Restore the visibility and sophisticated tech-integration of your Bentley with this Genuine OEM Left-Hand Side Mirror Assembly. This specific combination of part numbers represents a high-specification mirror unit, typically featuring integrated heating, auto-dimming, and power-folding capabilities.

Component Breakdown

• Mirror Housing / Power Unit (36A857507A): The internal motorized skeleton. This includes the power-folding motor, the glass adjustment actuators, and the wiring harness.

• Mirror Glass (36B857539): The premium, aspherical glass lens. This unit is typically equipped with an internal heating element and an electrochromic layer for automatic dimming.

Technical Features

• Auto-Dimming (Electrochromic): Automatically tints the glass to reduce glare from trailing vehicles at night.

• Integrated Turn Signal: Features the high-intensity LED indicator strip.

• Memory Function: Fully compatible with Bentley’s seat/mirror memory positions.

• Puddle Lamp: Includes the downward-facing LED that illuminates the ground with the Bentley “B” or logo.

• Side Assist / Blind Spot Monitor: Depending on the specific suffix, this unit supports the internal LED warning light for vehicles in your blind spot.

Signs of Failure

• Motor “Grinding” or Failure: The mirror fails to fold or unfold, or makes a clicking sound when trying to move.

• Glass Discoloration: A “liquid” look or gold/brown tinting on the edges of the glass indicates the auto-dimming fluid has leaked internally.

• Heating Failure: The mirror stays fogged or iced over in cold weather despite the rear defroster being active.

Installation & Fitment Note

Color Matching: The exterior mirror cap (cover) is generally sold separately or transferred from your original unit. If your mirror cap is damaged, you will need to provide your paint code (e.g., Beluga Black, Glacier White) to order a replacement.

VIN Verification Required

Bentley mirrors have over 20 different internal wiring configurations based on options like 360° Cameras, Blind Spot Assist, and Night Vision. To ensure 36A857507A and 36B857539 match your vehicle’s specific build:

1. Check for Camera: Does your mirror have a camera lens on the bottom?

2. Check for Blind Spot Warning: Is there a car icon etched into the glass?

3. Provide your VIN: We will verify the pin-count on the connector to ensure “Plug & Play” compatibility.
