OVERVIEW
Genuine engine attachment hardware
The N-910-098-01 Genuine VW/Audi collared bolt is used at the original engine attachment points specified in the fitment table. On the listed Volkswagen 2.5L applications it secures the front crankshaft sealing-flange connection. The specified Audi TT and TTS applications use this factory number at the assigned engine coolant inlet-pipe mounting connection.
These are separate mounting applications using the same fastener number. Match the vehicle row and original attachment point rather than treating the bolt as a universal engine fastener. It is not an engine-mount support bolt, oil drain plug or coolant sealing ring.
Technical details
- Complete factory number: N-910-098-01.
- Nominal factory specification: M6 × 12.
- Design: internally driven collared mounting bolt.
- Volkswagen application: assigned front crankshaft sealing-flange hardware on the listed 2.5L engines.
- Audi application: assigned coolant inlet-pipe/tube attachment on the listed TT and TTS configurations.
- Unit supplied: one bolt.
The nominal size describes the threaded fastener specification rather than its shipping package. Correct replacement also depends on the collar, head seating arrangement and original joint. Do not substitute another M6 bolt solely because it starts in the receiver.
Common reasons to replace
- A bolt is missing following sealing-flange or coolant-pipe service.
- The internal drive is damaged or rounded.
- The threads are crossed, stripped or otherwise damaged.
- The head or collar no longer seats correctly.
- The original fastener was damaged during removal or replaced with incorrect hardware.
Inspect the flange or pipe mounting point and the threaded receiver before assembly. A new bolt cannot repair a cracked flange, damaged pipe bracket or stripped thread. Oil and coolant leaks require inspection of the appropriate seals and mating components; this bolt does not supply a replacement seal.
Vehicle fitment
The table distinguishes sealing-flange hardware from coolant-pipe hardware. Retain the stated engine and body requirements. For the complete Volkswagen front-flange connection, the catalog identifies ten bolts; this listing supplies one.

Installation guidance
Follow the factory procedure for the exact flange or pipe connection. Apply all prescribed preparation, sealing, alignment and replacement-hardware instructions for that joint. Do not transfer a tightening value from a different application merely because the fastener number is shared.
Align the component before starting the bolt, engage the threads carefully and use the correct tool for the actual drive profile. Tighten in the required sequence and to the specified instruction for the vehicle and connection. Do not use the bolt to pull a damaged or misaligned component into position.
After service, restore disturbed components and perform the specified operating and leak checks for the repaired system.
Ordering information
