My X5 will run ok for a few miles then these code's will show up on my scan tool. I found the Y-Duct that is part of the air intake hose's had large cracks in between the rib's (small ribed section of the y-duct). I tryed to seal them with a silicon that I had used when I installed a [COLOR=blue !important][COLOR=blue !important]pellet [COLOR=blue !important]stove[/COLOR][/COLOR][/COLOR]. It does not slump & dry's flexible. I ran the car a little further this time before the code's came back. I removed the y-duct from the car this time & found 2 more small cracks in between the ribs. I have sealed with the same silicone again, & will let dry overnight.

Does anyone have any other idea's (if anything) that would set these code's. The P0171, & P0174 come up first & then within a few miles the rest of the fault code's show up.
I have ordered the new y-duct.

Thanks you in advance.
Jay
