OVERVIEW
Genuine bolt for the original steering-column coupling
The N-105-184-04 Genuine VW/Audi bolt secures the assigned steering-column coupling attachment on the configurations below. Its M8×30 specification and internal multipoint drive distinguish it from the shorter column-support bolts.
The steering-column assembly uses separate fasteners for its supports, adjustment mechanism and shaft connection. Match this exact factory number and original location. This is one coupling bolt rather than a steering column, universal joint or complete hardware set.
Technical details
- Complete factory number: N-105-184-04.
- Factory specification: M8 × 30.
- Design: socket-head bolt with internal multipoint drive.
- Quantity supplied: one individual bolt.
The correct thread engagement and original coupling geometry are essential to the attachment. A nearby M8 bolt with a different length or head style is not interchangeable merely because it can enter the thread.
Common reasons to replace
- The original coupling bolt is missing during steering repair.
- The internal multipoint recess is damaged.
- Threads are damaged or cross-threaded.
- The bolt has physical damage.
- The applicable factory procedure requires a replacement bolt after the connection is released.
Inspect the shaft coupling, mating surfaces and receiving threads according to the factory procedure. A new bolt cannot correct wear in the universal joint, damaged splines or a distorted coupling.

Installation guidance
Follow the factory steering-column coupling repair procedure, including the prescribed column restraint, wheel alignment and restraint-system precautions for the access required. Align the shaft connection exactly as directed and use the correct multipoint tool and tightening specification.
Complete the specified connection, steering operation and diagnostic checks before returning the vehicle to use. Do not transfer a tightening specification from a column-support bolt or another M8 fastener.
Ordering information
