2015-2020 Bentley Bentayga Fender Splash Shield: Part Numbers, Damage, and Replacement
Learn to identify damage, choose the correct used part, and understand the replacement process for your Bentayga's wheel well liners.
- The front fender liners are a multi-piece assembly; verify which section you need before buying.
- Damage is almost always from physical impact. The most common symptom is a scraping noise from the wheel well.
- When buying used, the integrity of the mounting holes is the most important factor to inspect.
- A damaged liner can expose sensitive electronics, like the power steering rack, to water damage.
What is a Fender Splash Shield and Why Does it Matter on a Bentayga?
The fender splash shield, or wheel well liner, is the black plastic or composite liner visible inside the wheel wells of your 2015-2020 Bentley Bentayga. While it may seem like a simple piece of trim, it serves several important functions. Its primary role is to act as a barrier, protecting the expensive and sensitive components behind it—like the engine, suspension, and various electronic modules—from water, salt, mud, and impacts from road debris. It also helps manage airflow for better aerodynamics and significantly reduces road noise from the tires, contributing to the quiet ride expected of a Bentley.
Pro Tip: On the Bentayga, the integrity of the front fender liners is particularly important. A cracked or missing liner can allow water to splash onto the sensitive electronics of the electric power steering rack, potentially leading to costly failures. Maintaining your splash shields is a key preventive measure.
Common Symptoms of a Damaged Fender Splash Shield
Damage to a fender liner is almost always caused by physical impact, such as hitting a curb, a large pothole, or road debris. The symptoms are usually easy to hear or see.
- Scraping or Rubbing Noises: This is the most common sign. A noise coming from a wheel well, especially when turning or going over bumps, usually means the liner is loose and making contact with the tire.
- Flapping Sounds at High Speed: If a section of the liner has come loose from its mounting points, it can flap in the wind at highway speeds, creating a loud and distracting noise.
- Visible Damage: A quick visual inspection can reveal cracks, holes, or sections of the liner that are sagging or dragging on the ground.
- Excessive Debris in Engine Bay: If you notice more dirt, leaves, or water collecting in the engine compartment than usual, it could be a sign that a fender liner is compromised and no longer sealing the wheel well properly.
Known Issues, Recalls, and Service Bulletins
While numerous safety recalls have been issued for the 2015-2020 Bentley Bentayga for issues related to the fuel system, seat belts, and airbags, there are no recalls or Technical Service Bulletins (TSBs) specifically related to the fender splash shields. Failures of this part are due to external damage rather than a manufacturing defect.
Buying a Used 2015-2020 Bentayga Fender Splash Shield: What to Check
Given the high cost of new OEM Bentley parts, a quality used OEM splash shield is an excellent value. However, you must inspect it carefully before buying. Aftermarket options are generally not available or recommended for this vehicle, as fit and material quality may not match the original's noise-dampening properties.
- Inspect All Mounting Points: This is the most critical check. Carefully examine every hole and tab where screws or clips attach. Ensure they are not cracked, broken, or elongated. A shield with damaged mounting points will never fit securely.
- Check for Cracks and Brittleness: Look over the entire surface for cracks or tears. Pay special attention to the edges and any sharp bends. Flex the plastic slightly to ensure it is not brittle from age or sun exposure.
- Verify the Correct Part Number: Bentayga splash shields are side-specific (left/right) and position-specific (front/rear). The front wheel wells use a multi-piece liner, often a forward and a rearward section. Always match the OEM part number from your old part to the used one you are buying.
- Confirm Material Type: Some liners have a felt-like coating for sound absorption. Ensure the used part matches the material of your original part to maintain the vehicle's quiet ride.
Cost of a Replacement Bentayga Fender Splash Shield
Repair costs for a Bentayga are significantly higher than for mainstream vehicles. Choosing a used OEM part can provide substantial savings.
| Part Type | Estimated Cost |
|---|---|
| New OEM | $300 - $500 per section |
| New Aftermarket | Not commonly available |
| Used OEM | $100 - $250 per section |
| Shop Labor | $150 - $250 per side |
Replacement Guide: Difficulty and Basic Steps
Replacing a fender splash shield on a Bentayga is a straightforward job that a DIY mechanic with basic tools can perform.
- Difficulty: 2 out of 5
- Estimated Time: 0.5 - 1 hour per side
- Tools Needed: Jack and jack stands, lug wrench, socket set (for various screws), trim clip removal tool.
Basic Replacement Steps:
- Safely lift the corner of the vehicle and support it with a jack stand.
- Remove the wheel to gain access to the wheel well.
- Identify and remove all fasteners holding the old liner in place. These are typically a combination of screws and plastic push-clips.
- Maneuver the old liner out of the wheel well. If it's a multi-piece liner, you may only need to remove the damaged section.
- Install the new liner, ensuring all mounting holes line up correctly.
- Reinstall all fasteners, but do not overtighten them.
- Reinstall the wheel, lower the vehicle, and torque the lug nuts to the manufacturer's specification.
OEM Part Numbers and Compatibility

Frequently Asked Questions (FAQ)
Can I drive my Bentayga with a broken fender liner?
It is not recommended. A loose liner can rub against the tire and potentially cause a blowout. If it detaches at speed, it can become a dangerous road hazard for other drivers and cause further damage to your own vehicle. It also exposes sensitive components to damaging water and debris.
Is the front fender liner one piece or multiple pieces?
For the 2015-2020 Bentley Bentayga, the front fender liner assembly is typically composed of multiple sections, such as a forward piece and a rearward piece. When ordering a replacement, you must identify which specific section is damaged.
Do I need to paint a replacement fender liner?
No. The fender liners on the Bentayga are made of unpainted black plastic or a composite material. No color matching or painting is necessary.
Why is a used OEM liner better than a new aftermarket one for my Bentayga?
For a precision-built vehicle like a Bentayga, a used OEM part guarantees exact fitment, which is crucial for preventing rattles and ensuring proper alignment. The material composition of an OEM liner is also specifically engineered for noise reduction, a key aspect of the Bentley driving experience that a generic aftermarket part may not replicate.
