Abstract
A method is described for monitoring an exhaust aftertreatment system of a combustion engine, with a pressure difference sensor that captures a first pressure difference between a first sampling point and a second sampling point. A second pressure difference between the second sampling point and the environment is captured. A defect is detected based on the second pressure difference.
