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
