hello my e46 320d is a EU3 engine and was first registered on 04/09/2003
my question is if i replace the MAF do i have to get it coded or can i just buy the part and fit it?
also is this the same as the MAP sensor.
i want to replace both and was wondering if i can just go to the dealer and simply fit the parts my self and all will be well.
thanks for the help
