OVERVIEW
Genuine vacuum-reservoir attachment screw
The N-105-453-02 Genuine VW/Audi panel screw secures the assigned original vacuum-reservoir mounting connection on the S6 application listed below. The factory specification includes a 4.2 × 55 screw and flocked finish at the head.
The vacuum-reservoir assembly also uses separate retainer hardware, insert nuts and other screws. Match this complete number to the assigned receiving point instead of selecting hardware only by the reservoir or engine appearance.
Technical details
- Complete factory number: N-105-453-02.
- Factory specification: 4.2 × 55; flocked.
- Design: socket-head panel screw with the original flocked-head finish.
- Quantity supplied: one individual screw.
The nominal size identifies the screw itself rather than packaged shipping dimensions. Match the original receiving insert and seating arrangement. This panel screw is not interchangeable with a machine-thread bolt or the separate 5 × 24 fastener shown in the same assembly.
Common reasons to replace
- The original screw is missing after reservoir or bracket removal.
- The drive head or screw threads are damaged.
- The screw has bent and will not align or seat correctly.
- The specified head finish is damaged during previous service.
- An incorrect substitute screw was installed previously.
Inspect the reservoir, retaining bracket and receiving insert before fitting the screw. A new fastener cannot repair a cracked reservoir, damaged mount or stripped insert. Vacuum leaks and engine faults require diagnosis of the complete system.
Vehicle fitment
The row requires the original TV7 4.0L gasoline V8 vacuum-reservoir arrangement. Six-cylinder engines and other reservoir connections require separate confirmation.

Installation guidance
Follow the factory vacuum-reservoir access and installation procedure. Keep hoses and connections identified, align the reservoir and retainer without strain and engage the correct receiving insert carefully. Use the actual drive tool and prescribed tightening instruction for the attachment.
Confirm the reservoir is supported correctly and the screw head seats without distorting the mount. Restore all hoses and retainers disturbed during access, verify routing and perform the prescribed vacuum-system checks.
