I have had a problem recently with juddering and slight loss of power when accelerating.
Finally Audi had tracked down a leak on one of the vacuum hoses.

They quoted me £450 for the work and £150 for parts claiming they need to remove the inlet manifold to do the work.

I toldthem no of course, but now I need some help.

Firstly,I need a pointer as to where I can get the hoses cheep, and or better hoses?
Secondly, do I need to remove the inlet manifold to replace these? Is it an easy job?

Audi recommend I replace all my vacuum hoses and I do agree on this one as it's done over 100k.

Thanks in advance for any advice.
