LEFT Door Mirror Glass ASPHERICAL: OE reference Part No 971857521D
L0L / 5SL / 6XT / 6XW

PR:L0L = Left-hand drive version
PR:5SL = Door mirror, Left, ASPHERICAL
PR:6XT = Door mirror, automatically dimmable, electrically rectractable/adjustable, separately heated + memory
PR:6XW = Door mirror, automatically dimmable, electrically rectractable/adjustable, separately heated
The aspherical mirror glass provides a wide field of view from the left exterior door mirror while helping reduce blind spots. The dimmable function helps reduce glare from headlights behind the vehicle, improving visibility and comfort during night driving.

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. Replacing the mirror glass restores clear side visibility, improves driving safety, and returns the mirror assembly to the correct OE-style specification.
When to replace
• The mirror glass is cracked, broken, scratched, or missing
• The dimming function no longer works correctly
• The mirror surface has dark patches, stains, or internal fluid marks
• The reflective surface is cloudy, faded, or delaminating
• 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 or restored to original specification
Where it fits on the car
