Hi all,having a couple of teething probs with my zed-the emmisions light came on just before new year-took it to dealer(non bmw),who said it looks like a sensor trip due to the cold :? -they took light off and it has stayed off but does anyone know if the zeds are like the e46's which re calibrate over 100 miles and then come back on?-ive got a years warranty with it but just curious-thanks.
