BTW I changed my timing belt today and I forgot one screw somewhere I am sure it is not anything from engine parts. It is Allen 6mm bolt with big washer on it...
here is the picture: http://i11.ebayimg.com/04/i/000/9f/6e/de28_2.JPG
washer: http://www.americanmodeleng.com/site.../washer.01.jpg
Update: that bolt was old bolt form tensioner roller, new one came with the roller and it was installed with the roller.

based on the code is this leak between the LDP and fuel tank?
I have the same issue on my A4 2.8 30v and am going crazy looking for the EVAP diagram to see how this crap works, the flow and also where these damn hoses run and are connected to.
In my case, ( not sure if it happened during this ) I changed my rear o2 sensor a week ago and a day later the CEL came back on. with 17884 evap leak detection pump insufficient vacuum.
I want to know what hose is this LDP vacuuming pressure from?

Also I got the repair manual form my friend and I will try to check all those connections and leaks when I get a chance . Also something here was saying LDP low vacuum so I might check LeakDetectioPump it that LDP stands for

Nah, the whole purpose of evap system is to burn and get rid of fuel vapor created during normal operating process, so that it does not contaminate atmosphere. It will not affect performance of the car as long as you don't have a leak before the purge valve. (aka N80 valve) Also if you had a leak before the N80 valve, you would not get the same trouble code.
I would just check all the vacuum lines and connections first.
