OVERVIEW

Genuine VW/Audi M8 timing belt tensioner nut, part number N-011-008-45. This threaded fastener secures the belt tensioner to its mounting stud on the specified 2.0T FSI engines. Correct seating and tightening retain the tensioner in its intended position while the timing belt synchronizes crankshaft and camshaft movement.

Technical details

  • Original part number: N-011-008-45 / N01100845.
  • M8 nominal thread size; internally threaded hex nut.
  • Supplied individually. Tensioner, mounting stud, belt and rollers are separate.
  • Listed applications use the BPY timing-belt FSI engine. Chain-driven TSI engines require their own timing components.
  • Match the factory nut assignment, stud and tensioner arrangement; nominal thread size alone does not establish interchangeability.

Common reasons to replace

Replace a missing nut, damaged threads, rounded hex faces or corrosion that prevents reliable engagement and seating. This nut is also relevant when renewing the associated hardware during timing belt and tensioner service. Inspect the stud and tensioner mounting surface at the same time.

A loose tensioner, belt tracking problem or abnormal timing-drive noise requires inspection of the complete belt drive. A new nut cannot correct a worn tensioner bearing, damaged stud, misaligned roller or incorrect belt adjustment.

Installation and service notes

Follow the factory timing procedure for the exact engine and VIN. Maintain the prescribed crankshaft and camshaft positions, inspect the stud threads, and start the nut by hand. Adjust the tensioner and tighten its hardware in the specified sequence to the assembly-specific torque.

After assembly, carry out the prescribed manual rotation and recheck timing alignment and tension before starting the engine. Observe factory renewal requirements for all adjoining hardware. Do not substitute a generic M8 nut solely because it threads onto the stud.
