OVERVIEW
Genuine VW/Audi N-107-446-01 is an individual hexagon collar nut assigned to the original starter assembly fastening point shown in the verified Tiguan catalogs below.
Technical details and contents
The photographed part has a hexagonal wrenching body and integrated collar. This listing supplies one nut; the starter motor, studs, bolts, terminals and wiring are separate. Match the exact factory number and original connection rather than selecting solely by appearance.
Factory number: N-107-446-01 / N10744601. Brand: Genuine VW/Audi. Quantity supplied: one individual fastener.
Function and application
The collar provides the specified bearing face at its assigned connection. Starter diagrams also show mounting bolts, link bolts and electrical contacts with different functions. This nut is not a substitute for those components, and its catalog position must be matched before installation.
Common reasons to replace
- The original nut is missing after starter removal.
- The internal threads are stripped, crossed or otherwise damaged.
- Rounded wrenching flats prevent controlled removal or tightening.
- The collar or seating face is distorted or badly corroded.
- Incorrect replacement hardware was fitted during an earlier repair.
Vehicle fitment
Use the complete vehicle, engine and component-point information in this table. Confirm the factory assignment against the original hardware and vehicle identification before ordering. The same vehicle can contain several similar-looking fasteners with different specifications.
| Vehicle | Model years | Engine | Configuration | Application restrictions |
|---|---|---|---|---|
| Volkswagen Tiguan | 2018–2024 | 2.0L turbocharged gasoline inline-four | Second-generation long-wheelbase SUV; original starter nut point 5; 8-speed automatic; front-wheel drive / 4Motion | Assigned starter collar nut at original diagram point 5. Confirm the installed starter and stud connection; excludes first-generation Tiguan Limited. |
Installation guidance
Follow the factory starter service procedure, including electrical isolation before working around the starter supply connections. Inspect the mating stud and seating face. Start the nut by hand to protect the threads, use the correct tool and tighten only to the specification for the exact connection. Do not transfer a starter mounting-bolt torque to a nut at another point. A replacement nut alone does not diagnose a slow-cranking or no-start concern.
Retain all application-specific workshop instructions, including hardware renewal requirements and the correct tightening sequence. Check that the mating components are properly supported and aligned before tightening. The fastener must seat correctly without compensating for damaged or misaligned parts.
Ordering information
This is one genuine replacement starter collar nut, not an assembly or hardware kit. Related components, seals, washers and other fasteners are supplied separately. Check the required quantity for the exact repair before ordering.
