A method for the operation of a particulate filter in an exhaust aftertreatment system of a combustion engine () with the following steps: set up () a pressure difference model, which models a measured pressure difference (&#x394;p) which drops across the particulate filter () as a function () of a volume flow ({dot over (V)}) through the particulate filter () with an offset value (a, C); measure () multiple measurement values () for the pressure difference (&#x394;p) at different volume flows ({dot over (V)}) and solve () the pressure difference model as a function of the pressure difference (&#x394;p), whereby the offset value (a, C) is also determined.
