OVERVIEW
Genuine glass sliding-sunroof frame hardware
The N-907-498-02 Genuine VW/Audi bolt secures the assigned original sunroof-frame mounting connection on the vehicles listed below. It is an individual replacement for the factory fastener, with an oval head and internal drive as shown in the archive photograph.
The sunroof frame relies on its correct mounting hardware and alignment. This bolt is specific to its cataloged position rather than a replacement for every screw in the roof assembly. Vehicles must have the original compatible glass sliding sunroof; roof equipment and body configuration remain part of the fitment check.
Technical details
- Complete factory part number: N-907-498-02.
- Nominal factory specification: M6 × 12.
- Design: oval-head internally driven mounting bolt.
- Application: assigned glass sliding-sunroof frame attachment.
- Unit supplied: one bolt.
The nominal size describes the threaded fastener specification rather than a packaged shipping measurement. Match the complete number, head seating arrangement and mounting location. A bolt of the same thread diameter but a different length or head profile may not suit the original frame connection.
Common reasons to replace
- A bolt is missing following sunroof-frame or headliner service.
- The internal drive is damaged or rounded.
- The threads are crossed, stripped or otherwise damaged.
- The head or bearing surface no longer seats correctly.
- An incorrect substitute was previously installed.
Inspect the frame mounting point and threaded receiver before fitting replacement hardware. A new bolt cannot repair a cracked frame, damaged receiver or distorted roof mounting point. Roof alignment, drainage and operating faults require diagnosis of their relevant components rather than assuming replacement hardware will resolve them.

Installation guidance
Follow the factory sunroof-frame removal, alignment and installation procedure for the exact model. Support the frame as prescribed and protect the headliner and surrounding trim. Keep the original hardware positions identified during disassembly.
Align the frame before starting the bolt, engage the threads carefully and apply the specified tightening sequence and instruction for that connection. Use the correct tool for the bolt's actual drive profile. Do not use the fastener to pull a misaligned or damaged frame into place.
After assembly, perform the prescribed roof adjustment and operating checks, confirm mounting retention and restore all covers, trim and drain connections disturbed by the repair.
