Hi all- I've been chasing down electrical gremlins in my new-to-me 2006 GTI and thought I would share the simple solution to my P2401 code:
Check that there is a 10A fuse in the SB10 fuse location in the engine bay.
Since I don't have the original manual for the car, I have been using the attached fuse diagram to troubleshoot. It lists SB10 as "not used," however, digging through other forum posts, I found this thread on Vortex where they mention that SB10 requires a 10A fuse. I popped one in, and voila, no more P2401 code!
I don't know how widespread this diagram issue is- my local shop also didn't know that SB10 required a fuse, and quoted me hundreds just to track down the issue.
If this doesn't fix your problem, you might be stuck having to check the other common culprits (gas cap, N80 valve, etc), but if you're like me and you're using a bad fuse diagram, you're in for a rough time troubleshooting! So far, I've been incredibly lucky and have resolved three evap codes by just by checking and replacing fuses (both O2 sensors and the evap pump).
Hopefully this helps someone out there with similar problems to me!
