P0171&P0174 codes pop up. anyone have a clue??
so im going to need an inspection in january and my car still has these two codes that pop up:
P0171-BANK 1 SYSTEM TOO LEAN (it could be bank 2)
P0174-BANK 2 SYSTEM TOO LEAN (it could be bank 1)
i cant remember too well which was bank 1 or 2. now, when i initially found these codes, it was before we replaced the crank case ventilation valve. im curious if those codes had to do anything with the ccv. we replaced the ccv ourselves because BMW was going to charge me $880 and when they gave me the order form that they were going to use to order the parts (saying it was the ccv), it didnt even include a ccv. it included a "pressure regulator" and some tubes and hoses.
OKAY, sorry.. now my QUESTION is: is there a way i can clear those codes? or would i really need a new pressure regulator according to those codes..?
ive googled as much info as i could on those two codes and i see millions of different things on fuel injectors and so on and so forth. it never says "this is what is wrong with your car" and unfortunately, i dont trust bmw enough to leave my car in their hands again.
