2007 525i Code said p0344, I deleted now says p0341 deleted and now says p0340, seem all related to intake cam sensor, but strange the codes changed. Anyways, I know it's on the drivers side of the head and I swear I replaced it last year, could it be related to the vanos solenoids? Had those replaced too with bosche. Last night it lost power and wouldn't run with a crap barely made it home, but getting the part today and hopefully fixes this.
