Since I purchased my '98 355 Spyder earlier this year, I've noticed that the drivers seat does not move forward very much during top cycling. It's really not enough to prevent interference with the seat. So, this weekend I ran both seats back to the rear stop and then cycled the top while recording the temporary forward positions of the seats. The passenger seat moves forward a bit over 3", then returns to the rear stop. The drivers seat moves (a whopping) 1", then returns to the rear. I've heard of the position sensors flying south and not coming back, but this seems more like a calibration problem. Has anyone had this happen to them? Does anyone know if you can do anything to allow the sensor to "re-learn" where it should be? Thanks!
