LEFT Door Mirror Glass ASPHERICAL: OE reference Part No 9Y1857521N
L0L / 5SL / 6XT / 6XW
CODES:
PR:L0L = Left-hand drive version
PR:5SL = Door mirror, Left, ASPHERICAL
PR:6XT = Door mirror, automatically dimmable, electrically retractable/adjustable, separately heated + memory
PR:6XW = Door mirror, automatically dimmable, electrically retractable/adjustable, separately heated
The aspherical mirror glass provides a wider rear-side field of view from the left exterior mirror, helping reduce blind spots and improve side visibility. The dimmable function helps reduce glare from headlights behind the vehicle, while the lane change assist compatibility supports the vehicle’s side monitoring system where fitted.
Functions
• Replaces the left-side exterior door mirror glass
• Provides aspherical wide-angle side visibility
• Helps reduce blind spots on the left side of the vehicle
• Supports dimming function to reduce glare during night driving
• Compatible with lane change assist mirror specification
• Fits into the original Porsche door mirror housing
• OE Match replacement for damaged or failed original mirror glass.
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.
When to Replace This Part
• The mirror glass is cracked, broken, scratched, or missing
• 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.
