Carbon canister - correct part?

[Dr Mike Oxgreen]

I asked this question on a Škoda forum but I’m not getting any replies, so I’ll try here!

It’s probably a common part on multiple VAG engines…

I’m replacing the N80 valve and carbon canister on my 2012 (pre-facelift) 3.6 VR6 Superb, in the hope of curing an occasional P0441 Incorrect Purge Flow fault code. Swapping the filler cap hasn’t worked.

The carbon canister I’ve just received (link below) has an extra downward-pointing vent pipe about an inch or so long in one corner, which is not present on the one currently fitted. Is this simply a modification introduced on newer revisions of the part, or have I got the wrong thing? Does anything attach to it, or does it just remain open?

The way to properly find out would be to look at a parts diagram and look at the notes accompanying the superseded part listing. At a guess, it probably says to blank off the extra fitting.

I should have clarified - the extra plastic tube doesn’t look like a fitting that’s designed to have a hose attached to it. It doesn’t have a barbed shape (unlike the inlet fitting on the top, which is barbed). The tube is completely smooth and straight-sided, so even with a hose clamp I struggle to imagine a hose fitting onto it securely.

Has anyone fitted a carbon canister to a VR6, or own a VAG car whose carbon canister has this tube? Can you confirm my strong suspicion that nothing is meant to be fitted to it?
