Method for diagnosing low-pressure exhaust-gas recirculation of internal combustion engine, involves judging difference between determined low pressure exhaust gas reconducting mass flow and estimated value during deviation of error signal

The method involves measuring fresh air mass flow (15) in an air mass sensor (18). Mass flow (72) flowing by a compressor (22) is determined. Difference between sum mass flow and the fresh air mass flow is determined. Low pressure exhaust gas reconducting mass flow (71) is determined. Estimated valu...
