Was doing my summer tires this weekend and saw this near rear passenger jack point. What is this unhooked hose?

[SteveKen]

EVAP going to the N80 valve situated above the SAI pump.

Were you getting any errors?

[Dmb408]

Yes, I have the P0420 that I am taking it in for this week (but I was fairly certain it's being caused by a leak somewhere in my milltek clamps, near the CAT). But I have somewhat bad idle on start up, when SAI would run, just slight up and down surging. Would this have caused it?!?!

I am hoping the P0420 is not the O2's though...we'll see this week. This is when I wish I had Vag Com and just not a good general code reader.

Do you have coilovers? Isn't this the hard line for DRC?

[Dmb408]

I have DRC (recently recharged and running great, this couldn't be DRC unless DRC has a breather hose) and Hotchkiss sways.

[SteveKen]

The DRC line is the hard one just above that one. I can 100% say that it goes to the N80 valve. I recently replace the tank and all the fuel and EVAP lines on my S6 conversion.

BTW, it is just a push until it snaps/clicks locked type connection. Easy to put together but pretty hard to remove.

If you haven't' done it yet, connect it.

[Dmb408]

I realized that it was that type of connection but it didn't click... (maybe busted...)

Do you have coilovers? Isn't this the hard line for DRC?All DRC hard lines are bolted connections in order to handle the extreme hydraulic pressures. This is an EVAP line.

Sorry a little blurry. There are two large diameter lines and one small one. The large diameter on the inside is the fuel pressure line, the middle small one is the fuel return line. The large line to the outside (looking front to rear next to the center tunnel) is the Evap line (disconnected on yours).

I see it. Thanks.
