Hva betyr feilkoden?

The long-term correction on bank 2 has reached its lower limit. This means the engine control module has cut the fuel quantity as far as it can, because the mixture on bank 2 has been too rich.

Mulige årsaker

Fuel pressure is too high
The injectors leak fuel
The mass air flow sensor is defective
The oil is contaminated
The oil level is set too high

Hva du kan gjøre
