As Gale wisely recommended, put the switch inside a ziplock plastic bag and disassemble with the aid of a small screwdriver. Be careful, there are several small springs. Spray all the contacts with contact cleaner and re-assemble. Before re-installing, spray the electrical connector with the contact cleaner.
This should cure the moving seat syndrome.
Unfortunately no repair was mentioned, only temporary mesures ,I guess so one could drive "safely" to a stealer. I can't set the seat in one position because I am altruistic and I allow other members of the family to drive the car.
There is something in the seat ( a switch or a relay, that makes a clicking sound at the same time as the seat is moving. It is dependent on the shape rather then the weight of the driver's bottom, as it triggers most when our 20 y.old slim 180 lbs uses it on a bumpy road.
Is there a difference in design between 93/940i and 735 ?
Thank you for your suggestion.
It worked (at least for the time being), but it wasn't the memory switch. It was the seat manual adjustment switch. I did not dismantle either of them, but dip them whole in clean alcohol (skin scrub)shook wigorously and let them dry in the sun.
