Tdi guyz step in . Cold weather

9-12 pending which route I take. should be getting 15-18. yeah somethings up with the truck but I have little time and patience to deal with it now. I could list everything I’ve checked and or replaced but this isn’t the place for such a long list. I honestly just think it’s a tired motor at this point. They did beat the living shit out of it on the one lap a few years back.
