Why Replace This Part?
Door mirror glass can become cracked, scratched, cloudy or damaged from impact, road debris, cleaning wear or weather exposure. Poor mirror visibility can affect safety and driver confidence, especially when changing lanes, parking or checking surrounding traffic. Replacing damaged mirror glass with a Genuine Porsche OE flat mirror glass restores clear visibility, correct Porsche fitment and the original exterior mirror appearance. It is important to use the correct version for cars without Lane Change Assist / LY0, as mirror glass variants differ depending on vehicle equipment.

When to Replace This Part
  If the left mirror glass is cracked or broken
  If the glass is scratched, cloudy or discoloured
  If visibility through the mirror is poor
  After impact damage to the exterior mirror
  During door mirror housing repair or replacement
  When replacing incorrect mirror glass on a car without Lane Change Assist
  When restoring the vehicle with correct OE Porsche 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 replaces the original mirror glass only.
