I just spent way too much time reading through these 8 pages of NONSENSE by the OP.
I'm happy to see the E90 community come out and try to help each other out! But you are WASTING your time with this valentine guy, he's so dense, you give him good advice and then he responds with two word answers. Its hard to help someone that wont help themselves, and this guy is not doing himself any favors. This guy is not very smart, plain and simple and you guys are wasting your time. I feel, like many of you, that he is leaving out other details to this situation.
That being said, I'm happy i have a CPO warranty for 14 more months! Only issue i've had with my N54 is 3 injectors malfunctioning. Also, my evaporator went out.
