    Have you tried tightening them if you have no luck with that it could be copper washers that are the cause can't really see and I have a different lump but don't go nuts with the tightening

    Think i will attempt to tighten them up to see if they budge but it does look like the bolt is worn which isn't the best thing in the world and what about the black cap? i did see it dripping from there too but it might have started from above?

    Just out of curiosity, does it cost much to replace that pipe? and what is it called?

    Just looks like a fuel pipe that someone's tried to botch with a fibre washer. If you've not had the car long, take it back and tell them to fix it, although a new union bolt and washers may do the trick. It's a hollow bolt, so go easy on any tightening.

    Yeah i got it from a garage so hopefully they will sort it for me but it's a good 60 miles away! not sure if the petrol is worth it unless they pay for petrol!, would it be cheaper it give it a shot myself with the bolt etc? or just get my mechanic friend to sort it?

    I had an o ring failure on my fuel pump after a remap recently. Quick fix bit was leaking fuel quite badly.

    I'd get it checked out ASAP, fuel leaking into a hot engine bay could be bad news.

    There might be a problem with damage to the faces on the nut and/or pipe end. If you can see the pipe is OK, then have a good look at the bolt. If in doubt, get a new one. Or order one anyway?

    If it has O rings and they are the reason it leaked in the first place, make sure they come with the bolt. Probably all it needs.

    What is the pipe called just in case i need to order a new one? will it come with bolts if new?, is it an easy fix just a straight replacement?

    Don't think it will come with bolts.
    Can you get at the other end? If it's accessible at both ends, then it's just a straight swap.
    Seeing as petrol squirts out with the ignition on, it's a fuel supply pipe; make sure everything is spotless when you put it back together.
    If you aren't confident about diy, have you got a mechanically-minded friend or a local garage you can trust? It wouldn't cost the earth to get it fitted locally.

    PS, it only needs the smallest of nicks in an O ring for petrol to piss out!!!

    Do you know anywhere i can get the bolts from?, yeah i can see both ends (i think) i have a mechanic friend so i'll just get him to do the work, yes it's definitely the fuel supply pipe i think it's definitely the reason my miles go down really fast because as soon as the ignition turns on it just pisses out haha!, how do you know when to stop tightening so the 0 ring doesn't split? do i need washers too?

    You'll only get them from Audi, I think. I haven't done an Audi but it should be one or the other, not both I think.
    Your mechanic friend will know when enough is enough.

    Thanks, do you know if the pipe next to it is connected to that pipe or are they individual? do you think first i should try replace the bolt and washers if it doesn't work then order a new pipe?

    Looking at the pic, they appear to be separate. You can't do any harm by changing the bolt and washers/rings first. If that doesn't work, you know the pipe's faulty; if you do have to get a new pipe after trying new bolt and rings/washers, make sure to get another set of them.

    The good news is that the garage i bought it from are going to repair it free of charge but the bad news is that i could be without a car for a week or two weeks! :(

    I really appreciate everyone's help!

    Thankyou!
