My 04 325ci has been throwing these codes with the ses light. Got my code ran at AutoZone but all they said was i needed a new maf, which i dont. Went to a bmw tech and my boots are good and ive met up with another tech luckily who showed my my problem on the spot, it is a vacuum leak and the part thats messed up is the size of a pen cap about 1/4 inch diameter, but i can't find the part myself and even after he showed it to me i cant recall where it was exactly, i was wondering if anyone else has had this same problem and could help out anyway. ive been trying to find it on realoemparts but cant seem to grasp it on this diagram: http://www.realoem.com/bmw/partgrp.d...10&hg=11&fg=45 it looks like part #9 or in: http://www.realoem.com/bmw/partgrp.d...10&hg=11&fg=40 part #17. any help or any tips, ideas would be awesome
Thanks
