement
• When restoring the car with correct Porsche OE parts.
Where It Fits on the Car
This mirror glass fits in the left-hand exterior door mirror assembly. For left-hand-drive vehicles, this is normally the driver-side mirror. It installs into the mirror carrier inside the door mirror housing and connects to the relevant heating, dimming and lane change assist connections where fitted.
