摘要：
In a method for operating an internal combustion engine having a compressor, the diagnosing of a clutch of the compressor is achieved without an additional sensor system. The compressor is turned on via the clutch, and a variable characterizing the air-mass flow to the internal combustion engine is ascertained. A first value of the variable characterizing the air mass flow before turning on the compressor is compared to a second value of the variable characterizing the air mass flow after turning on the compressor by closing the clutch, and an error is detected as a function of a deviation between the first value and the second value of the variable characterizing the air mass flow.
