Some BMW's you have to leave with just the ignition on for 25 sec's after changing rake sensors (it resets the fault memories) but I think your car is to early The sensors are easy to test just bridge them and watch the light. If this fail they are feed from the instrument cluster it's a single that loops through both sensors and goes to earth so if you put a volt meter anywhere on this circuit between the wirer and earth you should see 7volts (I think but it's less than 12v)
