Hello everybody, my 93er T5 has a problem with the seat adjustment. The driver’s seat only drives jerkwise, millimeters by millimeter. It doesn’t do that for all engines and not in every direction. In fact, back and back always goes, back and seat down as well. Seat up and back forward only jerkwise, the memory function doesn’t work anymore. With the passenger’s seat everything is OK, control units have already changed (driver side – passenger side) oh e Effect. What can that be? Greetings from Switzerland, Roland
