Abstract
In a method for performing diagnostics on line systems, in particular crank casing venting systems of internal combustion engines, a correction value for an operating parameter of the internal combustion engine is formed in each of at least two chronologically successive determining steps. The correction values or values which are derived therefrom are used to detect a faulty state of the line system.
