Seat memory: wrong length adjustment

Dear Phaetonauten From one day to the other, the seating positions (longitudinal adjustment) of all three positions in my 18-way driver’s seat changed. I opened the driver’s door via Keyless, whereby I (as usual because I had previously driven) fixed no change in the seating position. Since my wife provided herself as a chauffeur, I called her sitting position via the corresponding memory button. I was surprised that the seat went very far forward. ng I got with my wife’s comment after boarding: I’m not that small again! Pressing the memory button again didn’t work, so she drove back the seat “manual-electrically”. I wanted to drive the Phaeton into the garage at home. My wife gets out, I call my seat position via the memory button, seat drives back, I get in – and also feel trapped! Long speech short sense: The length adjustment is in all three storage places The other parameters (seat height, backrest, headrest, straps, steering wheel, mirror) have not been changed. After the correct position has been stored again, it seems to work again. Nevertheless, the question: Who has experienced something similar and can tell me what it is about? Thank you very much and Gruss CH_V8
