Looks like I have to replace the 2 metal feed/return pipes running under the drivers side sill.
They run between 2 splitters so as far as I can see replacing them is pretty straightforward.
However, I am a little worried about the possibility of having to bleed the system after as I assume I will have to drain off any diesel left each end when I undo the pipes...
Has anyone had experience with this?
(Oh, and Audi wanted just shy of £200 for a fuel line 'kit' so any pointers in the right direction for lines would be much appreciated!)
