So, this morning two packages appeared on the door step, one being the Foxwell for the Cayenne (needed to reset the oil service message!) Second was the CCV hose from Tune-my-euro. Nice item, was only 5 minutes to click the original clamps back on and re-assemble the whole lower intake duct. Et voila! No more CEL. (The little triangle warning is for service requirements.)

I suspect this item had been cracked/broken since a while, as last fall I was having some mysterious messages about DEF efficiency. I guess with the CCV breathing in air after the MAF sensor the whole fuel system is running out of kilter. So now I can get back to regular maintenance and replacing the vac lines and do oil changes.

BTW, does anyone here know how I get to the right procedure in ISTA for brake bleeding while activating ABS?


EDIT: Found this on e90 post, going to take a look if this exists in E70.
"....vehicle management / service function / chassis and suspension / traction control / brake bleeding for special cases) however you can only select the option if you let ISTA/D perform a vehicle test first, otherwise the "display" button is grayed out. Previously, once I entered ISTA/D, I had selected the option to identify the vehicle without conducting a vehicle test. Apparently if you don't let it do the vehicle test and identify the various control units you won't have access to the various control unit procedures."
