⚙️ Key Features

  • Locking filler-cap design supplied with the applicable key arrangement
  • Approximately 60 mm filler-neck configuration
  • Designed for diesel exhaust fluid and AdBlue/urea tank service
  • Protects the tank against dirt, water and accidental contamination
  • Must match the filler-neck thread or bayonet profile and the aftertreatment installation
  • Do not substitute a fuel or coolant cap for an AdBlue filler cap
  • Also supersedes Volvo part number 22836562

🔌 Function

Seals and protects the AdBlue tank filling point while allowing authorised filling and service access.

⚠️ Common Signs of Failure

  • The cap no longer locks or releases correctly
  • The seal is cracked, hardened or missing
  • AdBlue crystals or leakage form around the filler neck
  • Dirt or water enters the tank
  • The cap or key is lost, cracked or mechanically damaged

🛠️ Service Notes

  • Fit the cap specified for that filler on your engine — caps that look alike differ in seal, venting and pressure rating, and a substitute may hold the system at the wrong pressure or not seal at all
  • Wipe the filler neck and check its sealing land for nicks, corrosion and distortion before fitting; many apparent cap leaks are actually neck leaks
  • Check the cap's seal is soft and unbroken, and that any vent or breather hole through the cap is clear
  • Seat the cap fully, to its stop or lock position — a cap left part-turned will weep, and on a pressurised system can lift
  • Never open a cap on a hot pressurised system; let it cool first
