Perhaps not the sort of advice you are looking for, but.....having sized this job up ( think i found a guide on an audi site? All sorts of bent/modified spanners used, and associated contortions!) decided to get it fitted for me.
I had already decided to get the supplier to fit my new Loba HPFP pp, because the terms of Lobas warranty appear to give them wriggle room if not fitted by an auto mech.
Although a well qualified engineer, i have learnt over many years that some jobs are best passed to a specialist! NOT worth the aggro for an old fella like me!
So last thurs had an RS4 vv fited to my Ed30 at TSR at the same time as my new Loba (great deal).
The mech (smallish young fella, well equipped) doing the job took just under 2 hours to fit both, and i watched him do most of the vv job. Looks and absolute b@st@rd job?
Money well spent in my book - probably < £45?
Looking forward to my APR 2+ next month!
