OVERVIEW
Factory collar nut for the manual-transmission mounting joint
N-107-175-01 is the Genuine VW/Audi M16 x 1.5 hexagon collar nut used at the assigned transmission mount connection on the listed Audi R8 manual-transmission applications.
The collar provides the original bearing face against the mounting stack. The mounting hardware differs between manual and S tronic transmissions, so identify the exact gearbox and part number before ordering.
Technical details
- Complete factory number: N-107-175-01.
- Factory specification: M16 x 1.5.
- Design: external hexagon collar nut with integral bearing flange.
- Quantity supplied: one individual nut.
M16 identifies the nominal thread diameter and 1.5 mm the pitch. The listing supplies one nut; left and right mounting positions may require more than one. Mounts, distance plates and bolts are separate components.
Common reasons to replace
- The nut is missing after transmission or mounting service.
- Threads are damaged or crossed.
- The hexagon is rounded or damaged.
- The bearing flange no longer seats correctly.
- Incorrect hardware was installed at the original connection.
Inspect the mounting bolt, distance plate, support and rubber mount. Correct damaged threads or worn mounting components before tightening. A new nut alone does not repair drivetrain movement caused by a failed mount.
Vehicle fitment
The confirmed application requires the six-speed manual transmission and PR G0X. Match the assigned mounting position.

Installation guidance
Support the transmission as specified and follow the exact mounting procedure. Assemble the original distance plate and mount arrangement, start the nut by hand and tighten to the prescribed specification. Renew hardware wherever the procedure requires it.
Verify support seating, clearances and secure mounting before removing support. Complete the required operating checks after the repair.
