OVERVIEW
Genuine VW/Audi Starter Mounting Bolt
N-909-564-02 is an original M10 x 45 mm bolt used at specified starter motor mounting positions. The correct fastener helps retain the starter at its designed mounting joint so the assembly remains properly seated. Starter hardware varies with engine, transmission and mounting position; use the exact OEM number rather than choosing a bolt by vehicle model or appearance alone.
Technical details
- OEM number: N-909-564-02 / N90956402.
- Nominal size: M10 x 45 mm.
- Head: External hex head with an integral collar and internal Allen drive.
- Application: Assigned starter retaining positions; selected diagrams distinguish this bolt from shorter starter bolts and solenoid hardware.
- Supply: One individual bolt. The original photograph illustrates more than one bolt; this listing does not supply a pair or a complete starter hardware set.
Common reasons to replace
Replace a missing bolt during starter replacement or related transmission service. Damaged threads, corrosion, a bent shank, rounded drive surfaces or damage beneath the collar can interfere with engagement and correct seating. If a starter has become loose, inspect the mounting flange and receiving threads before fitting new hardware. A damaged mounting point must be repaired as required; a new bolt alone will not correct worn threads, a cracked flange or an electrical starting-system fault.
Installation and service notes
Confirm the M10 x 45 position in the original starter diagram and compare the removed hardware. Follow the vehicle's electrical isolation procedure before starter work, support the assembly and align the mounting faces before starting the bolt by hand. Use the vehicle-specific tightening sequence, torque and renewal instructions. Do not substitute a generic M10 torque value, and do not interchange this fastener with an adjacent M10 x 40 bolt or a starter-solenoid screw merely because the heads appear similar.
Vehicle fitment
Each application below requires the starter fastening position that explicitly calls for N90956402. The GTI entry is limited to the confirmed 6-speed DSG configuration. Other rows require a match to the vehicle's installed starter and transmission diagram.
