OVERVIEW
Genuine VW/Audi Door Reinforcement Bar Bolt
N-911-946-01 is original fastening hardware for specified Audi door reinforcement beam locations. The same OEM part number also appears at assigned radiator support splash deflector positions on selected A6 and S6 applications. The component diagram determines the correct use: the bolt's catalog name does not make it suitable for every door, shield or bracket fastening point.
Technical details
- OEM part number: N-911-946-01 / N91194601.
- Head configuration: Flat-profile head with an internal multipoint drive, identified in the genuine parts catalog and visible in the original photo.
- Primary catalog names: Door reinforcement bar bolt / reinforcement beam screw.
- Additional confirmed function: Front splash deflector screw at specified A6 / S6 mounting positions.
- Supply: One individual bolt. Door reinforcement, door shell, retaining nuts and splash shields are supplied separately.
Common reasons to replace
Replace missing hardware during door component or splash deflector service. Renew a bolt with damaged threads, a bent shank, corrosion or a rounded internal drive that prevents correct tool engagement. Damage beneath the head can also interfere with proper seating. If the original fastener loosened or the retained part has moved, inspect the mating threads, retaining nut and component mounting point before reassembly. Collision damage or a distorted door reinforcement requires assessment of the assembly; new hardware alone does not restore damaged structural parts.
Installation and service notes
Match the original OEM reference to the exact door or splash deflector diagram. Check the mating retainer, align the component and start the bolt by hand without forcing damaged threads. Use a fully seated multipoint tool and follow the vehicle-specific tightening, renewal and thread preparation instructions. A door reinforcement joint and a splash shield joint can have different procedures despite using the same part number, so no universal torque value is implied. Do not replace an adjacent fastener with this bolt merely because the head looks similar.
Vehicle fitment
The table distinguishes the confirmed component locations and vehicle configurations. Match the body style, equipment and installed fastening point. Nearby splash shield bolts can carry different OEM numbers and should be ordered separately when required.
