CEL and codes I pulled
Ok lets just get right to it..
VAG-COM Version: Release 311.2-N
Ledford
Control Module Part Number: 3B0 907 551 BH
Component and/or Version: 2.8L V6/5V G 0002
Software Coding: 07252
Work Shop Code: WSC 02325
Additional Info: WAUEH64B91N030550 AUZ7Z0Y1506556
2 Faults Found:
16825 - EVAP Emission Control Sys: Incorrect Flow
P0441 - 35-10 - - - Intermittent
17585 - Bank2: O2S (Lambda) Correction Behind Catalyst: Control Limit Reached
P1177 - 35-00 - -
I am guessing the second one is rhe rear O2 sensor... (bank 2 and all) but what do I need to look for for the first one.. I alreadt cleared these once and they ar both back.. Probably related...

RE: CEL and codes I pulled
I got the same thing out of my B6 A4. "EVAP Emission control..." Last week my front passenger tire blew out and it cut a small black tube that runs just behind the wheel. I removed the damaged part and patched it with a new piece and the engine light came back on. Do you guys have any idea what may be wrong with the car?
Thanks
Thanks

The evap incorrect purge flow will most likly be caused by a vacuum leak somewhere between the fuel tank and the point where the evap purge valve dumps its vacuum into the engine. In many cases the evap purge valve sticks causing it to bleed vacuum when its supposed to be closed or not allow vacuum to flow when voltage is applyed to the valve. You can check that with a vacuum pump and a scan tool to activate the valve.
Another possiblitly is a saturated charcoal canister. This usually happens when a fuel tank is topped off to far. If this is the case you most likly will have fuel in the line at the evap purge valve. Or at least some wet fuel residue on the line.

Sorry, I just did a search about the code I got and this seemed to be the most relevant one that I found so I posted here.
Thanks for the diagrams Dave, my car has the 1.8T engine but I assume the valve location is the same.

Dave, based on the problem i had with my tire blowing out and taking out that line what else do you think I should try if the EVAP purge valve tests fine? I'm used to working on old american musle cars with more simple engine bays so any help would be appreciated.
