Question
my 330i has recently thrown two codes P171 & P172 they told me it was the
mass air sensor so we ordered a new one (OEM) now that we received it
and installed it in the car it will still not start. My questions is. Is their anything
I half to do before it will start. The car was not starting to begain with. Does
the computer half to be reseat????
Well I think you have jumped into replacing parts before not actually know what was wrong.You may have to reprogram things as I don't know what year your car is.And as for the codes I am not familiar with those numbers as the recent numbers are 4 digit.Was there a "0" in front of the numbers?
