OVERVIEW
Specified fastener for the engine oil level sensor
N-911-279-02 is the Genuine VW/Audi M6x25 bolt cataloged for the engine oil level sensor mounting positions below. Correct hardware helps secure the sensor flange evenly at its assigned engine location.
Fasteners with a similar diameter can have different lengths, head forms and clamping requirements. Match the original factory number and assigned joint rather than choosing a bolt by appearance alone.
Technical details
- Complete factory number: N-911-279-02.
- Factory specification: M6 × 25 oil level sensor fastening bolt.
- Design: recessed drive head with collar and threaded shank.
- Quantity supplied: one individual bolt.
The nominal thread and length describe the fastener itself. This listing supplies one bolt rather than the full quantity required for an assembly. Matching nuts, washers, brackets and related parts are separate.
Common reasons to replace
- The original bolt is missing after component service.
- Threads are damaged or will not engage correctly.
- The drive head is rounded or otherwise damaged.
- Corrosion or deformation makes the original fastener unsuitable for reuse.
Inspect the sensor flange, sealing surface and mating threads. This listing supplies hardware only: a sensor fault or leak may require separate sensor, seal or mounting-surface repair.
