Hello, I have a few questions about a Porsche 911 Carrera 4S where I hope you will help me. The problems are as follows: – Airbag: The airbag lamp has been lit for some time. So far, the old workshop could not find the error. – Seat: The electric seat adjustment of the rear seat back does not work anymore. Via the button on the seat, this can no longer be adjusted in the inclination. Also the pre-programmed seat adjustment which via the e Buttons on the door or with the key should work, only goes in the sitting position forward or back. Nothing happens here in the inclination either. – Reading the ECU: After reading the ECU out today, I find the following error codes, which after research in the net do not really tell me anything. Maybe you have more experience here: Car Scanner ELM OBD2 DTC report =================1======================= 1281 Raw code: 000501 ECU: 15.
