In a method and device for monitoring an exhaust gas recirculation system of an internal combustion engine, an actual value (AV_EGR) of an exhaust gas recirculation rate is determined depending on a load degree (LD) of a soot particle filter (21) for filtering particles out of an exhaust gas of the internal combustion engine and/or depending on a soot content of the exhaust gas. The actual value (AV_EGR) of the exhaust gas recirculation rate so obtained is compared with a predetermined setpoint value (SP_EGR) of the exhaust gas recirculation rate. The exhaust gas recirculation system is monitored depending on the comparison of the actual value (AV_EGR) of the exhaust gas recirculation rate and the predetermined setpoint value (SP_EGR) of the exhaust gas recirculation rate.
