Tach municipality, battery exchange made at Porsche. After the vehicle, looked into the on-board folder, vehicle ticket not in. I delivered the because this car was for the first time with Porsche and was installed. Directly went in again, reported -> Schein missing. Employees with the vehicle, checked at the usual places -> Conclusion Schein not there. Friday 2 pm. Statement staff – check again at home – we check again here. Call 3 pm PZ, communicated exam to home closed – nothing found, please search in the PZ so I can still pick up the ticket today. No feedback. Saturday again called, statement we look and report. I asked for when then? I need this when I am stopped. We’ll get in touch at some point next week, emphasis on “someone” – absout groundless naughtiness. So far no feedback. What to do? 🙁
