    I've started to leak def from fil fill cap on the def tank. Is there some sort of check valve in the system that will not allow the tank to pressurize or is there any other fix for losing def from the cap?

    15 VNL 670 with a D13 btw

    Have not experienced that leak yet. Have had DEF pissing out line at exhaust, puking 25 litres every 700 kms

    I spoke to a dealer shortly after this post. The parts guy had no idea either and said to try swapping caps first. So that's the current plan.
