Was bedeutet der Fehlercode?
The electric brake vacuum pump helps the brake booster build up vacuum. The code is set when the pressure does not fall far enough within a certain time while the engine is running. The fault may lie in a leak, the relay, the pump or the non-return valve.
Mögliche Ursachen
- Leak in the vacuum system
- Damaged relay
- Damaged pump
- Damaged non-return valve
Was Sie tun können
- 1Check that the hoses between the vacuum system and the brake booster are intact and firmly fitted, since a leak causes this fault
- 2Listen for hissing from hoses and connections while the engine runs
- 3Check the non-return valve in the vacuum system so that it does not let air through
- 4If you have a diagnostic tool: activate the vacuum pump and check that it runs
- 5If the brake pedal feels heavier than usual, do not keep driving; have a workshop fix the fault
- 6If the fault returns, have a workshop check the relay and the pump
Symptome, die Sie bemerken können2
- Yellow warning symbol and text message in the display
- Brake pedal requires more effort than normal
