Abstract
A fuel filter, in particular diesel fuel filter (), of an internal combustion engine, in particular of a motor vehicle, and a heating sensor module () are described. A filter housing () has at least one inlet for the fuel to be cleaned and at least one outlet () for the cleaned fuel. A filter element () is arranged in the inner chamber () of the filter housing () in such a manner that it separates the at least one inlet from the at least one outlet (). At least one heating unit () for heating the fuel, at least one temperature sensor () for detecting a temperature of the fuel and at least one water level sensor () for detecting a water level of water separated from the fuel in a water collection chamber () are integrated in the heating sensor module (). At least one heating element () of the heating unit () is arranged in a heating chamber () which, with respect to a fuel flow (), is located outside the inner chamber () of the filter housing () between the inlet () and an unfiltered side of the filter element (), and which, at the same time, is bounded by a module housing () of the heating sensor module ().
