OVERVIEW

Factory screw-adjusted clamp for the pressure hose

N-909-502-01 is the Genuine VW/Audi 40–60 x 9 mm clamp used at the assigned charge-air pressure hose connections below. Its screw-adjusted metal band secures the original hose over its matching fitting.

Turbocharged plumbing can contain several clamp types and diameters. Identify the exact hose connection and original number before selecting this part; the model or engine alone does not make every clamp interchangeable.

Technical details

  • Complete factory number: N-909-502-01.
  • Factory specification: 40–60 x 9 mm.
  • Design: slotted metal band with screw adjustment housing.
  • Quantity supplied: one individual clamp.

The factory designation identifies a 40–60 mm clamping range and a 9 mm band width. The adjustment range must suit the original hose and fitting, and the clamp must occupy the prescribed location.

Common reasons to replace

  • The adjustment mechanism is stripped and no longer holds the band securely.
  • The band or housing is damaged or distorted.
  • Corrosion prevents controlled adjustment.
  • The clamp is missing after pressure hose or turbocharger service.
  • Incorrect hardware was installed at the original connection.

Inspect the hose for splits, softening, damaged ends and oil-related deterioration. Check the fitting and sealing area as well. A new clamp cannot repair a split pressure hose or broken connector, and a boost leak requires diagnosis of the complete connection.

Vehicle fitment

Confirm the specific pressure-hose position listed below and match the original factory number.

Installation guidance

Allow the engine to cool and follow the vehicle-specific pressure hose procedure. Fully seat the hose, position the band correctly and tighten to the prescribed requirement. Avoid cutting the hose or deforming the fitting through excessive tightening.

Check routing and clearance, then perform the required charge-air leak and operating checks after assembly. Replace damaged hoses and fittings separately.

Ordering information
