Not sure what the hell the sensor under the hood is though.
the prices at dealer are roughly.. $200 for speed sensor, or $1500 for the "speed sensor" (i assume module) under hood
i dont want to pay bmw a penny.. i tested the speed sensor (as much as i could without any specs to compare..
i compared the "faulty" speed sensor on left side.. to the one that did not come up as faulty on the right... identical specs..
i asked bmw, they said the speed sensor is underneath the hood.. i dont know why they call it a speed sensor, i assume its a module.. they said that is faulty, i dont really want to waste an extra $200 if it isnt the speed sensor ..
scanner popped up Front Left signal plausibilty,
so i compared voltages and resistances from left to right...and its identical
