05 A6 3.2 engine shuts off randomly
 

It shuts off when sometimes when i start it up and sometimes when im driving.
I've pulled codes out it has one called p2404.
I dont have a vag tool should be here in a couple weeks from total car diagnostics.

Things I've checked were the power to the leak detect pump and power from and going to pcm was good.
Replaced the purge valve I think its called and still didn't fix the issue.
The gas cap was good was checked it was good.

I also herd that code doesn't affect engine shut off?


I looked at tons of forums but none of them really helped.


can anybody help me out with this Id appreciate the help thanks!
