Hi Everyone,

I went to fill up my car at a Mobil station. Filled it up, went to start it, and the idle was horrible. Tryed to restart the car a few times and eventually it ran like normal again. The next day a CEL came up.

It read P0441 (16825). Retightened the gas cap, cleared the code with an OBDII scanner, drove it a day and the CEL came back.

Anyone have this come up before? Doing a search, only a few posts came up. Some mentioned a N80 valve or charcoal canister..has anyone changed either of these on their TT??

Thanks,

Some cars do this when you try to stuff all the gas you can in there. It wlll probably clear itself...

My daughters Mazda used t do this until she stopped filling at the click..

Another poster who just sold a car had his buyer do this on the way home..Unfortunately in that case the dealer fleeced him for $1K in work.

I was thinking it was bad gas or something, since the car ran really odd when I started it to leave the gas station..

but after that initial weird start up, the car started up/ran fine, but the next day that code came up...

Looking at the golf/jetta forums, a few guys got the same code and people suggested it being a bad n80 valve.

I just don't know where this valve is located.


Thanks for your quick reply

In the spare tire hump, accessed from below.

For now I'd clear the code and see if it returns..

remove the muffler/heatshield to access that EVAP spare tire hump area?

Is that where the n80 valve is located at?..

thanks again.

..now i just gotta find the part number for it..

vortex 1.8t forum lists the part# to be 0 280 142 354, but it doesn't come up on any of the VW/Audi parts sites..

..actually..there's probably a chance the part# is on the part itself..i'll have to check that out..

thanks,
