This system for assisting the maintenance of a particle filter integrated into an exhaust line of a motor vehicle diesel engine is characterized in that it comprises means ( 1 ) for calculating the volume of ash from the engine lubricating oil, means ( 2 ) for calculating the volume of ash from the engine fuel, means ( 4 ) for calculating the usable volume (V.u) of the particle filter from a total volume of said filter when new (V.new) and the previously calculated volumes of ash, and means ( 5 ) for calculating a degree of clogging of the particle filter (d.c.) from the total volume of the filter when new (V.new) and the previously calculated usable volume (V.u) to trigger a maintenance request (Maint. Req.) if the degree of clogging (d.c.) exceeds a predetermined threshold (threshold).
