2020-2022 BMW 750e xDrive Rear Vanity Mirror: A Guide to the Headliner-Mounted Luxury Feature
This guide focuses on the often-overlooked rear overhead vanity mirrors, covering common failure points, inspection tips for used parts, and replacement.
- This guide is for the REAR overhead vanity mirrors, not the front sun visors.
- The most common failure is the integrated LED light, which requires replacing the entire unit.
- When buying used, verify the part number (e.g., 51447424501), check for physical damage, and ensure the color matches your headliner.
- Replacement is a very easy DIY job, requiring only a trim tool and taking less than 15 minutes.
Symptoms of a Failing Rear Vanity Mirror
Failures of the rear vanity mirror are typically straightforward to diagnose and are usually related to the light, the physical assembly, or the mirror itself. Because it is not a critical component, there are no associated OBD-II codes.
1. Light Does Not Turn On
The most common symptom is when the light fails to illuminate when the mirror cover is opened. The light source is an integrated LED module, not a simple replaceable bulb. The failure could be due to a burned-out LED, a faulty switch in the cover's hinge mechanism, a loose electrical connector, or a problem with the wiring in the headliner.
2. Physical Damage
The mirror assembly is made of plastic and can be damaged. Look for cracks in the housing, a broken or loose-fitting cover flap, or a cover that will not stay closed. The mirror glass itself can also be cracked from an impact or show signs of delamination (a bubbling or peeling look) over time, similar to how auto-dimming mirrors can fail.
3. Rattling Noises
A rattling sound from the headliner area near the mirror can indicate that the assembly's mounting clips have broken or that the unit has become loose in its housing. This can happen after a hard impact or during removal and reinstallation.
Pro Tip: The light activation switch is built into the hinge of the mirror cover. Before assuming the LED has failed, gently wiggle the cover while it's open to see if the light flickers. If it does, the switch is the likely culprit, and the entire unit will need to be replaced.
Buying a Used Rear Vanity Mirror: What to Check
Purchasing a used OEM rear vanity mirror is a cost-effective solution, as new units can be surprisingly expensive. However, careful inspection is key to getting a good part.
Key Inspection Points:
- Verify the Part Number: The primary OEM part number is 51447424501. However, other numbers like 51447422096 may be used for specific colors like Black. Always match the part number from your old unit or confirm fitment with the seller using your vehicle's VIN.
- Inspect the Mirror Glass: Check seller photos carefully for any scratches, scuffs, or cracks. Look for any signs of delamination or discoloration around the edges.
- Test the Cover/Hinge: Ask the seller if the cover opens and closes smoothly and if it clicks shut securely. A loose or broken hinge means the light may not function correctly.
- Examine the Housing and Clips: Look for any cracks in the plastic housing. Crucially, ensure all mounting clips on the back of the unit are intact. If these are broken, the mirror will not sit securely in the headliner.
- Check the Electrical Connector: The pins inside the electrical connector should be straight and free of any corrosion or damage.
- Match the Color: These mirrors come in different colors like Black and White (sometimes called 'Alcantara White') to match the vehicle's headliner. Ensure the color of the used part matches your car's interior.
Known Issues, TSBs, and Recalls
As of this writing, there are no specific recalls or Technical Service Bulletins (TSBs) issued by BMW or the NHTSA for the rear overhead vanity mirrors on the 2020-2022 BMW 750e xDrive. This is a non-critical interior component with a low failure rate, so widespread issues are not expected.
Replacement Difficulty: 1/5
Replacing the rear vanity mirror is a simple DIY task that can be completed in minutes.
- Pry Out the Old Unit: Using a plastic trim removal tool to avoid damaging the headliner, carefully pry around the edge of the mirror assembly. It is held in by pressure clips.
- Disconnect the Wiring: Once loose, pull the unit down slightly. Depress the tab on the electrical connector and pull it to disconnect the wiring harness.
- Install the New Unit: Connect the wiring harness to the new mirror assembly. You should hear it click into place.
- Test the Light: Before pushing the unit back into the headliner, open the cover to ensure the light works.
- Secure the New Mirror: Align the new assembly with the opening in the headliner and press it firmly into place until the clips engage and it sits flush.
Warning: While not strictly necessary for a simple component like this, it is always best practice to disconnect the vehicle's battery before working on any part of the electrical system.
Cost Comparison
The price difference between new and used OEM parts is significant, making a used part an excellent value.
| Part Type | Estimated Cost |
|---|---|
| New OEM | $180 - $250 |
| Used OEM | $10 - $50 |
| New Aftermarket | Not commonly available |
| Shop Labor | $50 - $100 (typically less than 0.5 hours of labor) |
Frequently Asked Questions (FAQ)
Can I just replace the bulb in the vanity mirror?
No. The illumination is provided by an integrated LED module. If the light fails, the entire vanity mirror assembly must be replaced.
Is this the same as the mirror in the front sun visor?
No. This guide is for the separate vanity mirrors mounted in the rear headliner for back-seat passengers. The front mirrors are part of the sun visor assemblies and use different part numbers.
Does a replacement rear vanity mirror need to be coded or programmed?
No. This is a simple plug-and-play component. As long as you have the correct part for your vehicle, no programming is required.
My mirror light stays on all the time. What's the cause?
This is likely due to a failed switch in the mirror's cover hinge. The switch is stuck in the 'on' position. The entire unit will need to be replaced to fix the issue.
