P2404 Check Engine Light

same issue!
Having the same damn issue on my C6 Avant. Purge valve replaced and they also did a smoke test and couldn't find anything.
Sounds like replacing the gas cap or charcoal canister won't fix it either according to one member? This is redunkulous!
BTW, is the charcoal canister located under the spare tire well like other Audis? I replaced mine before in my B5 S4 and it was simple.

Do not drive the car if the CEL is blinking.

Hello everyone,
My car is 2006 Audi A6 Base-Line.
About a week ago, I had a check engine light on and went to the Autozone to scan the code.
The error code was P2404.
The funny thing is that it came on for couple days and automatically went off.
And, suddenly, it came on again last night.
It never happend past 5 years of driving this vehicle, but once, only once, I put the gas in the tank while the engine was running. I think this might the problem with the issue.
What is going on with my car?
Does anybody have a similar experience that I am having?
I'm out of warranty so I am scared to death to go to dealer.

I’ve researched this topic for years now, and my take is that the only permanent solution is to replace the ECU. Those that have done anything less have had the 2404 return at some point

FACTS. Mine has been replaced for 2 years now and the dreaded 2404 has not come back. Bite the bullet.
