bmw cold start issues/stalling/crank no start/ck engine
I have a 2003 bmw 325i in my shop with check engine codes p1632 throttle valve adaptions not met-p1634 throttle value test failed-p16a0 manufacture code-the car came in running good sat over night started next morning and these codes came on. we cleared all codes and did a throttle relearn and drive cycled all monitors turned over except evap. we let sit overnight to recheck in am and same issues started up then stalled out then wouldn't turn back over hooked scanner up and pulled same codes-found tsb from bmw to replace the throttle body and engine harness and also other people on forum had said. so we tried that with the dealer harness and a junk yard throttle body and drive cycled and let sit over night again. the next morning same issue but only codes p1634-and p16a0 came back. could someone please lead me in the right direction here im totally lost someone telling me possible the ecm?
