Workshop diagnostic system for facilitating the search for faults on a technical object, in particular on a motor vehicle, comprising: at least one diagnostic tester and at least one diagnosis server, wherein the diagnostic tester has at least one object communication apparatus, which is designed to receive first diagnostic data from at least one object control unit of the technical object, and at least one transmission unit, which is designed to transmit the first diagnostic data to the diagnosis server; wherein the diagnostic tester and/or the diagnosis server are designed to use the first diagnostic data to form at least one set of first diagnostic data that comprises at least some of the first diagnostic data and to associate at least one first diagnostic result with the set of first diagnostic data, a first database designed to store first diagnostic datasets (181, 182) created in the course of successive diagnoses, wherein each of the first diagnostic datasets (181, 182) comprises a respective set of first diagnostic data and the at least one first diagnostic result associated with the set of first diagnostic data, a second database designed to store predefined second diagnostic datasets (201, 202), wherein each of the second diagnostic datasets (201, 202) comprises a respective set of second diagnostic data and a second diagnostic result associated with the set of second diagnostic data, characterized in that the workshop diagnostic system further comprises an evaluation system, having an association unit designed to compare the diagnostic data and/or the diagnostic result of a respective one of the first diagnostic datasets (181, 182) with the diagnostic data and/or the diagnostic result of the predefined second diagnostic datasets (201, 202), and to associate with the respective first diagnostic dataset (181, 182) one of the predefined second diagnostic datasets (201, 202) that has the greatest similarity to the respective first diagnostic dataset (181, 182) on the basis of the comparison; a memory unit designed to store the association made by the association unit; and a dataset generating unit designed to modify the respectively associated second diagnostic dataset (201, 202) on the basis of the sum total of all the first diagnostic datasets (181, 182) associated with the second diagnostic dataset (201, 202), in order to generate at least one third diagnostic dataset (241, 242), wherein the third diagnostic dataset (241, 242) contains a respective set of third diagnostic data and at least one third diagnostic result associated with the set of third diagnostic data; and to store the third diagnostic dataset (241, 242) in a third database; a diagnostic unit designed to facilitate the search for faults on the technical object on the basis of at least one third diagnostic dataset (241, 242). at least one diagnostic tester and at least one diagnosis server, wherein the diagnostic tester has at least one object communication apparatus, which is designed to receive first diagnostic data from at least one object control unit of the technical object, and at least one transmission unit, which is designed to transmit the first diagnostic data to the diagnosis server; wherein the diagnostic tester and/or the diagnosis server are designed to use the first diagnostic data to form at least one set of first diagnostic data that comprises at least some of the first diagnostic data and to associate at least one first diagnostic result with the set of first diagnostic data, a first database designed to store first diagnostic datasets (181, 182) created in the course of successive diagnoses, wherein each of the first diagnostic datasets (181, 182) comprises a respective set of first diagnostic data and the at least one first diagnostic result associated with the set of first diagnostic data, a second database designed to store predefined second diagnostic datasets (201, 202), wherein each of the second diagnostic datasets (201, 202) comprises a respective set of second diagnostic data and a second diagnostic result associated with the set of second diagnostic data, characterized in that the workshop diagnostic system further comprises an evaluation system, having an association unit designed to compare the diagnostic data and/or the diagnostic result of a respective one of the first diagnostic datasets (181, 182) with the diagnostic data and/or the diagnostic result of the predefined second diagnostic datasets (201, 202), and to associate with the respective first diagnostic dataset (181, 182) one of the predefined second diagnostic datasets (201, 202) that has the greatest similarity to the respective first diagnostic dataset (181, 182) on the basis of the comparison; a memory unit designed to store the association made by the association unit; and a dataset generating unit designed to modify the respectively associated second diagnostic dataset (201, 202) on the basis of the sum total of all the first diagnostic datasets (181, 182) associated with the second diagnostic dataset (201, 202), in order to generate at least one third diagnostic dataset (241, 242), wherein the third diagnostic dataset (241, 242) contains a respective set of third diagnostic data and at least one third diagnostic result associated with the set of third diagnostic data; and to store the third diagnostic dataset (241, 242) in a third database; a diagnostic unit designed to facilitate the search for faults on the technical object on the basis of at least one third diagnostic dataset (241, 242).
