  • Listed for 12 applications across MB, MD and AQD series engines

🔌 Function

Moves in its bore against a spring to regulate oil pressure or flow, opening a passage once the set pressure is reached.

⚠️ Common Signs of Failure

  • Oil pressure high, low or unstable
  • Piston sticking in its bore, giving pressure that jumps around
  • Piston or bore scored, varnished or gummed with debris
  • Pressure warning coming on at idle when hot

🛠️ Service Notes

  • Clean the bore thoroughly and check the piston falls freely under its own weight before assembly
  • Renew the spring if it is collapsed or corroded, since a tired spring gives the same symptoms as a worn piston

📦 Condition

  • Genuine Volvo Penta part
  • Brand new
  • Supplied in original or equivalent packaging
