Well it looks like the old vacuum leak/o2 sensor gremlin the PO mentioned has returned.

P0174 arrived tonight along with 10% fuel trims.

I've got an OEM MAF I'm gonna swap in since it's got a duralast whatever right now. There doesn't seem to be a vacuum leak but CCV definitely needs replacing either way due to build up inside of it.

I wouldn't think there's a vacuum leak since it's only throwing the bank 2 code and not both. If MAF doesn't solve the FT's I'm going to try swapping the o2 sensors to see if the code follows the potentially bad sensor, replace that sensor if bad.

Also need to take care of the coolant situation since I blew an upper radiator hose and had to fill it with water to limp home, temps pegged at 215 F even after bleeding it the best I could on the side of the road. Need to flush/fill and properly bleed before driving again.

This months BMW bill is gonna be bigger than I'd hoped.
