- Blocked intake system
- Faulty air flow sensor
Was Sie tun können
- 1Check that the air filter is not clogged
- 2With the ignition off, check the plugs at the control module and at the air flow sensor for poor contact, resistance and oxidation

- 4If the fault returns although the wiring and connectors are sound, have a workshop replace the air flow sensor
