Abstract: The invention relates to a method for operating a particulate filter (3) taking the ash loading into consideration, to an arrangement in this respect, to a control unit in this respect, and to a vehicle in this respect, wherein, during the operation of the internal combustion engine (1), fuel and/or lubricants are at least partially converted into ash by the internal combustion engine (1), wherein a first ash value is calculated on the basis of the fuel consumption and/or the lubricant consumption of the internal combustion engine (1), wherein, after regeneration of the particulate filter, the differential pressure across the particulate filter (3) is determined, wherein a second ash value is calculated on the basis of the determined differential pressure, wherein the ash quantity in the particulate filter (3) is determined from the first and the second ash value, and wherein, if the determined ash quantity exceeds a predefined value, a status device is activated.

Abstract: The invention relates in particular to a method for adjusting the loading (19) of a particulate filter (9) and to an assembly designed to carry out the method, wherein the exhaust gas aftertreatment unit (8) comprises at least two SCR systems (11, 12) and a particulate filter (9), a first operating material amount being introduced in a metered manner before the first SCR system (11), and a second operating material amount being introduced in a metered manner before the second SCR system (12), the operating material being convertible into a reducing agent.
