Default How bad have I hurt my car/turbo???

I have been chasing some P0172 and P0175 Fuel System Too Rich (Bank 1 &2) and very poor fuel milage. found some bad vacuum lines (fixed) tested MAF by unplugging to see if idle changed (no change). so I used the smoke/pressure tester at work and had a leak below the air box. it looks like the banjo bolt holding the line from the N75 valve has fallen out. I do not know how long it has been gone.
1: how bad have I hurt the car/turbo?
2: Anyone know what size the banjo bolt is so I can fix this?

Thanks
2002 A6 w/auto

ps also found a small leak on the y boot going to the throttle body. easy fix

I did not rember to take pictures of the install. There was alot of cursing some yelling. It was not fun trying to get the bolt installed with the two gaskets. I did have to go the napa to find extra gaskets because they keep falling. But new bolt in and leak checked and no leak. So far.
