OVERVIEW
Original upper steering-column mounting hardware
N-911-542-01 is the Genuine VW/Audi M8 x 75 bolt assigned to the specified upper steering-column mounting point. The long shank and head bearing arrangement match the original support joint rather than a general body attachment.
The upper mounting bolt, lower column bolt and intermediate-shaft fastening bolt are separate parts. Select the complete factory number for the actual joint being serviced, even when several bolts appear together in a steering-column diagram.
Technical details
- Complete factory number: N-911-542-01.
- Factory specification: M8 x 75 mm steering-column upper mounting bolt.
- Design: Long shank, recessed drive and head bearing flange for the assigned column support.
- Quantity supplied: one individual bolt.
M8 x 75 is the confirmed nominal size. Correct full part number, drive engagement and mounting position are required; a general-purpose M8 fastener is not selected by length alone.
Common reasons to replace
- A damaged drive recess that prevents controlled tightening or removal.
- Damaged threads, a bent shank or an impaired head seating surface.
- Missing original mounting hardware or an incorrect substitute found during column service.
Column looseness, vibration or noise can arise from a worn bracket, damaged support or adjustment mechanism fault. Inspect the complete mounting assembly and receiving threads before replacing hardware.
