Took off the engine covers to get to the vac lines and the IM. Was poking around to see if the EGR cooler spring was functional when I came across this little beauty.....

So, this piece of flex pipe comes with a sensor attached, not yet sure which sensor that is but the price for the piece with the electrical items is $179.99. Lovely....

While searching for the part number (haven't found the correct item on realoem yet) I came across an item on Facebook that is just the flex pipe for $18 from an outfit in Dallas, GA. It is on this website: <https://www.tunemyeuro.com/ccv-hose-for-bmw-diesel-3-0l-engine-m57-x5-35d-535d-and-335d-aar2238/> It is labeled "CCV hose".

Ordered it and while waiting for its arrival I will dig around in the vac lines. They look pretty sorry but can't find any obvious leak yet.
