OVERVIEW
Genuine timing-chain assembly fastener
The N-106-609-02 Genuine VW/Audi bolt is assigned to the original timing-chain assembly on the engine configurations listed below. Its M10×40 factory specification and internal multipoint drive identify a specific service fastener.
Timing assemblies contain several bolts that differ in length, head design and application. Match the complete factory part number and original position. This individual bolt does not include a chain, guide, tensioner, sprocket or a complete timing hardware set.
Technical details
- Complete factory number: N-106-609-02.
- Factory specification: M10 × 40.
- Design: socket-head bolt with internal multipoint drive.
- Quantity supplied: one individual bolt.
The nominal thread diameter and catalog length help identify the hardware; they do not establish interchangeability with another M10 bolt. Use the original engine-specific service position and factory tightening procedure.
Common reasons to replace
- The original drive recess is damaged and no longer accepts the correct tool securely.
- The threads are damaged or contaminated beyond the permitted repair procedure.
- The bolt is missing during timing-system assembly.
- The original bolt has corrosion or other physical damage.
- The applicable factory repair procedure requires new hardware at the serviced position.
Inspect the mating threads and retained component before installation. A replacement bolt cannot correct worn chains, damaged guides or timing faults. Diagnose timing-related symptoms separately and replace other components only as required by the repair findings.
Vehicle fitment

Installation guidance
Follow the factory engine-specific timing repair procedure, including the prescribed locking, support and counterholding methods. Use the correctly fitting multipoint tool, prepare the threads as directed and tighten to the specification for the original attachment.
Complete the required timing alignment and mechanical checks before starting the engine. Refit disturbed covers and seals using the specified procedures. Do not borrow torque or angle values from neighboring timing bolts.
Ordering information
Supplied as one genuine bolt. A full timing service requires other hardware and components according to the vehicle-specific repair plan. Verify the required quantity and original position before ordering.
