Abstract

A method for monitoring a fuel supply system in an internal combustion engine includes the steps of: recording a first pressure value in the fuel supply system in a region of the fuel supply system associated with a pre-filter and upstream of a low pressure pump; recording a second pressure value in the fuel supply system downstream of the low pressure pump in a region of the fuel supply system associated with a primary filter; monitoring the first pressure value and the second pressure value for an error state of the fuel supply system; and recognizing the error state only if the error state is plausible on a basis of both the first pressure value and the second pressure value.
