2014-2020 BMW i8 Fender Moulding: Fitment, Part Numbers, and Replacement Guide
This guide covers the common failure points, part numbers, and critical compatibility differences for the BMW i8's unique fender mouldings.
- The most critical factor is compatibility: this part is for the BMW i8 Coupe ONLY and will not fit the Roadster model.
- When buying a used moulding, the most important thing to inspect is the condition of the plastic mounting tabs on the back; broken tabs will prevent a secure fit.
- Replacement is a simple DIY task, requiring only plastic trim removal tools to prevent scratching the paint.
- There are no known recalls or TSBs for this specific part, and failures are purely cosmetic or related to physical damage.
Symptoms of a Failing Fender Moulding
Since the fender moulding is a passive cosmetic part, symptoms of failure are entirely visual or physical. There are no associated dashboard warning lights or fault codes.
- Visible Damage: Scuffs, scratches, and cracks are the most common issues, usually resulting from minor impacts, parking lot scrapes, or road debris.
- Loose Fit or Rattling: The moulding is secured by a series of plastic clips and tabs. Over time, these clips can become brittle and break, causing the moulding to feel loose, vibrate, or rattle at speed.
- Fading or Discoloration: Prolonged exposure to UV rays from the sun can cause the plastic or painted finish to fade, creating a mismatched appearance with the rest of the bodywork.
- Complete Detachment: In severe cases where most mounting clips have failed, the moulding can detach from the vehicle entirely, especially when driving at highway speeds.
Warning: A loose fender moulding should be secured or removed immediately. If it detaches at speed, it can become a dangerous road hazard for other drivers.
Known Issues, TSBs, and Recalls
As of mid-2026, there are no specific recalls or Technical Service Bulletins (TSBs) issued by BMW or the NHTSA that directly address the fender mouldings on the 2014-2020 BMW i8. Recalls for the i8 have focused on issues like the high-voltage battery system, fuel tank, and electronic stability control. While forum discussions and owner complaints mention various minor issues, widespread failure of the fender moulding is not a commonly reported problem.

The single most important factor when sourcing this part is the body style. The fender mouldings for the BMW i8 Coupe are NOT compatible with the i8 Roadster (convertible) model. The body panels and trim pieces differ between the two versions. You must ensure the part you are purchasing is explicitly for the Coupe model.
Buying a Used 2014-2020 BMW i8 Fender Moulding
Buying a used OEM fender moulding is an excellent way to save money, as aftermarket options are virtually nonexistent for this specialized part. A used OEM part guarantees the precise fitment required for the i8's tight panel gaps. Pay close attention to the following when inspecting a used part:
- Inspect All Mounting Tabs: This is the most critical inspection point. Carefully check the back of the moulding for any broken, cracked, or stressed plastic mounting tabs. Even one broken tab can prevent the moulding from sitting flush and securely.
- Verify the Part Number: Always match the part number to ensure you are buying for the correct side (left or right) and model (Coupe). The part number provided in your vehicle's data, 7352685, corresponds to the rear left pillar grille/trim for the Coupe.
- Check for Cracks and Warping: Examine the entire piece for any hairline cracks, especially around the mounting points. Hold it up and sight down its length to ensure it is not warped or bent, which could indicate it was removed from a wrecked vehicle.
- Assess Cosmetic Condition: Expect minor scuffs or light scratches on a used part. Deep gouges or significant paint damage will require refinishing, so factor that potential cost into your purchase decision.
Pro Tip: Purchase from a reputable automotive recycler that provides clear, high-resolution photos of both the front and, most importantly, the back of the part so you can verify the condition of all mounting points before you buy.

Replacement Overview
Replacing a fender moulding is generally a straightforward task suitable for a DIYer with the right tools. The process involves carefully prying the old moulding away from the body to release the clips.
Tools Required:
- Plastic Trim Removal Tool Kit
- Microfiber Towel
The basic procedure involves using plastic pry tools to gently release the retaining clips holding the old moulding in place. It is crucial to use plastic tools and work carefully to avoid scratching the vehicle's paint or clear coat. 🎬 See this DIY side trim installation walkthrough Once the old part is removed, the new moulding is aligned and pressed firmly into place until the clips snap in. No special programming or calibration is required.
Frequently Asked Questions (FAQ)
Will a fender moulding from an i8 Roadster fit my i8 Coupe?
No. The body panels and trim pieces are different between the Coupe and Roadster models. You must purchase a part that is specifically listed for the i8 Coupe.
Do I need special tools to replace a fender moulding?
It is highly recommended to use a plastic trim removal tool set. 🎬 Watch: How to install side skirts and trim Using metal tools like a screwdriver will almost certainly scratch or damage the paint and surrounding body panels.
Does the used moulding come painted?
A used OEM moulding will come in the original color of the vehicle it was removed from. You will need to find one that matches your car's color or have it professionally repainted.
Can I repair a cracked fender moulding?
While very minor scuffs can be polished or painted, a cracked moulding cannot be reliably repaired. A crack compromises the structural integrity of the part and its mounting points, meaning it should be replaced.
