My friend Chris' '90 GT has the codes 383 and 387 for sport seats, but has comfort seats and seat memory on the driver's side. The memory works, but the door panel may not be the original as it has a leather wrapped handle and the passenger side doesn't.
Most likely the sport seats were swapped out for comfort seats?? Along with the door panel containing the memory buttons??
Are build stickers always correct??
He would have loved to get sport seats...
I think I understand your question, but not certain. If the build sticker shows sport seats, why is there a memory control wiring on the drivers door panel, and why does it all work?
If that's a summary of the question, there are two possible answers. first, that the door panel, seat memory control, and the seats were swapped from another car, and the wiring was already there, just not connected to the seat control module. Second, that the car left the factory with memory seats, but the build sheet is wrong.
you have some evidence that the door panel was swapped, and that would be my best guess. The option codes should represent the car exactly, and the Germans are pretty fanatical about details like this. I would guess that there is significant wiring that exists in each car harness that isn't used on each car. The seat memory would be one of the circuits that would be present on every wire harness, but only connected on cars with that option. The controller, panel, switches, and seat are easily available, and the stubs of the connectors would be at the door, and under each seat. It's possible that the pass side memory seat is not on the standard wiring harness, and thus not present on the car. It could be added by finding the wire bundle for the pass side, but that's a bunch of work.
As you mentioned, someone would love to have sport vs memory(comfort) seats, and at some time in the past, it was swapped on that car, and hooked up with the controller.
There are many cars which do not have all options listed but AFAIK mistakes on codes is rare. Meaning if sticker says you should have sport seats comforts are most likely later change.
My '91 has the memory harness on both sides but memory panel on only the driver's side. I thought that all 928s had the harness on both sides regardless of whether the option was ordered and the button panel installed? I remember, long ago, lots of folks adding memory easily to their seats?
