17887/ P1479/005241 - Brake Boost Vacuum System: Mechanical Failure

Possible Causes

  • Fuse(s) faulty
    • if the blade wheel (rotor) in the vacuum pump is stuck, most probably a fuse will burn
  • Hoses from/to Brake Boost Vacuum Pump faulty
  • Brake Boost Vacuum Pump faulty
    • the blade wheel (rotor) in the vacuum pump is stuck

Possible Solutions

  • Check / replace fuses
    • check if the blade wheel (rotor) of the vacuum pump is stuck, otherwise the fuse will burn again
  • Check Hoses from/to Brake Boost Vacuum Pump
  • Check Brake Boost Vacuum Pump
    • check if blade wheel (rotor) is stuck
    • Perform Output Test
    • Perform Short Trip
