the exit feature of the seat, wheel, etc. memory for my 98 750il is not functioning. the individual memory buttons function. you must hold the button thill the positions are achieved. Had a modic scan at the dealer when I bought the car - was told by the tech that it was common that year and that replacing the seat switch would supply updated software to enable the feature. I have installed the new switch and there is no change - other than I had to re-establish the seat, memory wheel postions etc. can anyone shed some light on this please. The dealers diagnosis/recomendation appears to have failed. Being a bit on the "portly" side. this feature would be a great improvement
