I don't think there is a download, but the next time I replace these on my wagon I'll do one then.
It is a pretty simple job to do.
1) Remove the intercooler (these instructions are within downloads, ? setting tappets)
2) on the left hand side of the engine as you look from the front into the engine bay you will see the injectors & the metal fuel pipes, and connecting each injector & the number 1 injector back to the fuel system is a rubber braided coated pipe, 4 sections, 3 between each injector, then a longer section from number 1 injector back to the fuel system. Number 4 injector also has a small blanked off cap, on mine a 3 cm section of hose with a screw in the end to seal it.
3) Remove each ection of hose individually, cut a new piece to the right length & replace. The tricky one is the long pipe from Number 1 back to the fuel system, I use a long handled clamp to do this job properly. Don;t forget to replace the very short section on number 4 either.
I've had my wagon 3 years, and have done this job 3 times, so it is quite a normal thing to happen. Do sort it becuase if you leave it it can go down the back of the engine and cause a slipping clutch due to fuel contamination.
