2016-2022 BMW 750e xDrive Rear Speaker Cover: Rattles and Bowers & Wilkins Fitment
This guide covers the specific rear parcel shelf speaker cover for the Bowers & Wilkins audio system, including common rattle complaints and replacement tips.
- This speaker cover (part #65139365198) ONLY fits 2016-2022 7-Series models with the optional Bowers & Wilkins sound system.
- Rattles from the rear shelf are a common complaint; diagnose carefully to confirm the cover is the cause before starting the repair.
- Replacement is a complex job requiring the removal of the rear seats, C-pillars, and the entire parcel shelf.
- When buying a used cover, the most critical inspection point is ensuring all plastic mounting tabs on the underside are intact.
Symptoms of a Failing Speaker Cover
Failure of this speaker cover is typically related to physical damage or noise. Unlike mechanical parts, it won't trigger any warning lights, but the symptoms can be annoying.
1. Rattling, Buzzing, or Vibrating Noises
The most common complaint related to this part is noise from the rear parcel shelf, especially when playing music with heavy bass. This sound can be caused by several things:
- Loose Speaker Cover: If the mounting tabs are broken or have worked themselves loose, the cover itself can vibrate against the parcel shelf or the speaker housing.
- Blown Speaker: Sometimes, what sounds like a cover rattle is actually a damaged speaker voice coil. You can test this by adjusting the audio balance and fader to isolate the sound to that specific speaker. If the rattle persists only from that channel, the speaker itself may be the issue.
- Sympathetic Vibrations: The powerful speakers of the Bowers & Wilkins system can cause other nearby components to vibrate. Owners have reported rattles coming from license plates or items in the trunk that only become apparent when the stereo is on. Before blaming the cover, remove all loose items from the trunk and check if the noise persists.
2. Physical Damage
As a trim piece, the speaker cover is susceptible to physical damage. Look for:
- Cracks or Fractures: Heavy objects placed on the parcel shelf or improper removal can crack the plastic frame.
- Dented Grille: The metal mesh can be dented, which is a cosmetic issue but can also cause buzzing if the dented portion touches the speaker cone as it moves.
- Sun Fading or Warping: Prolonged exposure to intense sunlight can cause the black finish to fade or, in extreme cases, cause the part to warp, leading to poor fitment and rattles.
- Fuzz Protruding from Holes: Some owners of BMWs with high-end audio systems have noted that the speaker's underlying insulation material can begin to poke through the grille holes over time.
Compatibility Warning: This speaker cover, part number 65139365198, is exclusively for vehicles equipped with the premium Bowers & Wilkins sound system. It will not fit vehicles with the standard HiFi or the Harman Kardon audio systems, as the speaker size and mounting points are different.
Buying a Used Speaker Cover
Given the high cost of a new OEM replacement, a used speaker cover is a great value. However, careful inspection is key to getting a good part.
What to Check Before You Buy:
- Inspect All Mounting Tabs: This is the most critical step. The cover is held in place by several plastic tabs. If even one is broken, the cover will not sit securely and will almost certainly rattle. Ask the seller for clear photos of the underside of the cover to verify all tabs are intact.
- Examine the Grille Mesh: Look for any dents, creases, or tears in the metal speaker grille. A dented grille is not only a cosmetic flaw but can interfere with the speaker itself.
- Check for Cracks and Warping: Inspect the entire plastic frame for hairline cracks, especially around the mounting points. Lay the cover on a flat surface to ensure it is not warped from sun exposure.
- Verify the Part Number: Double-check that you are buying part number 65139365198. A cover from a standard audio system will look similar but will not fit.
Known Issues, TSBs, and Recalls
There are no official recalls or Technical Service Bulletins (TSBs) from BMW specifically for the rear speaker cover on the 2016-2022 750e xDrive. However, there are numerous discussions in owner forums about rattles originating from the rear deck and trunk area in cars with the Bowers & Wilkins system, suggesting it's a common area for noise complaints. These are typically addressed on a case-by-case basis by identifying and isolating the source of the vibration, which may or may not be the speaker cover itself.
Replacement Cost & Difficulty
Replacing the rear parcel shelf speaker cover is a labor-intensive job that requires significant disassembly of the vehicle's rear interior.
Installation Difficulty: 3 out of 5
While not requiring specialized tools, the process is complex and time-consuming. It is feasible for an experienced DIYer, but a novice may find it challenging.
The general steps involve:
- Removing the rear seat bottom cushion.
- Removing the rear seat side bolsters.
- Removing the C-pillar trim panels.
- Disconnecting any wiring for third brake lights or sunshades.
- Removing the retaining clips and lifting the entire parcel shelf out of the car.
- Once the shelf is out, the speaker cover can be unclipped from underneath and replaced.
| Part or Service | Estimated Cost |
|---|---|
| New OEM Speaker Cover | $175 - $215 |
| Used OEM Speaker Cover | $75 - $150 |
| New Aftermarket | Not commonly available |
| Shop Labor Cost | $250 - $450 |
Pro Tip: While the parcel shelf is removed, it's a perfect time to add sound-deadening material to the metal deck underneath. This can help reduce vibrations and rattles from the powerful B&W subwoofers, providing a noticeable improvement in sound quality and reducing noise complaints.
Frequently Asked Questions (FAQ)
Will this speaker cover fit my 7-Series if I don't have the Bowers & Wilkins system?
No. This cover is specifically designed for the speakers and mounting points of the B&W system. It is not interchangeable with the covers from the standard or Harman Kardon systems.
A rattle is coming from my rear shelf. Is it definitely the speaker cover?
Not necessarily. The powerful bass from the B&W system can cause many things to vibrate. Before replacing the cover, empty your trunk, check your license plate for tightness, and try to isolate the noise to determine if it's the cover, the speaker itself, or another trim piece.
How difficult is it to replace this cover myself?
It is moderately difficult. You must remove the rear seats and several large interior trim panels to access and remove the parcel shelf. This can take 2-3 hours for someone with experience. A novice DIYer should review videos of the procedure for similar BMW models before starting.
Can I just glue a cracked speaker cover?
While you can attempt to repair a small crack with plastic epoxy, it is often a temporary fix. The vibrations from the speaker will likely cause the crack to reappear or start a new rattle. For a permanent solution, replacement is recommended.
