OVERVIEW
Genuine VW/Audi N-906-575-02 is an individual clamping washer for the original trunk and luggage-compartment trim attachments identified below. The formed center engages the intended retaining post, while the outer bearing surface retains the trim at its assigned point.
Technical details and contents
- Factory number: N-906-575-02 / N90657502.
- Component type: push-on clamping or retaining washer.
- Formed center gripping features and circular outer bearing surface.
- Quantity supplied: one individual washer.
- Trim panels, retaining posts and other clips are separate.
This retainer performs a different function from an ordinary loose flat washer. Match the original post and trim arrangement rather than selecting a washer only by its outside appearance. The archive photograph shows the individual item supplied.
Function in the trim assembly
The washer retains the assigned trim component on its original mounting post. Its formed center provides the intended engagement at that point. Correct retention helps keep the trim seated without relying on an unrelated screw or improvised hardware.
The same catalog number appears in several trim diagrams. The table identifies the verified mounting areas and body styles individually. Trunk-lid trim, luggage-compartment trim and rear package-tray arrangements must be matched to the actual vehicle.
Common reasons to replace
- The retaining washer is missing after trim removal.
- The center gripping features were distorted during removal.
- The washer is bent or cracked.
- The retainer no longer holds securely on the original post.
- Corrosion or damage prevents correct seating.
Inspect the trim and mounting post before installing a new retainer. A replacement washer cannot repair a broken post, torn mounting area or distorted trim panel. Do not force an incorrect retainer onto a post with a different profile.

Installation guidance
Follow the factory trim removal and installation procedure for the exact vehicle. Protect nearby finish surfaces and support the panel while releasing its retainers. Identify the original order and location of clips and washers before reassembly.
Align the trim and retaining post before installing the washer. Seat the retainer evenly with the appropriate tool and avoid distorting its center gripping features. Do not hammer an unsupported panel or overdrive the washer to compensate for damaged trim.
After assembly, check that the panel is seated correctly and that adjacent wiring, handles and access points remain unobstructed. If a rattle remains, inspect the other retainers and mounting areas rather than forcing this washer farther onto the post.
