Abstract: Various embodiments include a method for operating a fuel evaporation retention system of a vehicle with an internal combustion engine. It includes measuring a pressure change resulting from a temperature change of a gas volume in the fuel tank over a defined period of time while the vehicle is at a standstill after the engine controller has been switched off and comparing an expected pressure profile based on a given temperature profile based at least in part on the tank fill level and after the engine controller has been switched on to an actual measured pressure profile from a previous vehicle standstill phase. If the measured pressure profile lies within a settable tolerance around the expected pressure profile, the method confirms a leak-tight fuel tank. If the measured pressure profile lies outside the settable tolerance, the method identifies a faulty fuel tank and displaying an alert.
