Kilometer manipulated – injection pump to die

Hello Saab friends, I have information that the salesman of my used Saab has given me a ****… Last week I was in the workshop again, this time because the engine control light was on the light. The reading of the error showed that the injection pump reported an error. However, the car worked as always and after the deletion of the error it did not show up again (but did not drive many km afterwards). The interesting thing is that the workshop spec i has found that the amaturating board has very typical scratches that point to disassembling the instrument panel for mileage manipulation. If I still break the injection pump at 118,000 after the turbo can make you suspicious, can I? How can I prove manipulated km? Does anyone have any experience? KM manipulation is apparently on the order of the day after talking to the speci and honest km rather the exception…. Greetings from the S üden, the one with the olive oil in the tank
